Problems solved by technology

Virtual minimally invasive endovascular intervention is a method of simulating the implantation of coils / stents in parent arteries through finite element simulation software (such as Abaqus, Ansys, etc.), The means of assessing blood flow changes has the advantages of low risk, can better solve the above-mentioned postoperative complications and can predict the risk of aneurysm embolism prognosis before operation, but this method is based on the finite element method to simulate the spring The implantation of rings / stents has the disadvantage of long simulation calculation time, which is difficult to apply in clinical medicine

Abstract

The invention discloses a method and a device for implanting a virtual stent for an intracranial aneurysm. The method comprises establishing a three-dimensional model of a target parent artery and ananeurysm based on intracranial image data, wherein the three-dimensional model comprises a virtual parent artery of the target parent artery and a virtual aneurysm of the aneurysm; extracting the artery centerline of the virtual parent artery according to the three-dimensional model; scaling the virtual stent based on the artery centerline until the scaled virtual stent meets the preset conditions, implanting the scaled virtual stent into the virtual parent artery and releasing the scaled virtual stent till the maximum displacement increment value is less than the preset displacement incrementvalue. According to the method, the simulation calculation time of the stent simulation implantation can be reduced to assist a doctor to plan a solid stent implantation operation and further improvethe application rate of the solid stent. With the stent simulation implantation as a reference, the solid stent implantation accuracy can be improved to reduce the risk of the solid stent implantation operation and the likelihood of postoperative complications.

Description

technical field [0001] The invention relates to the medical technical field of intracranial aneurysm, in particular to a method and device for implanting a virtual stent for intracranial aneurysm. Background technique [0002] Intracranial aneurysm, also known as cerebral hemangioma, is a tumor-like protrusion on the arterial wall formed by abnormal expansion of the lumen of the intracranial artery. It is a common vascular disease. According to statistics, out of every 100 adults in my country, 7 are carriers of aneurysms. Intracranial aneurysms can be divided into non-ruptured aneurysms and ruptured aneurysms. The vast majority of intracranial aneurysms are non-ruptured aneurysms, which generally will not rupture for life, and the annual rupture rate is only 0.05%. However, once a non-ruptured aneurysm ruptures, it will cause spontaneous subarachnoid hemorrhage and become a ruptured aneurysm. The mortality and disability rate exceeds 50%, which seriously threatens the live...
