Aberrant hepatic arteries running through pancreatic parenchyma encountered during pancreatoduodenectomy: Two rare case reports and strategies for surgical treatment.

ABSTRACT:

Background

Aberrant hepatic arteries (HAs) encountered during pancreatoduodenectomy are difficult to manage.

Mehtods

Two cases with rare types of aberrant HA running through the pancreatic parenchyma were reviewed.

Results

The first case, a 68-year-old man, was admitted with obstructive jaundice. A tumor of the pancreatic head and aberrant HAs were suspected on computed tomography (CT) scan. At laparotomy, a new variation was identified; namely, 2 aberrant arteries-a right replaced HA and middle HA (RMHA) that both originated from the superior mesenteric artery (SMA) and ran via intrapancreatic paths posterior and anterior to the pancreatic head, respectively. Branches of the RMHA to the pancreas were ligated and severed and the trunk preserved. The RMHA was mistakenl
