Insights
This study documents a rare combination of celiac and hepatobiliary arterial variations, including an aberrant right gastric artery and a missing proper hepatic artery. Understanding these unique anatomical findings is vital for surgical and radiological procedures.
Area of Science:
- Anatomy
- Vascular Anatomy
- Surgical Anatomy
Background:
- The celiac trunk and associated hepatobiliary arteries exhibit frequent anatomical variations.
- Knowledge of these variations is critical for safe surgical and radiological interventions.
Observation:
- A unique case of celiac and hepatobiliary arterial variation was observed during cadaveric dissection.
- The cystic artery originated from the gastroduodenal artery, forming a common trunk for the aberrant right gastric artery and supraduodenal artery.
- The specimen also lacked a proper hepatic artery and had an accessory right gastric artery arising from the splenic artery.
Findings:
- This represents the first documented instance of this specific combination of arterial variations.
- The aberrant right gastric artery originated from the cystic artery's common trunk.
- The accessory right gastric artery originated from the splenic artery.
Implications:
- Accurate identification of these rare anatomical variations is essential for surgeons and interventional radiologists.
- Awareness of such anomalies can prevent iatrogenic hemorrhage and biliary complications during hepatobiliary procedures.
- This case highlights the importance of detailed pre-operative imaging and anatomical knowledge.
Abstract:
The celiac trunk and hepatobiliary anatomy often display variations in origin and branching patterns. A particularly rare variant involving the cystic artery giving rise to a common trunk for the supraduodenal and an aberrant right gastric artery, with an additional accessory right gastric artery originating from the splenic artery, has not been previously documented. We report a unique variation in the branching pattern of the celiac trunk and the cystic artery revealed during routine dissection of the hepatobiliary region of a male cadaver at Louisiana State University, Health Sciences Center, Shreveport. In this case, the cystic artery originated from the gastroduodenal artery and gave rise to a common trunk of an aberrant right gastric artery and the supraduodenal artery. Additionally, the cadaver lacked a proper hepatic artery, and an additional (accessory) right gastric artery originated from the splenic artery. This report is the first documented instance of such combined variations in the celiac and hepatobiliary arterial anatomy. Recognizing potential variations in these anatomies is crucial for radiological and surgical interventions in the hepatobiliary area to avoid iatrogenic hemorrhage or biliary complications.
