An information processing method and device, and a readable storage medium

Abstract

An embodiment of the invention discloses an information processing method and device, and a readable storage medium. The information processing method includes: acquiring image data of computerized tomography angiography under hyperemia for coronary artery with stenosis lesion, wherein the coronary artery includes at least two coronary arterial branches with stenosis lesion; establishing an initial thee-dimensional geometric model of the coronary artery according to the image data; on the basis of the coronary arterial branches, performing stenosis repairing on the initial three-dimensional geometric model to obtain a repaired model; according to the repaired model, presettng a computational fluid dynamics model and acquiring coronary artery entrance and exit information to acquire the repaired outlet blood flow corresponding to the coronary artery branches; according to the repaired outlet blood flow, determining the bridge sequence corresponding to the coronary arterial branches anddisplaying the bridge sequence to have the coronary artery bridged according to the bridge sequence. By the arrangement, the intelligence and accuracy of the bridging are improved.

Description

technical field [0001] The present invention relates to sequential bridge technology in coronary artery bypass grafting (CABG, Coronary Artery Bypass Grafting), in particular to an information processing method and device, and a readable storage medium. Background technique [0002] According to the report of the Ministry of Health, cardiovascular disease has become the main cause of premature death among Chinese residents, and it is also the number one cause of death in the world, and coronary heart disease (referred to as coronary heart disease or coronary artery disease) is the most common one. Cardiovascular disease, which is mainly due to the deposition of cholesterol and fat in the coronary arteries (hereinafter referred to as coronary arteries), atherosclerosis in the coronary arteries causes stenosis or blockage of the vessel lumen, and the blood flow of the stenotic coronary arteries will be greatly reduced , unable to supply sufficient blood to myocardial tissue, w...

Problems solved by technology

[0003] At present, CABG is one of the most important treatment methods to solve coronary stenosis or obstruction. It uses grafted blood vessels, namely graft vessels, to establish a vascular access at the distal end of the aorta and obstructed coronary arteries, allowing the blood pumped by the heart to flow from the main artery to the coronary artery. The artery passes through the erected vascular bridge, bypasses the coronary lesion, flows to the distal end of the coronary stenosis or obstruction, and reaches the ischemic myocardium, thereby improving the ischemic state of the myocardium; CABG includes sequential bridge methods, sequential bridge The method refers to the use of a bridge vessel to bridge the entrance of the blood vessel to be connected with two or more narrow coronary arteries, and according to the distance between the two or more narrow coronary arteries and the entrance of the blood vessel to be connected, priority is given to bridging two or more narrow coronary arteries. If the distance in the vein is closer, when two or more stenotic coronary arteries correspond to similar distances, manually determine the bridging sequence of the stenotic coronary arteries, which has the problem of low intelligence and low accuracy of bridging
