Reconstructive operations on pedal arteries in the treatment of critical limb ischemia

Abstract

The aim — to analyze results of reconstructive operations on pedal arteries in patients with critical limb ischemia (CLI).Materials and methods. From January 2008 to September 2017 in the Department of Vascular Surgery of Lviv Regional Clinical Hospital reconstructions of pedal arteries were performed in 41 patients with CLI. Middle age was 65 years (62, 97 %), male patients prevailed — 34 (83 %), female patients — 7 (17 %) respectively. During the period of supervision major amputations were performed in 5 (12.2 %) cases, in 28 (68.3 %) tissue loss was limited to the necrectomies and minor amputations.Results and discussion. Limb salvage was in 36 (87.8 %) patients. Using of popliteal artery as inflow provided better cumulative bypass patency comparatively with femoral artery bypass, the dependency of bypass and distal anastomosis localization was not statistically significant.Conclusions. Reconstructive operations on pedal arteries are an efficient method of CLI management in patients with distal occlusive stenotic damages and often remain as only chance to avoid amputation in patients with CLI. Better bypass flow is observed when popliteal artery is used as an inflow, the dependency on distal anastamosis localization was not defined.
