Abstract

Abstract : Background: In distal lower limb defects, the paucity of local tissues dictates a free-flap (FF)-based reconstruction frequently. The propeller perforator flap (PPF) offers a good alternative when the patient or the limb or both are not fit for FF-based reconstruction. Also, in contexts of restricted healthcare resources, armed conflict scenarios, or during pandemics like the ongoing COVID-19 pandemic, PPF is considered a valuable alternative to free-flap-based reconstruction. Additionally, PPFs are less sacrificing in terms of major limb vessels and distal limb vascularity. Yet, the distal lower limb vascular impact for PPF-based reconstruction has not been studied before. Methods: In total, 23 patients with distal lower limb defects were reconstructed with PPFs. By using U/S arterial duplex, the peak arterial velocity (PA velocity) was measured pre and postoperatively in 15 (65.2%) out of the 23 patients. This measurement was done to the vessel segment distal to the used perforator. Results: An estimated 21 out of 23 flaps succeeded to reconstruct the patients' defects safely and to give all patients stable coverage without further surgeries. Only two patients had flap failure, which was managed successfully through additional reconstruction sessions. The difference between pre- and postoperative PA velocity was not statistically significant. Conclusions: PPFs are a safe cost-effective reconstruction modality for distal lower limb defects. This advantage is very valuable in cases of restricted healthcare resources, wars, and during pandemics. In terms of distal limb vascularity, PPFs have no significant impact and can be used safely.
