Polyvinyl alcohol and gelatin sponge particle embolization of splenic artery pseudoaneurysm complicating chronic alcoholic pancreatitis

Figure 1 A: Unenhanced abdominal MRI scan 5-mo ago shows varicosis of the hilum of spleen vein and there is no sign of pseudoaneurysm of the splenic artery; B: contrast-enhanced abdominal CT scan shows enhancement of pseudoaneurysm; C: anterior-posterior view of the celiac artery angiogram shows a pseudoaneurysmal sac originating from the splenic artery; D: angiogram shows 3-F SP catheter extending into more distal splenic artery through the 5-F RH catheter; E-F: splenic artery arteriograms after immediatel embolization and 5-d later show the pseudoaneurysmal sac and distal splenic artery stop growing.
