Abstract

By employing three-dimensional computed tomography (CT) for portography, we analyzed the portal vein changes during the initial stage after a pancreaticoduodenectomy (PD), which seemed to affect postoperative complications. Four patients underwent PD without portal vein reconstruction with a standard radical lymph node dissection for cancer of the pancreaticoduodenal area. A total of 140 ml of contrast medium was intravenously injected at 2.5 ml/s, and imaging was started after 65 s with a Hitachi W-2000 CT scanner. Three-dimensional portal vein images were then reconstructed by the Voxel Transmission method. Three-dimensional CT showed portal stenosis in our all patients from the first to the third week after PD. In three of the patients, stenosis disappeared by week 7,8, or 15, respectively, without the formation of a bypass. In three patients, portal vein stenosis was severe while in one patient, it was mild. Severe complications such as gastrointestinal hemorrhaging and hepatic abscess occurred in two patients with severe portal stenosis. The onset of portal stenosis might therefore affect postoperative complications after PD.
