What is the main purpose of a transfixation ligature on a large vascular pedicle?
Correct answer: C. Prevent ligature slippage
- A. Enlarge the surgical incision
- B. Reduce tissue inflammation
- C. Prevent ligature slippage
- D. Speed epithelial migration
Explanation
A transfixation ligature passes through the pedicle and anchors the ligature, reducing the risk of slipping from a large or thick vascular pedicle. It does not primarily alter inflammation or wound epithelialisation.
