Through which layer, between the gallbladder and the liver, does the deep branch of the cystic artery run?

Introduction: During laparoscopic cholecystectomy, an enlarged field of vision increases safety and precision, but surgeons often encounter bleeding that can cause difficulties. It is important to prevent and control arterial bleeding from Calot's triangle and the liver bed that results from injury to the deep branch of the cystic artery (DBCA). However, no previous reports have mentioned the layer between the gallbladder and liver through which the DBCA runs.
