Problems solved by technology

[0004] However, under different clinical conditions, the placement of different brands or types of dense mesh stents may lead to different results. The most serious situation is that the dense mesh stents cannot effectively prevent blood from entering the aneurysm cavity, eventually leading to rupture of the aneurysm
That is to say, there is still no clear understanding of whether a thrombus will be formed smoothly and how long it will take to form an effective thrombus after placing a dense mesh stent at the aneurysm, so that it is impossible to formulate a more suitable treatment plan for patients

Abstract

The embodiment of the invention discloses a method, device, equipment and storage medium for acquiring thrombus attribute information. The method includes: constructing an original stent model and an original aneurysm model according to the stent parameters of the dense mesh stent and the target three-dimensional image; according to the original stent model and the original aneurysm model, determining the target after placing the dense mesh stent Aneurysm model; according to the preset thrombus formation equation, based on the target aneurysm model, computational fluid dynamics simulation is performed to obtain the target simulation result; according to the target simulation result, determine the three-dimensional Thrombus attribute information corresponding to the image. Through the above technical solution, it is possible to obtain the thrombus attribute information after different dense mesh stents are placed in the patient's aneurysm before operation, so as to provide more accurate data support for clinical treatment of intracranial aneurysms.

Description

technical field [0001] Embodiments of the present invention relate to medical simulation technology, and in particular to a method, device, device, and storage medium for acquiring thrombus attribute information. Background technique [0002] Intracranial aneurysm refers to a tumor-like protrusion of the arterial wall caused by the localized abnormal expansion of the lumen of the cerebral artery. The incidence rate is increasing year by year, and the mortality rate is high and the prognosis is poor. [0003] At present, the clinical treatment of intracranial aneurysms is to use interventional methods to place dense mesh stents (also known as Flow Diverter, FD) at the aneurysm to change the hemodynamic state at the aneurysm. , so that thrombus coagulates in the aneurysm cavity, preventing blood from continuing to flow into the aneurysm cavity, so as to achieve the therapeutic purpose of preventing aneurysm rupture. [0004] However, under different clinical conditions, the p...
