To prevent the development of postoperative thrombosis of the reconstruction segment after endovascular and hybrid revascularization of the femoral-distal arterial portion in the conditions of stenotic-occlusive process of the tibial arteries by forming functionally capable pathways in the tibial segment.                Materials and methods. The results of treatment 135 patients with atherosclerotic occlusive-stenotic lesions of the infrainguinal arterial segment of the lower extremities were analyzed. According to the severity violation of chronic arterial insufficiency of the lower extremities, grade IIB was detected in 50 (37.04%) patients, grade III - in 63 (46.66%) examinee, grade IV- in 22 (16.30%) examinee. Patients were divided into 2 groups. Group I included 61 (45.19%) patients with occlusal-stenotic lesions at the level of the infrainguinal segment, who underwent only endovascular correction of the peripheral arterial portion, the second group consisted of 74 (54.81%) patients with multilevel occlusive-stenotic lesions of the infrainguinal arterial segment which was performed hybrid arterial reconstruction.                Results and discussion. The proposed tactic involves endovascular angioplasty of at least two tibial arteries. During revascularization of 135 patients by endovascular (61 supervision) and hybrid (74 supervision) methods of a femoral-distal arterial blood flow under conditions of arterial sclerotic disease of tibial arteries carried out in 115 (85,18%) patients endovascular dilatation of two arteries.Thrombosis of the reconstruction segment in the postoperative period was finding in 9 (6.67%) cases: when using endovascular and hybrid revascularization methods, respectively - in 4 (6.56%) and 5 (6.76%) cases. Thrombosis of the reconstruction segment in the early postoperative period in 8 cases developed after endovascular angioplasty of one of the tibial arteries and only in 1 observation after endovascular angioplasty of 2 tibial arteries.                Conclusion. Reconstruction of outflow pathways at the tibial arterial segment with occlusive-stenotic lesions of the infranguinal arterial portion during endovascular and hybrid techniques of revascularization by performing angioplasty of the two tibial arteries of the tibia can provide a positive result of revascularization in the early postoperative period, respectively in 95.08% and 95.95% of cases.
