Background
Reverse sural flap (RSF) is commonly used for soft tissue reconstruction of distal leg and heel defects. The classic method of flap transfer is the single-staged cutaneous islanded reverse sural flap (SS-RSF). This method is associated with variable flap complications notably the venous congestion. The other form of flap transfer is the two-stage reverse sural flap (TS-RSF), in which the pedicle of the flap is exteriorized in the first stage. Flap division and re-inset are done in the second stage. The aim of this paper is to review the flap outcomes and complications among the SS-RSF and TS-RSF reconstruction of soft tissue defects in the distal leg and heel.
Methods
This is a retrospective chart review of RSF being operated in a tertiary care hospital. The duration of study was 1.5 years. Twelve RSFs (6 SS-RSF, 6 TS-RSF) were done for soft tissue defects in the distal leg and heel. Wounds of various etiologies (traumatic, chronic, non-healing ulcers) were reviewed. Trauma was the most common etiology with 8 out of 12 (66.7%) patients. Large wounds, donor site damage and patients with peripheral vascular disease were excluded from the study.
Results
Five out of six (83.3%) of TS-RSF healed uneventfully. However, 3 out of 6 (50%) of SS-RSF had partial flap necrosis. All complicated flaps healed well subsequently. No donor site complication was found in any of our patients.
Conclusion
Pedicle exteriorization in TS-RSF eliminates the element of venous congestion and eventually flaps necrosis. Less technical expertise and minimal morbidity are additional advantages of TS-RSF.
Level of evidence
Level IV, therapeutic study.
