Post-thrombotic syndrome (also called postphlebitic syndrome) is a complication of a blood clot that forms in a deep vein. Post-thrombotic syndrome occurs because of damage to the vein caused by the blood clot (thrombosis).
Post-thrombotic syndrome can be a long-term problem that lasts for years. It can cause sores that are painful and hard to treat.
The symptoms include:
Pain, discomfort, swelling, or itching.
Brownish discoloration of the skin.
Fragile skin on the area, which bruises easily. The skin may be dry and may peel.
Compression stockings may be used to reduce swelling and relieve symptoms.
