摘　　要：Extrahepatic portal vein aneurysm (PVA) is very rare with only 17 previously reported cases.Methods of treatment include resection,thrombectomy,and portal venous decompression.We report herein the first case of large PVA with thrombosis which has been managed without surgical treatment over a long period.A PVA was detected in a 78-year-old woman by abdominal ultrasonography.Computed tomography revealed an aneurysm of 6 cm in a diameter in the porta hepatis.Portal venography showed obstruction of the portal vein and developed collateral vessels around the aneurysm.Since the patient had no symptoms of portal hypertension,we decided to carefully manage her clinical course without surgical treatment.At present,this patient is healthy and has developed no complications over the 5 years since leaving our hospital.This case suggests that surgical treatment is not required for PVA without portal hypertension.Extrahepatic portal vein aneurysm (PVA) is very rare with only 17 previously reported cases.
