stagnation of venous blood flow
Introduction
Introduction Venous blood flow stagnation: thrombophlebitis is a venous vascular disease characterized by acute non-suppurative phlebitis secondary to intracavitary thrombosis. The skin of the superficial venous area is red and swollen, spontaneously involved in pain, and can be touched. Painful strips or nodules, venous blood flow is slow.
Cause
Cause
1 surgery: especially in orthopedics, thoracic cavity, abdominal cavity and genitourinary surgery.
2 tumors: pancreas, lung, gonads, breast and urinary tract malignancies.
3 trauma: especially the spine, pelvis and lower limb fractures.
4 long-term bed rest: such as acute myocardial infarction, stroke, after surgery.
5 pregnancy, the role of estrogen;
6 hypercoagulable state: lack of antithrombin III, protein C or S protein, circulating lupus anticoagulant, myeloproliferative disease, abnormal fibrinemia, diffuse intravascular coagulation (DIC).
7 venous inflammation and intravenous intervention diagnosis or treatment lead to venous injury.

The main clinical manifestations are red, swollen, painful and obvious tenderness along the vein, and can reach the cord-like vein; systemic response is rare. The pressure in the veins of the lower extremities increases. Venous angiography shows the location and extent of the blockage.
Diagnosis
Differential diagnosis
Superficial venous thrombosis: Because superficial venous thrombosis does not cause pulmonary embolism and chronic venous insufficiency, it is far less clinically important than deep vein thrombosis. This disease is associated with prolonged or repeated intravenous infusion, especially when a more irritating drug is administered. It can also occur in varicose veins. The vein wall often has different degrees of hot lesions, and the intracavitary thrombosis often adheres to the wall of the tube and is not easy to fall off. Due to the connection of traffic branches, deep and superficial vein thrombosis can sometimes be formed at the same time.
Deep vein thrombosis: mainly caused by blood foreign body and hypercoagulable state, so the thrombus and the thrombus wall only have slight adhesion, easy to fall off into an embolus and form a pulmonary embolism while deep vein thrombosis causes blood reflux to be significantly affected. Causes distal tissue edema and hypoxia, forming chronic venous insufficiency syndrome.
