Summary
The anterolateral thigh (ALT) flow-through flap is a versatile surgical technique for reconstructing complex extremity defects, offering simultaneous arterial and soft tissue repair. This method demonstrates high success rates in restoring vascular continuity and coverage for various injuries.
Area of Science:
- Plastic Surgery
- Microsurgery
- Reconstructive Surgery
Background:
- Flow-through flaps are established for complex extremity reconstruction, enabling simultaneous arterial repair and soft tissue coverage.
- The anterolateral thigh (ALT) flow-through flap is explored for its versatility in addressing extensive limb defects.
Purpose of the Study:
- To demonstrate the comprehensive role and versatility of the anterolateral thigh (ALT) flow-through flap in reconstructing complex extremity defects.
- To evaluate the efficacy of ALT flow-through flaps in various reconstructive scenarios, including trauma and oncological resections.
Main Methods:
- Retrospective analysis of 87 patients undergoing reconstructive surgery using ALT flow-through flaps between February 2011 and March 2017.
- The technique was applied for bridging arterial gaps, preserving vessel integrity, and combined soft tissue and vascular reconstruction.
Main Results:
- 83 of 87 flaps were used for vascular reconstruction, with a high survival rate (84 flaps) post-operatively.
- Minor complications included venous congestion requiring reexploration (3 patients), flap necrosis (3 patients), and donor/recipient site issues (5 patients each).
Conclusions:
- The ALT flow-through flap is a highly versatile method for complex extremity reconstruction, addressing multiple clinical needs.
- Its application extends beyond simple defect coverage to include critical vascular reconstruction and preservation.
