A venous thrombosis is a condition in which a thrombus (blood clot) forms within a vein. Superficial venous thrombosis, as the name suggest is the formation of a thrombus in superficial veins. It can cause discomfort but generally do not cause serious consequences, unlike the deep venous thrombosis (DVTs) that form in the deep veins of the legs or in the pelvic veins. Many causes can predispose the body to venous thrombosis formation, all of which affect the traditional factors of Virchow triad of thrombosis; blood stasis, vessels wall defect and hypercoagulability^[1].

• Bones (particularly hip and jaw)
• Brachial vein
• Cerebral venous sinus thrombosis
• Mesenteric vein
• Paget-Schroetter disease (upper extremity vein)
• Placental vein
• Pulmonary vein
• Renal vein thrombosis
• Retinal vein
• Superior vena cava syndrome
• Thoracic outlet syndrome (the cause of most subclavian vein thrombosis unrelated to trauma)
• Hepatic vein thrombosis (Budd-chiari syndrome)
• Deep venous thrombosis (with or without pulmonary embolism; together classified as venous thromboembolism/VTE)
• Portal vein thrombosis
