Thrombosis occurs when a blood clot, also known as a thrombus, forms in a blood vessel and stops blood from easily flowing within your circulatory system. Different types of thrombosis are classified based on where the blood clot forms in the body.
- Superficial thrombosis – refers to a blood clot in a vein near the skin
- Arterial thrombosis – when a blood clot has developed in an artery
- Deep vein thrombosis – occurs when a blood clot forms in a major vein, usually in the leg
- Pulmonary embolism – occurs when a blood clot forms in vessels in the lung
