Successful Treatment of Giant Common and Proper Hepatic Artery Aneurysm Complicating Autosomal Dominant Polycystic Kidney Disease.

Hepatic artery aneurysms (HAAs) complicating autosomal dominant polycystic kidney disease (ADPKD) are extremely rare. On account of the large number of renal cysts in ADPKD, ingenuity is required to safely perform surgery for HAA. Here, we present the case of a 60-year-old man with a common and proper HAA of >60 mm complicated with ADPKD. In this patient, difficulty in maintaining the field of view was expected during surgery. Hence, we performed a hybrid approach with celiac-to-right hepatic artery bypass by puncturing the femoral artery and cannulating the splenic artery to allow celiac-splenic artery balloon occlusion in case of rupture. More than 5 years postoperatively, the graft is patent without intervention.
