Correct Answer � D Explanation |
 |
Calot’s triangle, or the hepatocystic triangle, is an important anatomical region encountered during cholecystectomy. It is used to identify structures such as the cystic artery before ligation.
Boundaries of Calot’s Triangle (modern definition):
-
Medial boundary: Common hepatic duct
-
Inferior boundary: Cystic duct
-
Superior boundary: Inferior surface of the liver (or right lobe of liver)
Contents of the triangle:
-
Most commonly, the cystic artery traverses within this triangle but is not a boundary itself.
Reason to rule out other options:
A. Common hepatic duct – Forms the medial boundary of the triangle.
B. Cystic duct – Forms the inferior boundary.
C. Right lobe of liver – Forms the superior boundary.
