Presence of Cystic Artery in the Calot’s Triangle and Its Relation with Common Hepatic Duct – a Postmortem Study

Abstract

Results: It was found from the result of the present study that out of 60 cases cystic artery was found as a content of Calot's triangle in 58 (96.65%) cases. Regarding the relations of the cystic artery, out of 60 specimens, in 54 cases (90%) cystic arteries were observed to pass behind the common hepatic duct. In four cases (6.67%) cystic artery were found crossing over the common hepatic duct and in two cases (3.33%), cystic artery were found crossing below the cystic duct.In one cases, branches of cystic artery (superficial and deep branch) was found. In every specimen a Calot's node was found within the Calot's triangle. Discussions:The result of the present study was compared with other workers. Though many of the workers found similar results regarding the course of the cystic artery through the Calot' triangle but some workers found higher number of cystic artery passing outside the triangle. Also higher percentage of cystic artery passing over the common hepatic duct was found by many workers than the present study.

Study of variations in origin and course of cystic artery in relation to Calot’s triangle

“…The cystic artery was found inside the calots triangle ranging from 65.0% to 100.0% 5,7,13,14,20,21,23,25 as noted by different investigator where as result of the present study that is 96.67% and it is found to be similar to studies of Desliva 23 and Rahman. 20 As per study of previous authors, the cystic artery was found outside the calot's triangle ranging from 0.0% to 35.0% 7,13,14,20,21,25 as described where as in the present study we recorded as 3.3% (in 1 case).…”

Morphological Parameters of Gallbladder are Correlated with Age

“…Liver and biliary diseases are the most common health problem throughout the world as well as in Bangladesh. The most common biliary diseases are cholelithiasis 5 . Gallstones afflict 10% to 20% of adult populations in developed countries.…”

“…It is estimated that over 20,000,000 persons in the United States have gallstones (Crawford, 2005). Up to 25% of all Bangladeshi people have gallstones 5 . Cholecystitis is associated with cholelithiasis in 95% cases (Crawford, 2005) 6 .…”

“…A traditional cholecystectomy is most commonly performed from the infundibulum to the fundus as no medical treatment is still available. Now a day's laparoscopic cholecystectomy replaces the open surgical method 5 . During operation surgeons have to identify the cystic duct and cystic artery properly before ligation.…”

“…During operation surgeons have to identify the cystic duct and cystic artery properly before ligation. Uncontrolled bleeding from the cystic artery and its branches is a serious problem that may, increase the risk of intraoperative lesions to vital vascular and biliary structures 5 . The performance of a safe cholecystectomy depends on thorough knowledge about the normal anatomy and anatomical variations that may contribute to the occurrence of major postoperative complications.…”
