Stent placement is effective on both postoperative hepatic arterial pseudoaneurysm and subsequent portal vein stricture: A case report

Figure 1 A: A severe stricture of a narrow segment in the proper hepatic artery and a bulging at the stump of the gastroduodenal artery were seen. An arrow indicates a stricture; B: The stent-graft for an angioplasty was introduced through the stenotic segment to secure the hepatopetal arterial flow. Arrow heads indicate the stent-graft placed in the hepatic artery; C: After the stenting, embolization of the pseudoaneurysm was attempted to stop the inflow into the pseudoaneurysmal lumen using microcoils. An arrow head indicates microcoils placed in the pseudoaneurysmal lumen; D: The patency of the hepatic artery and disappearance of the pseudoaneurysm were confirmed by arteriography 8 d after the treatment.
