dc.description.abstractBackground: Arterial revascularization and free flap reconstruction is safe and effective for limb salvage in patients with critical limb-threatening ischemia (CLTI). This study aimed to determine whether reconstruction outcomes were affected by the time interval between endovascular treatment and free flap transfer in lower extremity reconstruction for critical limb ischemia. Methods: Patients who underwent endovascular intervention and subsequent free flap reconstruction with >6 months of follow-up were reviewed. Those with wounds with oncological and traumatic etiologies were excluded. Patients’ demographics, risk factors, details of microsurgical procedures, details of endovascular intervention, and flap outcomes were collected. Results: Overall, 64 consecutive patients (M:F = 50:14 and mean age, 57.3 [range, 29–82] years) were evaluated between November 2011 and October 2019. Angioplasty failed in three patients. For soft-tissue reconstruction, anterolateral free flaps were used most frequently (n = 54 and 84.4%). Flap-related complications developed in 12 cases, of which five cases included total flap necrosis. The interval between endovascular intervention and free flap transfer was not associated with flap loss in multivariate regression analysis. Patients with kidney transplants and higher serum creatinine were associated with total flap necrosis. Advanced age, failed angioplasty, and perfusion status of the pedal arch were associated with major flap complications. Conclusion: The time interval between endovascular treatment and free flap reconstruction was not associated with flap complications. Free flap reconstruction of chronic wounds caused by CLTI can be safely planned regardless of the time duration from preoperative angioplasty.-
