example 1

[0079] A 75-year-old female patient was diagnosed with aortic dissection (Stanford type A) according to the examination results of other hospitals after arriving in the emergency department of our hospital. The patient's basic information, preoperative laboratory examination, and imaging examination results were collected. The patient complained of sudden severe chest pain for 2 days, accompanied by coma. Laboratory examination found that the patient's D-dimer was >12000ng / ml; combined with the patient's CT imaging report, cardiac color Doppler ultrasound, and electrocardiogram report, it was found that the patient had an average ascending aortic diameter ≥ 55mm measured by TTE, and a large amount of pericardial effusion , CTA dissection involving the right common carotid artery, celiac trunk and other important branches, dissection false lumen without thrombus, thoracic aorta false lumen ratio ≥ 0.75, electrocardiogram myocardial ischemia. Bringing the patient data into the m...

[0081] A 58-year-old female patient was diagnosed with aortic dissection (Stanford type A) according to the examination results of other hospitals after arriving in the emergency department of our hospital. The patient's basic information, preoperative laboratory examination, and imaging examination results were collected. The patient complained of sudden severe chest pain for 1 day, accompanied by numbness of the right lower extremity. Laboratory examination found that the patient's D-dimer was >12000 ng / ml; combined with the patient's CT imaging report, cardiac color Doppler ultrasound, and electrocardiogram report in our hospital, it was found that the patient had an average ascending aortic diameter ≥ 55 mm measured by TTE, and CTA dissection involving the right Common carotid artery, bilateral iliac artery and other important branches, dissection false lumen without thrombus, thoracic aorta false lumen ratio ≥ 0.75, electrocardiogram myocardial ischemia. Bringing the pati...

Abstract

The invention discloses a method and a device for establishing an acute Stanford A-type aortic dissection preoperative risk assessment model. The method comprises the following steps: screening acquired patient data to obtain patient data meeting a preset grouping condition; performing single-factor analysis on the patient data to obtain a first variable belonging to a preset threshold range; obtaining a second variable belonging to the preset threshold range in multi-factor analysis based on stepwise logistic regression multivariable analysis of the first variable; and forcibly bringing the second variable, a preset age variable and a preset gender variable into a regression equation, and establishing a preoperative risk assessment model. According to the method, the preoperative risk isevaluated through the established preoperative risk evaluation model, and the preoperative early death risk of an ADA patient can be predicted for emergency rooms of various institutions, so that a timely, effective and reasonable diagnosis and treatment scheme can be made according to a risk prediction result, the time for waiting for an operation by a high-risk patient is shortened, and the prognosis of the patient is improved.

Description

technical field [0001] The present invention relates to the technical field of medical software, in particular to a method, device, terminal equipment and storage medium for establishing an acute Stanford type A aortic dissection preoperative risk assessment model. Background technique [0002] Acute aortic dissection (AAD) is a rare, life-threatening condition whose diagnosis and treatment remain a challenge. According to the Stanford classification, AAD patients involving the ascending aorta are classified as type A, and acute aortic dissection type A (AADA) usually requires urgent surgical treatment in the acute phase; without surgical treatment, 50% of patients in the Death within 24 hours of onset, the mortality rate is about 1%-2% per hour. Despite advances in surgical treatment in recent years, the surgical mortality rate is still as high as 25%. The absence of death risk assessment will affect medical decision-making and resource allocation for high-risk patients, ...
