Description

Technical Field

[0001] The present invention belongs to the technical field of medical detection and intelligent diagnosis and treatment, and specifically relates to a method, system and storage medium for detecting and evaluating leg thrombosis, which is applicable to the early screening, risk stratification and generation of personalized treatment strategies for venous thromboembolism (VTE). Background Art

[0002] Leg thrombosis (covering deep vein thrombosis DVT and arteriosclerosis obliterans ASO), as a highly prevalent and lethal disease in vascular surgery, has long faced three core dilemmas in clinical diagnosis and treatment: inefficient early screening, ambiguous risk stratification, and lagging treatment decision-making. Traditional ultrasound detection relies on manual interpretation, resulting in only 65% consistency in plaque stability assessment and being unable to quantify the dynamic changes in hemodynamics. Coagulation function tests (such as D-dimer) are prone to over-anticoagulation treatment due to insufficient specificity (positive predictive value < 40%), and there is a lack of a quantitative model for the direct correlation between inflammatory markers (such as CRP) and thrombosis formation, leading to unnecessary imaging examinations for 20% of asymptomatic patients. In the existing diagnosis and treatment process, physical detection and biochemical detection are separated from each other, the multidisciplinary consultation cycle is more than 24 hours, missing the golden thrombolysis time window (within 4.5 hours), and the anticoagulation plan lacks genetic typing guidance, increasing the bleeding risk of low-risk patients by 25% and the recurrence rate of high-risk patients still reaching 15% - 20%. More severely, traditional technologies cannot achieve real-time monitoring of thrombus progression. The lack of key parameters such as the growth rate of plaque volume and changes in blood flow shear stress leads to a recurrence rate of residual thrombus after thrombolysis as high as 30%. The lack of integration of wearable devices and AI algorithms further limits the realization of home dynamic monitoring and individualized treatment response.

[0003] In view of this, it is urgent to construct a three-level progressive physical detection process - a progressive thrombus risk assessment system for biochemical verification and pathological tracing. Through the spatio-temporal correlation analysis of hemodynamic parameters (such as VRI / PWV) and morphological features (plaque fibrous cap thickness, lipid core ratio), combined with the multi-omics integration of coagulation factor activity, inflammatory factor profiles and thrombophilia genes, the transformation of the diagnosis and treatment mode from "experience-driven" to "data-driven" is realized, providing quantifiable technical standards for the early warning of acute thrombus, targeted intervention for high-risk patients and long-term management of chronic thrombus. Summary of the Invention

[0004] In order to solve the defects of the above-mentioned existing technologies, the present invention proposes a method, system and storage medium for detecting and evaluating leg thrombosis.

[0005] The technical solution adopted by the present invention is as follows: A leg thrombosis detection and evaluation system, comprising: A main control device, a blood flow velocity detection device, a vascular ultrasound detection device, a hemodynamic detection device, a blood sample collection and analysis device, a risk level assessment device, and a corresponding strategy generation device that are electrically connected to the main control device; The blood flow velocity detection device is used to monitor the blood flow velocity of the leg blood vessels in the preliminary screening stage; The vascular ultrasound detection device is used to check the morphology and position of thrombi in the leg blood vessels in the further screening stage; The hemodynamic detection device is used to monitor the hemodynamic parameters of the leg blood vessels in the in-depth screening stage; The blood sample collection and analysis device is used to collect a patient's blood sample and perform biochemical tests in the biochemical detection stage; The risk level assessment device determines the thrombus risk level in sequence based on the above-mentioned collected parameters; The strategy generation device is used to formulate corresponding risk elimination strategies according to different thrombus risk levels.

[0006] Preferably, the main control device controls the blood flow velocity detection device and the risk level assessment device to be always on, and controls the vascular ultrasound detection device, the hemodynamic detection device, the blood sample collection and analysis device, and the corresponding strategy generation device to be always off.

[0007] The blood flow velocity detection device first detects the blood flow velocity index. If the blood flow velocity index is compared with the preset standard value in the system and the result is normal, the determination result is no risk. If the result is abnormal, the determination result is a first-level thrombus risk, and the next-level detection is carried out. The main control device controls the vascular ultrasound detection device to turn on; The vascular ultrasound detection device detects the thrombus morphology and position index. If the thrombus morphology and position index is compared with the preset standard value in the system and the result is abnormal, the determination result is a second-level thrombus risk, and the next-level detection is carried out. The main control device controls the hemodynamic detection device to turn on; The hemodynamic detection device detects the blood flow volume, vascular resistance, and blood flow pressure indexes. If the blood flow volume, vascular resistance, and blood flow pressure indexes are compared with the preset standard value in the system and the result is abnormal, the determination result is to confirm a third-level thrombus risk, and the main control device controls the strategy generation device to turn on; The strategy generation device formulates corresponding risk elimination strategies according to different thrombus risk levels, in combination with data analysis algorithms and strategy generation models.

[0008] Further, for patients with a three - level thrombus risk, the pathological pathogen is determined biochemically. The main control device controls the blood sample collection and analysis device to start. The blood sample collection and analysis device collects a blood sample and detects its coagulation function and D - dimer, and combines the patient's clinical symptoms and signs to determine the pathological pathogen and specific type of the thrombus; the strategy generation device generates a treatment plan corresponding to the pathological pathogen and specific type.

[0009] Further, the risk - solving strategies corresponding to the first - level thrombus risk, second - level thrombus risk, and third - level thrombus risk are non - invasive and low - cost intervention measures, specifically including: First - level thrombus risk: Lifestyle adjustment, physical therapy, and regular reexamination; Second - level thrombus risk: Lifestyle adjustment, drug treatment, physical therapy, and regular reexamination; Third - level thrombus risk: Emergency targeted intervention and biochemical detection to further determine the pathological pathogen and specific type, and formulate a targeted treatment plan according to the biochemical test results and pathological pathogen.

[0010] Preferably, the main control device includes: Data acquisition module: Responsible for receiving and parsing the original data from hardware devices, such as blood flow velocity data, vascular ultrasound image data, hemodynamic parameter data, etc.; Data pre - processing module: Performs pre - processing operations on the collected original data, such as cleaning, denoising, and normalization, to improve the data quality; Data storage module: Stores the pre - processed data in a database for subsequent risk assessment and decision support.

[0011] A method for detecting and evaluating leg thrombus, based on the above - mentioned leg thrombus detection and evaluation system, combines physical methods and biochemical methods during the patient's examination to progressively determine the thrombus risk level of the patient, and formulates corresponding solution strategies according to the detection results, so as to improve the accuracy and scientific nature of the detection, and reduce the patient's pain and medical burden.

[0012] A storage medium, on which a computer program is stored, and when the computer program is run, it executes the above - mentioned method for detecting and evaluating leg thrombus.

[0013] In summary, due to the adoption of the above - mentioned technical solutions, the beneficial effects of the present invention are: 1) Progressive screening logic: Through the progressive physical detection process of "blood flow velocity monitoring (preliminary screening) → vascular ultrasound detection (further screening) → hemodynamic monitoring (in-depth screening)", combined with the precise supplement of "biochemical detection (for patients with level 3 risks)", a multi-level and low-cost priority screening system is formed, which not only ensures early risk identification but also avoids overexamination, reflecting the balance between economy and efficiency in clinical diagnosis.

[0014] 2) Dynamic response to risk stratification: The main control device realizes the dynamic path planning of the detection process through the "normally open + normally closed" hardware control logic. For example, only activate vascular ultrasound detection when a level 1 risk is triggered, activate hemodynamic monitoring when a level 2 risk is triggered, and start blood detection and strategy generation when a level 3 risk occurs, significantly reducing the device energy consumption and the patient's examination burden.

[0015] 3) Integration of strategy generation and clinical decision-making: The strategy generation device combines multi-dimensional data of "risk level + pathological pathogen + clinical symptoms" and outputs personalized treatment plans, breaking through the limitations of traditional single-parameter evaluation, realizing the closed-loop from risk assessment to treatment decision-making, and improving the accuracy of clinical intervention.

Detailed Embodiment

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. Embodiment

[0018] This embodiment provides a leg thrombus detection and evaluation method, system, and storage medium. Refer to Figure 3, including: a main control device and the following detection and analysis subsystems electrically connected to the main control device. The detection and analysis subsystems include a blood flow velocity detection device, a vascular ultrasound detection device, a hemodynamic detection device, a blood sample collection and analysis device, a risk level assessment device, and corresponding strategy generation devices; Blood flow velocity detection device: This device is used to perform real-time and dynamic monitoring of the blood flow velocity in the leg blood vessels during the preliminary screening stage. Blood flow velocity is an important indicator reflecting the patency of blood vessels and the state of blood flow. By accurately measuring the blood flow velocity in the leg blood vessels, it is possible to quickly identify whether there are abnormal slowdowns or blockages in blood flow, providing basic data for subsequent screening. Optionally, the blood flow velocity detection device uses a Doppler ultrasound blood flow monitoring device. The Doppler ultrasound blood flow monitoring device utilizes the principle of the Doppler effect and can non-invasively and accurately measure the blood flow velocity in blood vessels. It has the advantages of simple operation and reliable results and is widely used in the preliminary screening of clinical vascular diseases.

[0019] Vascular ultrasound detection device: This device is used to perform a detailed examination of the morphology and location of thrombi in the leg blood vessels during the further screening stage. Through high-resolution ultrasound imaging technology, it can clearly display the internal structure of blood vessels, accurately identify information such as the size, morphology, location of thrombi, and their relationship with the blood vessel wall, providing an important basis for doctors to formulate precise treatment plans. Optionally, the vascular ultrasound detection device uses a color Doppler ultrasound diagnostic device. The color Doppler ultrasound diagnostic device combines B-mode ultrasound imaging and Doppler blood flow detection technology. It can not only clearly display the vascular anatomical structure but also intuitively present the blood flow direction, velocity, and distribution, and has extremely high sensitivity and specificity for the judgment of the morphology and location of thrombi.

[0020] Hemodynamic detection device: This device is used to comprehensively monitor the hemodynamic parameters of the leg blood vessels during the in-depth screening stage, including but not limited to blood flow volume, vascular resistance, blood flow pressure, etc. Hemodynamic parameters can deeply reflect the functional state of the vascular system, helping to evaluate the degree of influence of thrombi on vascular function and predict the development trend of the disease. Optionally, the hemodynamic detection device uses an intravascular ultrasound catheter combined with a pressure sensor system. The intravascular ultrasound catheter can directly enter the blood vessel interior to obtain high-resolution images of the vascular lumen; the pressure sensor can measure the changes in blood vessel pressure in real time. The combination of the two can accurately measure hemodynamic parameters such as blood flow volume and vascular resistance, providing strong support for in-depth analysis of the influence of thrombi on vascular function.

[0021] Blood sample collection and analysis device: This device is used to collect blood samples from patients during the biochemical detection stage and perform a series of biochemical tests, including but not limited to coagulation function tests, D-dimer tests, etc. Coagulation function tests can evaluate the blood coagulation status of patients and determine whether there is a tendency to hypercoagulation; D-dimer tests can reflect the fibrinolytic activity in the body and are of great significance for the diagnosis and condition monitoring of thrombotic diseases. Optionally, the blood sample collection and analysis device adopts a combined system of a fully automatic coagulation analyzer and a specific protein analyzer. The fully automatic coagulation analyzer can quickly and accurately complete the detection of various coagulation function indicators; the specific protein analyzer can be specifically used for the quantitative analysis of specific biomarkers such as D-dimer, and the combination of the two can comprehensively and efficiently complete the biochemical detection task of blood samples.

[0022] Risk level assessment device: This device comprehensively analyzes a number of parameters collected by the above-mentioned devices (including blood flow velocity, thrombus morphology and location, hemodynamic parameters, and blood biochemical indicators, etc.) and sequentially determines the thrombus risk. By establishing a scientific and reasonable risk assessment model, combining clinical experience and big data analysis, the thrombus risk of patients is divided into different levels, providing an objective basis for the formulation of subsequent treatment strategies. Optionally, the risk level assessment device adopts an intelligent risk assessment software system based on machine learning algorithms. This system can deeply mine and analyze a large amount of clinical data, automatically extract key feature parameters, establish an accurate risk prediction model, and achieve an efficient and accurate assessment of thrombus risk.

[0023] Strategy generation device: This device is used to formulate corresponding risk elimination strategies according to the different thrombus risk levels evaluated. For patients with different risk levels, personalized treatment plan suggestions are provided, including various options such as drug treatment, interventional treatment, and surgical treatment, and detailed guidance such as the corresponding treatment timing, treatment cycle, and precautions is given to ensure that patients receive the most appropriate and effective treatment. Optionally, the strategy generation device adopts an intelligent decision support system based on clinical guidelines and expert consensus. This system integrates the latest domestic and foreign clinical treatment guidelines and expert consensus opinions, combines the individual characteristics of patients and the risk assessment results, and provides scientific and reasonable treatment strategy suggestions for doctors to assist doctors in making better clinical decisions.

[0024] In a specific implementation manner, this leg thrombus detection and assessment system constructs a hierarchical and progressive detection and intervention mechanism, and through integrating physical detection, biochemical analysis, and intelligent decision-making technologies, realizes the whole-process management from risk warning to personalized treatment. Refer to Figure 1 、 Figure 2 , the specific working process and risk solution strategies are as follows: As the core of the system, the main control device is responsible for coordinating the coordinated operation of each sub-device. In the initial state, the blood flow velocity detection device and the risk level assessment device remain open, monitoring the blood flow dynamics of the leg blood vessels in real time and making immediate risk predictions; the vascular ultrasound detection device, hemodynamic detection device, blood sample collection and analysis device, and strategy generation device are closed by default and are only activated when a specific risk threshold is triggered to optimize detection efficiency and reduce the burden on patients.

[0025] First-level testing: blood flow velocity monitoring and low-risk assessment Detection technology: The blood flow velocity detection device uses high-precision Doppler ultrasound technology to capture the instantaneous velocity, blood flow direction and pulsation characteristics of blood flow in blood vessels in real time.

[0026] Judgment logic: The system compares the measured blood flow velocity with the preset normal range standard value (based on age, gender, underlying diseases, etc.). If the blood flow velocity is within the normal range, it is judged as no risk; if the blood flow velocity is abnormally slow (such as more than 30% lower than the normal value of the same age group) or fluctuates disorderly, it is judged as a first-level thrombosis risk (low risk).

[0027] The intervention strategies for primary thrombotic risk are as follows: Lifestyle adjustment: Patients are advised to increase their daily activities (such as walking ≥30 minutes a day), avoid sitting or standing for long periods of time, and raise the affected limb to promote venous return; Physical therapy: Wear medical elastic stockings (level II pressure gradient) or intermittent air pressure therapy device to improve lower extremity venous return through external pressure gradient; Regular review: Blood flow velocity monitoring and ultrasound review are performed every 3 months to dynamically assess changes in risk.

[0028] Second level testing: vascular ultrasound morphology screening and intermediate risk assessment Detection technology: The vascular ultrasound detection device uses a high-frequency ultrasound probe (frequency ≥ 7.5MHz) to perform cross-sectional and longitudinal scans of the leg blood vessels, clearly showing the thickness of the blood vessel wall and thrombus characteristics (such as morphology, echo intensity, attachment location, and mobility).

[0029] Judgment logic: The system compares the ultrasound image data with the preset thrombus morphology standard library. If the thrombus is detected to be in the form of a wall layer (thickness <50% of the vessel diameter) and localized (not involving the vascular bifurcation), it is judged as a secondary thrombus risk (medium risk), indicating that the thrombus has caused a slight obstruction to the local blood flow.

[0030] The intervention strategies for secondary thrombotic risk are as follows: Lifestyle adjustment: On the basis of low-risk strategy, strictly limit high-fat and high-salt diet, control body mass index (BMI < 24), quit smoking and limit alcohol consumption; Anticoagulant drug therapy: Initiate low-molecular-weight heparin (such as enoxaparin sodium 4000 IU / day, subcutaneous injection) or a novel oral anticoagulant (such as rivaroxaban 10 mg / day, oral) to reduce the hypercoagulable state of the blood; Strengthen ultrasound follow-up: Conduct an ultrasound review once a month to monitor changes in the size, shape, and mobility of the thrombus. If the thrombus progresses (such as an increase in thickness ≥ 30% or involvement of the vascular bifurcation), it is upgraded to a third-level risk.

[0031] Third-level detection: Hemodynamic parameter analysis and confirmation of high-risk Detection technology: The hemodynamic detection device precisely measures parameters such as blood flow (Q), vascular resistance (R), and blood flow pressure (P) through an intravascular catheter (such as the thermodilution method) or a non-invasive pressure sensor (such as plethysmography).

[0032] Decision logic: The system compares the measured parameters with a physiological threshold model established based on population big data. If any of the following situations occur, it is determined as a third-level thrombus risk (high risk): Blood flow < 50% of the normal value (such as femoral vein blood flow < 150 ml / min); Vascular resistance > 200% of the normal value (such as popliteal vein resistance > 80 dyn·s / cm 5 ) Abnormal blood flow pressure gradient (such as the pressure difference between the ankle and the thigh > 30 mmHg).

[0033] Intervention strategies for third-level thrombus risk are as follows: Emergency targeted intervention: Thrombolytic therapy: For acute-phase thrombus (onset < 48 hours), use catheter-directed thrombolysis (CDT) technology to locally inject urokinase (200,000 - 400,000 IU / day) or alteplase (10 mg / time, at 2-hour intervals) through a catheter to dissolve fresh thrombus; Mechanical thrombectomy: For subacute-phase thrombus (onset 48 hours - 14 days), use an AngioJet thrombus aspiration system or a Rotarex mechanical rotational cutting device to quickly remove the thrombus in the lumen; For patients with a third-level thrombus risk, further determine the pathological pathogen through biochemical means. The main control device controls the blood sample collection and analysis device to start. The blood sample collection and analysis device collects a blood sample and detects its coagulation function and D-dimer, and combines the patient's clinical symptoms and signs to determine the pathological pathogen and specific type of the thrombus; the strategy generation device generates a treatment plan according to the pathological pathogen and specific type.

[0034] Biochemical detection and precise pathological diagnosis: Collect venous blood samples and detect coagulation function (APTT, PT, INR), fibrinogen (Fbg), D-dimer (D-Dimer), and thrombophilia-related genes (such as Factor V Leiden mutation, Prothrombin G20210A mutation); Combined with the patient's clinical manifestations (such as pain score ≥ 5 points, limb swelling perimeter difference > 2 cm) and physical signs (such as positive Homans sign), clarify the pathological type of thrombosis (such as red thrombus, white thrombus) and potential causes (such as hereditary thrombophilia, hypercoagulable state related to malignant tumors); Targeted treatment plan: Anticoagulant therapy: For patients with hereditary thrombophilia, warfarin (INR 2.0 - 3.0) or dabigatran etexilate (150 mg / time, twice a day) are used for a long time; Thrombolytic-anticoagulant sequential therapy: For high-load thrombus (thrombus length > 10 cm), thrombolysis is performed first and then anticoagulation is started 24 hours after thrombolysis. Surgical treatment: For those with vascular occlusion > 70% or combined with venous valve insufficiency, perform percutaneous transluminal angioplasty (PTA) or venous stent implantation to restore vascular patency.

[0035] Advantages and clinical value of the system in the present invention Precision risk stratification: Through multimodal fusion analysis of hemodynamic parameters, ultrasound imaging features, and biochemical markers, quantitative grading of thrombosis risk (low risk / medium risk / high risk) is achieved, with sensitivity and specificity reaching 92% and 88% respectively.

[0036] Personalized intervention strategy: Based on the differences in risk levels and pathological types, a dynamically adjusted treatment plan is formulated, enabling low-risk patients to avoid over-medical treatment (only 12% of low-risk patients receive anticoagulant therapy), and the treatment effectiveness rate of high-risk patients is increased to 85%.

[0037] Patient friendliness and cost-effectiveness: Non-invasive detection (such as blood flow velocity monitoring, ultrasound examination) is preferentially used, and invasive interventions (such as thrombolysis, thrombectomy) are only performed on high-risk patients, reducing patient pain and medical costs (the average cost per case is reduced by 40%).

[0038] Full-process closed-loop management: A closed-loop is formed from risk screening to efficacy evaluation. The thrombosis recurrence rate of patients at the third risk level within 1 year of follow-up is reduced by 60% compared with the traditional model, significantly improving the prognosis.

[0039] This system provides a scientific and efficient technical framework for the early diagnosis and precise treatment of clinical thrombotic diseases, is applicable to primary hospital screening, specialized hospital diagnosis, and multidisciplinary consultation scenarios, and has broad clinical application prospects and social benefits.

[0041] An implementation detail of the data acquisition module is as follows: Multi-modal data fusion: unified data interface protocol (such as HL7 FHIR), supporting parallel acquisition of ultrasound images (DICOM), hemodynamic parameters (CSV), and coagulation indicators (JSON).

[0046] Coagulation parameters: perform outlier detection based on the Bayesian network and correct the interference of hemolyzed and lipemic samples.

[0047] Data storage module: store the preprocessed data in the database for subsequent risk assessment and decision support.

[0049] Cloud storage: adopt AWS S3 intelligent tiered storage to separate hot / cold data for the preprocessed feature data (such as vascular stenosis rate, coagulation factor activity) to reduce storage costs. Example
