OBJECTIVES: A 38 year old woman presented with epigastric abdominal pain and was found on CT imaging of the abdomen and pelvis to have a 4.5 cm retropancreatic portal vein aneurysm. She had no history of trauma, portal hypertension, or intrinsic liver disease.
METHODS: Due to the significant size of the aneurysm and no other explanation for her abdominal pain, the patient was prepared for surgical repair of the aneurysm.
RESULTS: Via a midline laparotomy incision, the lesser sac of the abdomen was entered, and the pancreas was mobilized in a cepahlad direction to allow exposure of the retropancreatic portal vein. The portal vein aneurysm was excised and a patch repair was performed with a bovine pericardial patch. Her post-operative course was unremarkable.
CONCLUSIONS: Portal vein aneurysms are a rare entity that may cause pain or rupture. Surgical repair of a retropancreatic portal vein aneurysm may be safely performed while preserving the pancreas.
