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 thrombus attribute information obtaining method, device and equipment and a storage medium. The method comprises the steps: constructing an original supportmodel and an original arterial aneurysm model according to a support parameter of a dense net support and a target three-dimensional image; determining a target arterial aneurysm model according to the original support model and the original arterial aneurysm model after the dense net support is placed; performing the computational fluid mechanics simulation based on the target arterial aneurysmmodel according to a preset thrombus forming process, and obtaining a target simulation result; and determining the thrombus attribute information corresponding to the dense net support and the targetthree-dimensional image according to the target simulation result. Through the above technical scheme of the invention, the method achieves the obtaining of the thrombus attribute information after arterial aneurysms of patients are placed on different dense net supports before operation, thereby providing more precise data support for the clinical treatment of the intracranial aneurysm.

Description

technical field [0001] Embodiments of the present invention relate to medical simulation technology, and in particular, to a method, apparatus, 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. [0003] At present, the clinical treatment for intracranial aneurysms is to use interventional methods to place a dense mesh stent (also known as a flow diverter, FD) at the aneurysm to change the hemodynamic state of the aneurysm. , so that thrombus coagulation is formed in the aneurysm cavity, and blood continues to flow into the aneurysm cavity, so as to achieve the therapeutic purpose of preventing the rupture of the aneurysm. [0004] However, under different clinical conditions, placing different brands or types of dense mesh stents may lead to different results. The most...
