Full Metall Jacket Multilevel Segment
Hypothesis: "Total" endovascular revascularization of a multistory lesion of the iliac-femoral-popliteal segment is safer and a better quality of life is achieved in comparison with hybrid intervention. The lack of damage to the skin avoids complications in the postoperative and remote periods of observation, thereby improving the quality of life
