Blocked veins can be caused by superficial phlebitis, deep vein thrombosis and so on. You should go to the hospital in time to find out the cause of the problem.
1. Superficial phlebitis: Superficial phlebitis is a thrombotic inflammation that occurs in the superficial veins of the human body, which can block the superficial veins. The main symptoms are redness, swelling, pain and burning along the superficial veins. It can be treated with medications such as ibuprofen, celecoxib, and surgical procedures such as high saphenous vein ligation and stripping.
2. Deep vein thrombosis: Deep vein thrombosis is a disorder of venous return caused by abnormal clotting of blood in the deep veins, which can block the deep vein vessels. The main symptoms include swelling and pain in the lower limbs, which can be treated by anticoagulation, thrombolysis, vascular intervention, and surgery (e.g., surgical thrombectomy).
In addition, various diseases, such as benign and malignant tumors, inflammation, etc., which cause pressure on the veins, can also cause blockage. Trauma, such as prolonged tourniquet ligation, can also cause venous obstruction.
It is recommended that patients with blocked veins should go to the hospital in time for an examination to determine the cause of the problem, and be treated under the guidance of a doctor.
