Summary
Free-tissue transfers effectively reconstruct radiation-induced injuries, achieving a 97% success rate. However, complications are common, and using irradiated vessels increases thrombosis risk.
Area of Science:
- Plastic Surgery
- Oncology
- Reconstructive Surgery
Background:
- Radiation therapy can cause complex injuries requiring reconstructive surgery.
- Free-tissue transfer is a potential method for addressing these defects.
Purpose of the Study:
- To evaluate the efficacy and outcomes of free-tissue transfers for complex radiation-induced injuries.
Main Methods:
- Retrospective review of 30 patients (33 free flaps) treated between 1988 and 1995.
- Analysis of defect locations, time between irradiation and reconstruction, flap success rates, complications, and follow-up data.
Main Results:
- Free-tissue transfer achieved 97% success in reconstruction.
- Overall complication rate was 40%, with pedicle thrombosis occurring in 3 cases.
- Head and neck defects were most common (n=23).
Conclusions:
- Free-tissue transfer is a viable option for healing radiation-induced wounds.
- Complications are frequent, and using irradiated vessels carries an increased risk of thrombosis.
