Use of expanded reverse sural artery flap in lower extremity reconstruction
Case series published in J Foot Ankle Surg (2011)
Abstract
Coverage of defects of the distal third portion of the leg and foot remains a challenge for surgeons. The difficulty results from the limited mobility and availability of the overlying skin, the weight-bearing requirements, and the relatively poor circulation of the skin. From January 2008 to December 2009, 10 patients had defects of the foot and ankle covered using the 2-stage expanded reverse sural flap. Of these 10 patients, 6 had at least 1 risk factor for compromised wound healing, such as diabetes mellitus, peripheral arterial disease, venous insufficiency, tobacco smoking, or age older than 40 years. Flap necrosis was observed in only 1 patient (10%). Venous congestion was noted in 2 patients (20%) by the third postoperative day, 1 of whom responded to postural elevation of the extremity and 1 to medicinal leech therapy. Although it is a 2-stage procedure that requires wound dressing during the expansion, we strongly suggest the use of the expanded reverse sural flap for defects too large to be primarily closed, especially in patients older than 40 years with risk factors such as diabetes mellitus, peripheral arterial disease, or venous insufficiency.

Summary
Between January 2008 and December 2009, ten patients with foot and ankle defects underwent a two-stage expanded reverse sural flap reconstruction; flap necrosis occurred in one and venous congestion in two, with one case resolving after elevation and another after medicinal leech therapy.
Why This Matters for Hirudotherapy
This 2-stage expanded reverse sural flap series in 10 patients with distal-leg/foot defects reported flap necrosis in 1 patient and venous congestion in 2 by the third postoperative day, one of whom was managed with medicinal leech therapy (the other resolved with postural elevation). For hirudotherapy, it documents a real-world clinical role for medicinal leeches as a salvage option for venous congestion in a compromised flap, consistent with the established use of leeches to decongest venous-insufficient tissue. Caveat: this is a small single-center surgical case series in which leeching was a single ancillary decongestion measure in one patient, not a controlled comparison, so it illustrates use rather than measures effectiveness.
