Variations in origin of inferior pancreaticoduodenal artery

Abstract

Coeliac trunk and Superior Mesenteric arteries are very much susceptible to variations and were described by Tandler in 1904. Abdominal aorta branches are classified as single double or visceral parietal. Double visceral branches are middle suprarenal, renal and testicular arteries and single visceral branches are coeliac trunk, superior mesenteric and inferior mesenteric arteries. Materials and Methods: After obtaining ethical committee approval, we observed the origin, course and branching pattern of pancreatico duodenal arteries in 50 cadavers kept for dissection from 2019-2022 in Rohilkand Medical College and Hospital and Ayaan Institute of Medical Sciences. Results: In a male cadaver aged approximately 60 years, we observed that inferior pancreatico duodenal artery is absent. In another male cadaver aged about 70 years, we observed an additional inferior pancreatico duodenal artery. In remaining specimens, we observed the branching pattern very much normal.

The arterial supply of pancreas: clinical and anatomical correlation

“…Kotapalli et al observed an additional IPDA which originated from 2nd jejunal branch of SMA (7). In our study too, the accessory IPDA was present but it was seen to be originating from SMA.…”

“…Pro ciency in the arterial branches and their variant anatomy is utmost required to avert complications like ischemia, necrosis of duodenum and head of pancreas during surgical interventions. (5)(6)(7) Expertise in the variant anatomy will enhance the readiness for sudden modi cations which may be required in arterial embolization procedures intraoperatively.…”
