Distal arterial splenic embolization via collaterals: report of two cases.

摘要

Two patients were treated for bleeding gastric varices, developed due to splenic vein occlusion. In one patient with occlusion of the main splenic artery, splenic embolization performed via collaterals facilitated open splenectomy with minimal blood loss. In another patient, bleeding from the gastric varices stopped after partial arterial splenic embolization performed via the accessory left gastric and inferior phrenic arteries. No complications were encountered.
