Major vascular resection performed at the time of pancreaticoduodenectomy (PD) for adenocarcinoma remains controversial. We analyzed all patients who underwent vascular resection (VR) at the time of PD for any histology at a single institution between 1990 and 2002. Preoperative imaging criteria for PD included the absence of tumor extension to the celiac axis or superior mesenteric artery (SMA). Tangential or segmental resection of the superior mesenteric or portal veins was performed when the tumor could not be separated from the vein. As a separate analysis, all patients who underwent PD with VR for pancreatic adenocarcinoma were compared to all patients who underwent standard PD for pancreatic adenocarcinoma. A total of 141 patients underwent VR with PD. Superior mesenteric-portal vein resections included tangential resection with vein patch (n=36), segmental resection with primary anastomosis (n=35), and segmental resection with autologous interposition graft (n=55). Hepatic arterial resections were performed in 10 patients, and resections of the anterior surface of the inferior vena cava were performed in 5 patients. PD was performed for pancreatic adenocarcinoma in 291 patients; standard PD was performed in 181 and VR in 110. Median survival was 23.4 months in the group that required VR and 26.5 months in the group that underwent standard PD (P=0.177). A Cox proportional hazards model was constructed to analyze the effects of potential prognostic factors (VR, tumor size, T stage, N status, margin status) on survival. The need for VR had no impact on survival duration. In conclusion, properly selected patients with adenocarcinoma of the pancreatic head who require VR have a median survival of approximately 2 years, which does not differ from those who undergo standard PD and is superior to historical patients believed to have locally advanced disease treated nonoperatively.
