Summary
The sartorius muscle flap, pedicled on the saphenous artery, demonstrates reliable retrograde blood supply for reconstructive surgery. This versatile flap is effective for covering defects around the knee and lower leg.
Area of Science:
- Anatomy
- Vascular Surgery
- Reconstructive Surgery
Background:
- The sartorius muscle is a superficial thigh muscle.
- Its distal vascular supply is crucial for reconstructive procedures.
Purpose of the Study:
- To investigate the vascular anatomy of the distal sartorius muscle.
- To define patterns of retrograde circulation for flap viability.
Main Methods:
- Dissection of 37 limbs under magnification.
- Vascular injection with black ink and latex.
- Analysis of retrograde perfusion via saphenous artery anastomoses.
Main Results:
- Three distinct vascular patterns of the distal sartorius muscle were identified.
- The saphenous artery (SA) demonstrated reliable retrograde perfusion.
- The flap is suitable for knee, lower leg, and amputation stump coverage.
Conclusions:
- The sartorius muscle flap, pedicled on the SA, is a viable option for reconstruction.
- Retrograde circulation ensures flap survival.
- The procedure yields excellent functional and cosmetic outcomes without defects.
