title: Major vascular resection as part of pancreaticoduodenectomy for cancer: radiologic, intraoperative, and pathologic analysis.
abstract: Intraoperative assessment is inaccurate in defining the relationship of a pancreatic head neoplasm to adjacent vascular structures. We evaluated the ability of preoperative contrast-enhanced CT to predict the need for vascular resection during pancreaticoduodenectomy and examined the resected vessels for histologic evidence of tumor invasion. During a 7-year period, 63 patients underwent pancreaticoduodenectomy with en bloc resection of adjacent vascular structures for a presumed pancreatic head malignancy. Clinical, radiologic, operative, and pathologic data were reviewed and analyzed. Fifty-six patients underwent resection of the superior mesenteric-portal vein confluence, three patients required inferior vena cava resection, and the hepatic artery was resected and reconstructed in eight patients. The operative mortality rate was 1.6%, and the overall complication rate was 22%. CT predicted the need for resection of the superior mesenteric or portal veins in 84% of patients. Pathologic analysis revealed tumor invasion of the vein wall in 71% of resected specimens. Tumor invasion of vascular structures adjacent to the pancreas can be predicted with preoperative CT and should alert the surgeon that vascular resection may be required. Histologic evidence of tumor cell infiltration of vessel walls was present in the majority of the resected specimens.
