Abstract

The invention provides an aortic dissection endoluminal repair postoperative false lumen blood flow state evaluation method, which comprises the following steps of: recoding, naming and sequencing a .IMA format file in a four-dimensional blood flow magnetic resonance imaging original file, and respectively exporting anatomical information and blood flow information contained in the .IMA format file; importing exported anatomical information and blood flow information data into an MATLAB platform to be preprocessed, processing original data through an autonomous coding program, and generating an .ENCAS format file; selecting an interested target blood vessel plane needing to be processed for analysis; selecting different blood flow parameters to calculate a time-varying quantitative relation of different blood flow dynamic parameters passing through normal aorta or real and false cavities of a dissection; and comparing different hemodynamic parameters in the true cavity and the false cavity in different planes as well as difference changes at different time points in a cardiac cycle, and analyzing hemodynamic parameters and a blood flow distribution mode in the false cavity after the aortic endoluminal repair.

Description

technical field [0001] The invention relates to the technical field of endovascular repair of aortic dissection, in particular to a method for evaluating the blood flow state of a false lumen after endovascular repair of aortic dissection. Background technique [0002] Aortic dissection is a refractory major vascular disease, that is, the aortic wall is torn, and the normal single lumen becomes true and false two lumens. The false lumen can expand into a tumor and rupture, causing sudden death. The overall mortality rate is as high as 68%. Thoracic endovascular aortic repair (TEVAR) is an emerging treatment method. The principle of TEVAR treatment is to implant aortic stent-graft in the true lumen to cover the primary tear and promote false lumen thrombosis. , shrink, or even disappear, to avoid expansion and formation of dissecting aneurysms, and then rupture, bleeding and even death. The minimally invasive advantages of TEVAR are obvious, and it has rapidly developed into...
