Type B aortic dissection postoperative risk prediction method and device, and electronic device

Abstract

The embodiments of the invention provide a type B aortic dissection postoperative risk prediction method and device, and an electronic device, and relates to the technical field of medical images. Thetype B aortic dissection postoperative risk prediction method comprises the steps that firstly, a plurality of cases of preoperative three-dimensional angiography images are obtained, and all cases of the three-dimensional angiography images are pretreated to obtain a to-be-treated data set, wherein the to-be-treated data set comprises blood vessel true lumen information and blood vessel false lumen information; then the blood vessel true lumen information and the blood vessel false lumen information are subjected to vector analysis to obtain various image omics feature information, and the various image omics feature information is subjected to dimensionality reduction treatment and linear fitting to obtain risk factor variables; and finally, a risk predicting model is constructed according to the risk factor variables and a preset clinical lesion type. In this way, the risk probability of postoperative complications can be obtained, and thus patient safety is ensured.

Description

technical field [0001] The present application relates to the field of medical imaging, in particular, to a risk prediction method, device and electronic equipment for type B aortic dissection. Background technique [0002] Type B aortic dissection (TBAD) is due to the tear of the aortic intima, the blood flow enters the media of the aortic wall through the tear, separates the media, and expands along the long axis of the aorta to form true and false Two chambers. [0003] At present, Thoracic Endovascular Aortic Repair (TEVAR) is mainly used to treat type B aortic dissection. The basic principle is to use a covered stent to cover the first opening, isolate the blood supply to the false lumen, restore the blood supply to the true lumen, expect complete thrombosis in the false lumen, and finally complete good arterial remodeling. However, TEVAR treatment is not done once and for all, and its postoperative complications are often accompanied by some complications, such as th...
