[Preventive surgery after vascular reconstruction for chronic lower limb ischemia]

To analyze the results of redo reconstructions of lower limb arteries in patients with obliterating atherosclerosis, immediate and long-term results in patients who underwent reconstructive interventions with occlusion of previous reconstruction and preventive interventions.

The study included 43 patients. The main group (group 1) consisted of 18 patients who underwent preventive vascular reconstructions. The control group enrolled 25 patients who underwent redo interventions for occlusion of previous reconstructions. The control group was divided into 2 parts; 15 patients had chronic limb ischemia (group 2), 10 patients had acute limb ischemia (group 3). Mean age of patients was 56.8±8.2 years; there were 37 (86%) men and 6 (14%) women. Multifocal vascular atherosclerosis was noted in 41 (95.3%) patients, carotid artery lesion - 29 (70.7%), coronary artery disease - 34 (79%). Patients with type II diabetes mellitus were excluded.

We chose each surgical intervention considering preoperative diagnostic data. Open, endovascular and hybrid interventions were performed. There were no deaths and limb amputations in the 1^st group. Two (13.3%) amputations were registered in the 2^nd group, 3 (30%) amputations and 1 (10%) death were registered in the 3^rd group. The follow-up period was 24 months. An 18-month freedom from amputations was 71.5%, 78% and 38%, respectively (p<0.05 compared to the 1^st and 2^nd groups).

Preventive surgical interventions prevent ischemia and amputation, as well as improves the results of redo surgery.
