Summary

The authors report a case of a 75-year-old woman who was seen about 5 years ago and found to have asymptomatic gallstone and extrahepatic portal vein aneurysm (PVA) adjacent to the gallbladder. Further investigations revealed no evidence of cirrhosis. A follow-up ultrasound revealed that the PVA increased in diameter from 20 to 25 mm over 5 years and surgical intervention was recommended. Cholecystectomy and omental wrapping around PVA were performed. Postoperative follow-up investigations for 3 years revealed no increases in PVA diameter. Although PVA is clinically rare, the authors believe that their case report presents an overview of related literature, discusses indications for surgery in PVA and describes their surgical method for managing PVA.
