Hepatic Arterial Variations and Its Implication During Pancreatic Cancer Surgeries

Aberrant hepatic artery anatomy is a considerable challenge during pancreatic surgery as it warrants extreme caution for the preservation of vascular supply as well as achievement of R0 resection margin.

We reviewed the literature about the aberrant anatomical variations of the hepatic artery and its relevance during pancreatoduodenectomy and distal pancreatectomy.

Preoperative deliberation of peri-pancreatic vascular anatomy using advanced imaging methods is crucial for surgeons. At the same time, intra-operative suspicion and early identification of aberrant anatomy may help to prevent vascular injury and related complications. Yet, vascular reconstruction may be needed in many situations; several techniques like pre-operative embolization provide new options for management in specific situations.

We have provided here an overview of the anatomical variants of the hepatic artery and their implication during pancreatoduodenectomy and distal pancreatectomy.
