A 55-year-old man with postsurgical pancreatitis resulting in hematocrit drop and sanguineous output via his surgical drain. Computed tomography revealed a sizable pseudoaneurysm in the splenic artery (arrow, a ). Angiography ( b ) demonstrated significant outflow and the distal splenic artery was catheterized and coiled ( c ). Ethyl vinyl copolymer was injected to fill the pseudoaneurysm and feeding artery (arrow, d ). Final angiography was performed via the superior mesenteric artery and demonstrated occlusion of the pseudoaneurysm with downstream perfusion of the spleen (arrow, e ) via collaterals.
