Abstract
A 71-year-old man was admitted to our department in order to undergo an elective laparoscopic cholecystectomy. During the dissection of Callot’s triangle we recognize the cystic duct and cystic artery relatively with ease. Immediately after the right hepatic artery we observed a bifurcation of another artery, originated directly from the cystic trunk. The suvramentioned artery was preserved for 7-8 cm length approximately, until its entrance to the hepatic parenchyma. No other vascular or biliary abnormalities were occurred. Then, cystic duct and cystic artery clipped and divided. The patient recovered without any complications. CT imaging findings which followed the first postoperative day confirmed our assumption. To our knowledge, this is the first case where an aberrant right hepatic artery originates directly after the bifurcation of right hepatic artery and cystic artery.
Conclusions:
Given the large number of laparoscopic cholecystectomies performed annually, better knowledge of anatomic variation of cystic artery may prevent arterial and potentially bile duct injury, particularly for those patients with unusual anatomy of the Callot’s triangle.
Conclusions:
