Free-tissue transfer experience at a county hospital

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Surgical Outcomes

Background:

• Reimbursement changes have led to an increased volume of free flap procedures at county facilities.
• Over 60% of free flaps were performed in the last 4 years of the study period, indicating a recent surge in demand.
• This trend necessitated a review of the institution's experience with free-tissue transfer.

Purpose of the Study:

• To evaluate the outcomes and identify factors influencing success and failure in free flap reconstructions at a county hospital.
• To analyze the impact of patient comorbidities and wound characteristics on free flap viability.
• To determine the critical time window for intervention in cases of flap compromise.

Main Methods:

• A retrospective review of 49 patients who underwent 53 free flap procedures between 1991 and 1999.
• Analysis of patient demographics, comorbidities (smoking, diabetes, peripheral vascular disease), wound types, and surgical outcomes.
• Correlation of risk factors and wound characteristics with free flap success and failure rates.

Main Results:

• An overall success rate of 85% (45 out of 53 flaps) was achieved.
• Traumatic wounds were the most common indication for free flap reconstruction.
• Irradiated, chronic wounds demonstrated the highest failure rates.
• Delayed reexploration of compromised flaps resulted in a 0% salvage rate, with 75% of failures attributed to such delays.

Conclusions:

• Prompt recognition and emergent surgical exploration of compromised free flaps are essential for salvaging the reconstruction.
• While comorbidities like smoking and diabetes did not reliably predict failure, irradiated chronic wounds posed a significant challenge.
• Optimizing the management of flap compromise through timely intervention can significantly improve free flap success rates in county hospital settings.
