Abdominal aortic multiple appendage thrombosis is relatively dangerous, and is related to local wall damage and abnormal coagulation function, which can easily cause tissue ischemia and even cerebral infarction. The main risk factors of abdominal aortic polyclonal thrombosis include the following two aspects, which are lumen narrowing and thrombus dislodgement. 1. Lumen narrowing: a large part of epiphyseal thrombosis is caused by damage to the lumen wall, after which thrombus gradually forms and accumulates in the corresponding area, which may lead to obvious narrowing of the local lumen, further causing abnormalities in blood supply and ischemic episodes in organs. 2. Thrombus dislodgement: Abnormal coagulation function in the body leads to multiple thrombus formation, and part of the thrombus may be dislodged along with the blood flow, and further enter into the circulatory system, causing local embolism, which is prone to pulmonary embolism and cerebral infarction. The discovery of abdominal aortic appendage thrombosis needs to be promptly admitted to the hospital, under the guidance of the clinician to carry out standardized treatment, to avoid the danger.
