Migrating superficial venous thrombosis

Venous thrombosis can occur with migrating superficial venous thrombosis, which usually involves the large saphenous vein or small saphenous vein or its branch, which mostly occurs on the basis of varicose veins. The main feature is pain at the thrombus formation site, and there is a red, low-temperature cord in the superficial vein, tenderness, and swelling around. Its emboli are not easy to fall off and generally do not cause pulmonary embolism. In addition, migrating superficial venous thrombosis is often a suggestive symptom of cancer.
