Upper extremity deep vein thrombosis

Axillary-subclavian venous thrombosis is a group of syndromes mainly manifested in upper limb swelling, pain, bruising of the skin, and dysfunction. In 1949, Hughes first described the disease as: "Healthy adults with acute upper extremity venous occlusion of varying severity without clear etiology and pathology are called Paget-Schroetter syndrome." In the past, the disease was considered to be a This is an idiopathic and self-limiting disease that has no serious effect on the body. The upper limbs and shoulder collateral circulation are abundant, even if the main vein is blocked, it will not cause serious blood reflux disorders. The fibrinolytic activity ratio of upper limb vein endothelial cells The lower extremity veins are 4 times higher and easily recanalize after thrombosis, so there is no need to pay too much attention to the treatment. Guided by this misconception, many patients develop sequelae of thrombosis due to inactive treatment. Comprehensive literature reports that the incidence of sequelae accounts for 25% to 74% of all patients, and patients with pulmonary embolism have also been reported from time to time. In recent years, after in-depth research, a new understanding of the disease has been achieved, and the treatment effect has been improved.
