Successful Use of WALANT in Local and Regional Soft Tissue Flaps: A Case Series

Background: The wide awake local anesthesia no tourniquet (WALANT) technique has been proven to be safe and effective for upper extremity surgery. WALANT does not require extensive medical clearance and allows for intraoperative assessment of range of motion. Additionally, it is frequently associated with lower costs and less postoperative pain when compared with traditional methods of anesthesia. Despite its expanded use for hand procedures, there are sparse data to support the use of WALANT in local and regional soft tissue flaps. Methods: A retrospective review was performed. Twenty-one patients who underwent a local or regional soft tissue flap surgery using the WALANT technique from February 2, 2018 to February 25, 2022 were included in our analysis. Results: Overall, one Louvre flap, two posterior tibial artery perforator propeller flaps, two reverse radial forearm flaps, two Quaba flaps, six cross finger flaps, one reverse homodigital island flap, three first dorsal metacarpal artery flaps, two thenar flaps, and two Moberg flaps were performed. Patients were followed up for an average of 11.9 ± 8.1 weeks. During this time, no postoperative complications occurred. All patients demonstrated appropriate healing at donor and recipient sites. Full range of motion was regained for all patients. Conclusions: WALANT is safe and effective for use in local and regional soft tissue flap surgery. Surgeons should consider this technique for more involved procedures such as flap surgery, as preliminary results demonstrate positive outcomes and potentially superior recovery for patients.
