- Abstract:
- Background: Non-healing soft tissue defects pose challenges to treating physicians. Microsurgical reconstruction is a treatment option for achieving wound closure and limb salvage. These free tissue transfers are often challenging due to associated risk factors. This study aimed to evaluate microsurgical reconstruction using specialized microsurgical techniques for non-healing spontaneous or post-traumatic soft tissue defects in an elderly, high-risk patient cohort with peripheral artery disease. Methods: A retrospective study was conducted on patients with radiologically confirmed peripheral artery disease who underwent free tissue transfers between 2004 and 2010. Patients were included in whom one of two surgical techniques was used, including a "Y" configuration of the arterial pedicle, employed either as an interposition graft or as an arterial patch, or the use of a saphenous vein graft. Patient demographics, comorbidities, flap/limb survival, and surgical techniques were analyzed. Results: Twenty patients at a mean age of 68 (+/-9.3) years underwent 21 primary flap surgeries. Trauma-derived soft tissue defects were predominant (55%). Latissimus dorsi muscle flaps were most frequently utilized (52.4%). The flap success rate was 90.5% at a 12-month follow-up, with no secondary amputations recorded. The lost flaps were replaced by additional free tissue transfers without further complications. Conclusions: This study demonstrates the feasibility of free tissue transfers in high-risk patients with complex soft tissue defects and vascular calcifications. Thorough preoperative planning and the application of specialized surgical techniques are crucial for favorable outcomes in challenging clinical scenarios.
