EXPLORING THE REVERSE SURAL ARTERY FLAP IN SOFT TISSUE RECONSTRUCTION

Background: Addressing soft tissue defects in the distal lower extremity and foot remains a complex reconstructive procedure, presenting considerable challenges. These challenges underscore the necessity for locally available tissue reconstructive alternatives that offer superior solutions. The Regional Soft Tissue Augmentation Flap (RSSAF) emerges as an optimal choice, demonstrating considerable versatility at the lower leg level and serving as a viable alternative. This study aims to discuss the advantages, limitations, and potential complications associated with RSAF and to study the outcome of RSSAF in management of complex distal one third leg defects in MVJMC&RH.

Method: The study was Retrospective Observational Study and was conducted in MVJMC&RH amongst 20 patients who underwent reconstruction of distal lower extremity and foot defects with an RSSAF between June 2022 to September2023. Data concerning patient demographics, location and cause of defect, mean operation time, mean size of the defect, postoperative protocol, healing flap rate, and complications were recorded. Results The result of the Sural artery fasciocutaneous flap for the 20 cases had complete recoveries, 2 cases had partial necrosis and 2 case had wound dehiscence. A total of 4 patients suffered complications. Complication rate -20%. Overall flap survival rate was 100%.

Conclusion: The Reverse Superficial Sural Artery flap can be used as a reliable alternative to free tissue transfer in reconstruction of defects over the lower third of leg, ankle and foot to recreate a functional lower limb with comparable aesthetic results.

Recommendations: Optimizing Patient Selection: Conduct studies to refine criteria for patient selection, ensuring that RSAF is applied in cases where it is most beneficial. Enhancing Rehabilitation Protocols:Develop and refine rehabilitation protocols to improve postoperative outcomes and minimize the risk of complication.
