Abstract

The invention discloses a method and device for evaluating an aortic dissection far-end crevasse plugging treatment scheme. The method comprises the steps: (1) collecting medical image data of a patient who is not subjected to a TEVAR operation, extracting a specific three-dimensional model of the patient, building a preoperative model of the patient, a plugging main tear (virtual TEVAR operation) model, and a plugging far-end crevasse (virtual far-end crevasse occlusion surgery) model for hemodynamic calculations; (2) calculating hemodynamic indexes of the patient before and after a virtual TEVAR operation and before and after a virtual far-end crevasse occlusion operation, so as to quantify the influence of the TEVAR operation and the far-end crevasse occlusion operation on hemodynamics between true and false aorta cavities; and (3) according to the hemodynamic indexes, further evaluating the surgical scheme for placing a far-end crevasse plugging device. The method and the device aim to display the blood flow state in a B-type aortic dissection by using hemodynamic indexes and provide quantitative judgment indexes for the treatment effect.

Description

technical field

[0001] The invention relates to the technical field of biomedical engineering, in particular to a method and a device for evaluating a treatment plan for blocking aortic dissection at the distal end. Background technique

[0002] With the continuous advancement of medical technology, the level of treatment of type B aortic dissection has been significantly improved, but there are still many bottlenecks. For example, for patients with type B aortic dissection with many breaches, the necessity of closure of the distal breaches and the long-term benefit of the patients after closure of the distal breaches have been paid more and more attention.

[0003] In the field of traditional medicine, doctors often judge whether to intervene based on the symptoms of patients during follow-up after TEVAR surgery and whether there is tumor-like expansion in the distal false lumen. At the same time, the most appropriate endovascular treatment method is selected according to ...
