Superficial thrombophlebitis

Superficial thrombophlebitis

Overview

Superficial thrombophlebitis is an inflammation of a vein just below the surface of the skin, which results from a blood clot. This condition may occur after recently using an IV line, or after trauma to the vein. Some symptoms can include pain and tenderness along the vein and hardening and feeling cord-like. Superficial thrombophlebitis is usually a benign and short-term condition. Symptoms generally subside in 1 to 2 weeks, but hardness of the vein may remain for much longer.
