“…The mortality rate of patients with diabetes following amputation is high, between 39% and 80% at 5 years (Chou et al, 2016;Hong & Oh, 2012;Oh et al, 2013;Moran, Illig, Green, & Serletti, 2002;Moulik, Mtonga, & Gill, 2003) and amputation of the contralateral limb occurs within 2 years of the first amputation in approximately 50% of patients (Ecker & Jacobs, 1970;Kucan & Robson, 1986;Oh et al, 2013) The combination of revascularization with free tissue transfer for the treatment of diabetic lower leg and foot soft tissue defects leads to successful salvage of the diabetic limb (Briggs, Banis Jr., Kaebnick, Silverberg & Acland, 1985;Chou et al, 2016;Hong & Oh, 2012;Moran et al, 2002). Revascularization techniques, such as bypass surgery and percutaneous transluminal angioplasty (PTA), can increase the distal circulation, which is favorable for flap survival (Kim, Naidu, & Kim, 2010;Oh et al, 2013;Randon et al, 2010) Kim, Kim, Sung, Kim, & Kim, 2017;Kim et al, 2016;Youn, Kim, Kim, & Hwang, 2015). Perforator flaps with long vascular pedicles introduce more healthy and reliable vessels with minimal donor site morbidity and without including muscle tissue (Jeon et al, 2013;Kim et al, 2016Kim et al, , 2017.…”
