Abstract

Pancreatoduodenectomy (PD) also known as Whipple procedure is done for malignant lesions involving the distal CBD, duodenum, ampulla and pancreatic head. In the absence of peritoneal and distant metastases, resectability of the lesion is mainly determined by the relationship of the lesion with the vascular structures in the vicinity. Vascular variations of the celiac artery branches are common and PD, a complex surgical procedure, becomes more challenging if the vascular variations are present. In borderline resectable lesions advances in neoadjuvant therapies and refined surgical techniques are pushing the boundaries of resection. Extended PD is done in borderline resectable lesions when resection and reconstruction of portal vein involved by the primary mass and dissection of extended lymph nodal stations are intended. In this era where more borderline cases are undergoing surgery, it is essential for the radiologist to understand the procedure and the implications of variations in vascular anatomy. Though there are many radiology literatures available on the diagnostic and resectability criteria related to normal vessel anatomy there are very few on the importance of the variant arterial anatomy. The purpose of this review is to familiarize the readers with these variant vessels which can help the surgeons in their intraoperative identification and consequently improve surgical outcomes.
