Inflammation of superficial vein – associated with thrombus formation
20% due to deep vein thrombosis
Swelling of limb, pitting oedema, cyanosis. May have a linear shaped area of erythema.
May feel vein as a “tender cord” – warm to touch. Elevation of limb does not change clinical features. Not associated with oedema
Two main types:
Superficial benign thrombophlebitis – more common; usually long or small saphenous veins; can be recurrent as part of primary varicose veins
Superficial migratory thrombophlebitis – not in main superficial veins; can recede and develop elsewhere or may persist; occurs in association with Thomboangiitis Obliterans
