Pancreaticoduodenectomy with venous resection and reconstruction: current surgical techniques and associated postoperative imaging findings

Purpose Introduction of effective neoadjuvant therapy for pancreas cancer has resulted in complex and aggressive operations involving vasculature resection. This results in complicated postoperative CT appearance of vasculature, which in addition to high rate of recurrence makes interpretation of imaging difficult. The aim of this study was to identify patterns of postoperative appearance of portal vein-superior mesenteric vein complex (PV-SMV).
