critical view of safety
Also written as: CVS — Critical View of Safety
A specific anatomical view achieved during laparoscopic cholecystectomy to ensure safe identification of structures before clipping and cutting.
Full Definition
The critical view of safety is a standardized technique in laparoscopic cholecystectomy that requires visualization of three specific criteria: only two structures entering the gallbladder (cystic artery and cystic duct), clear view of the liver bed, and no other structures in Calot's triangle. This approach significantly reduces the risk of bile duct injury by ensuring proper identification of the cystic artery and duct before division.
Usage
Usage note: Often abbreviated as CVS in operative notes.
In Context
- "Critical view of safety was achieved before clipping the cystic artery and duct." — Operative report
