Pancreaticoduodenectomy (PD) is the procedure of choice in patients with tumors of pancreatic head or periampullary region. Hepatic artery anatomic variants (HAav) are frequently encountered during PD.
To evaluate the incidence of HAav in a series of PDs and their consequence on technical tailoring and outcome.
Forty-five patients with HAav were identified in a consecutive series of 140 PDs for periampullary and pancreatic head tumors performed between January 1, 2007 and December 31, 2015. The groups with or without HAav were compared in terms of operative approach, complications and survival.
All patients underwent Whipple procedure, with right posterior approach for those having HAav. HAav was spared without damage in 41 cases. Four patients in whom the HAav were either sacrificed (2) or damaged (2) required arterial reconstruction.
HAav are frequently encountered during PD. Its safeguarding is mandatory but in malignancy it can be damaged or sacrificed, hence arterial reconstruction is required. HAav have no negative impact on surgical morbidity and outcome.
