title: Reconstruction of the main portal vein for a large saccular aneurysm.
abstract: BACKGROUND
  A large aneurysm of the main portal vein is rare, and the appropriate surgical procedure is uncertain. Reconstruction of a main portal vein affected by a large saccular aneurysm is described.
  
  
  METHODS
  Abdominal pain led to the diagnosis of a large saccular aneurysm of the main portal vein in a 58-year-old woman who had undergone cholecystectomy 10 years earlier. At laparotomy a dorsolateral approach to the hepatoduodenal ligament was performed with no attempt at extensive separate exposure of the anatomical structures in the hepatoduodenal ligament, so as to avoid the devascularisation of the common hepatic duct and additional weakening of the portal vein wall. The aneurysm was longitudinally incised, and the portal vein was reconstructed from the walls of the aneurysm with a longitudinal running suture. The rest of the aneurysmal wall was wrapped around the portal vein, leaving it normal in size and contour. Recovery was uneventful. Follow-up CT scan showed a patent portal vein in the region of the former aneurysm.
  
  
  CONCLUSIONS
  Large saccular aneurysms can rupture, bleed and cause death. The potential hazards of manipulation of large portal vein aneurysms are negligible in comparison with the possible complications of the aneurysm itself. In our opinion the ease with which the main portal vein was dissected and reconstructed make an elective operation in such cases a reasonable approach.
