Abstract:

Objective To investigate the anatomic variations of cystic artery(CA), so as to provide morphological basis for laparoscopic cholecystectomy(LC). Methods A total of 45 cadavers were randomly collected. Arteries including abdominal aorta, celiac artery, superior mesenteric artery and their branches were dissected. The origin, course and the relations of CA to the surrounding structures were observed and statistically analyzed. Results According to the relations of CA to the Calot’s triangle, the CAs in this study could be divided into 4 types: Type I  CA within Calot’s triangle (n=35,77.8%),including one CA(n=31,68.9%) and double CAs(n=4,8.9%); Type II  CA outside Calot’s triangle(n=2, 15.6%); Type III  compound type, with at least one CA within Calot’s triangle and others beyond it(n=2,4.4 %); Type Ⅳ CA  within atypical Calot’s triangle(n=1, 2.2% ). Conclusion Based on the relations of CA to the Calot’s triangle, CA can be divided into four types, implying the origin and the course of CA are so complicated and unexpected in some degree that surgeons should pay close attention to these unpredictable variations to avoid occurrence of complications during or after LC.
