Comparison of the effectiveness of open revascularization operations with simultaneous damage to the arteries of the aorto-femoral and femoral-popliteal segments in patients with critical lower limb ischemia depending on the level of peripheral vascular resistance

Rationale: Multilevel atherosclerotic lesions of the lower extremity arteries are most commonly associated with the development of critical ischemia. Despite the prevalence of lesions of several arterial segments, there is no clear algorithm for performing revascularization operations. The choice of treatment tactics and the type of reconstructive surgery is still insufficiently reflected in the literature. Evaluation of the results of revascularization operations depending on the initial anatomy of the lesion of peripheral arteries and the state of the outflow channel in order to preoperative predict the effectiveness of revascularization became the basis for this study.
