Fig. 3. Embolization with the isolation technique for bleeding after gastrectomy. (A) CA angiography shows no extravasation and pseudoaneurysm (arrow, SPA stump). (B) SMA angiography shows HAs due to the hepatopetal flow. (C) A 5-Fr balloon catheter is placed at the distal portion of the common HA to prevent distal migration (arrow). (D) Another 5-Fr balloon catheter is placed at the CA to prevent proximal migration. Obvious extravasation is visualized along with the drain tube (arrowheads). (E) Metallic coils are deployed from the distal to the proximal part of the bleeding portion including the SPA stump (arrowheads). (F) SMA angiography shows the patent HAs. CA, celiac artery; SPA, splenic artery; SMA, superior mesenteric artery; HA, hepatic artery.
