Reconstruction of the extrahepatic portal vein after pancreatic trauma – Report of two cases

Obstruction of the extrahepatic portal vein blocks the outflow through the superior mesenteric (SMV), splenic (SV), and coronary veins (CV) and causes portal hypertension of the prehepatic type.We present two case reports of patients who developed SMV obstruction after pancreatic trauma treated by reconstruction of the extrahepatic portal vein with an autologous venous graft between the SMV and portal veins.Restoration of normal hepatopedal flow was achieved in these two cases by replacing the thrombosed segments of the retropancreatic superior mesenteric vein following pancreatic trauma.
