Abstract

In patients with chronic critical lower limb ischemia, the deep femoral artery (DFA) condition plays an important role. The localization of atherosclerotic plaque in DFA and its spread are diverse. A purposeful study of isolated profundoplasty as an independent method of revascularization of an ischemic limb belongs to P. Martin et al. (1968). According to some authors, the most important factor for predicting a satisfactory long-term result is the presence of developed collaterals from the DFA branches to the tibial arteries. At the present time, various methods of profundoplasty are performed. The most common technique for DFA reconstructing is the endarterectomy and patch angioplasty. Autogenous (autovena or autoartery) and synthetic materials may be used as a patch. In this case, profundoplasty is classified depending on the arteriotomy length: short (<2 cm), standard (<8 cm or up to the first perforator), and extended (> 8 cm, or beyond the first perforator). Profundodoplasty is a time-proven effective method of surgical intervention in the treatment of lower limb ischemia. One of the potential advantages of isolated profundoplasty may be the reduction of the ischemia degree and decrease of amputation risk. However, the question of indications for conducting profundoplasty remains unresolved. The choice of the technique and the final volume of surgical intervention is crucial for the best result (limb salvage, regression of the chronic lower limb ischemia degree).
