Embolisms are rare with which venous condition?

• A. Deep vein thrombosis
• B. Caput Medusa
• C. Varicose veins
• D. Spider veins

Answer: (C)

Emboli in the venous system most often come from clots in the deep veins of the legs, and then travel to the lungs as pulmonary emboli. Varicose veins are dilated superficial veins with valve incompetence; while they can develop clots, those clots are far less likely to detach and propagate into the deep venous system and then to the lungs. That makes embolisms rare with varicose veins. In contrast, deep vein thrombosis directly involves the deeper venous circulation and is a well-known source of significant embolic risk. Caput medusae reflects portal-systemic collateral circulation from portal hypertension, not a typical route for systemic venous emboli, and spider veins are even smaller superficial vessels with negligible embolic risk.
