Foregut Artery Meets Hindgut Territory: A Unique Case of Splenic Artery Supplying Left Colic Flexure with Presence of Pga and Dpa

Abstract

Background: Coeliac trunk is the artery of foregut. The present case report is a unique constellation of vascular variations where intrapancreatic splenic artery with its branch supplying to the left colic flexure, presence of dorsal pancreatic artery arising from the common hepatic artery and the presence of posterior gastric artery originating from the splenic artery. This finding is unique as the splenic branch of coeliac trunk which is the artery of foregut is supplying the left colic flexure which is derivative of hindgut. Combination of such different vascular branching patterns in a single case is very rare. The knowledge of such variations are clinically significant to surgeons and radiologists for gastric cancer surgeries like total or subtotal gastrectomy, bariatric surgeries, pancreatic transplantations, gastric artery aneurysms, pancreatico-duodenectomy and surgery for insulinoma.
