PERCUTANEOUS TRANSLUMINAL ROTARY ATHERECTOMY IN PATIENTS WITH ATHEROSCLEROTIC LESIONS OF BELOW THE KNEE ARTERIES.

Abstract

The aim: To determine the effectiveness of the combination of the percutaneous transluminal rotational atherectomy (PTRA) techniques with plain old balloon angioplasty (POBA) and POBA monotherapy (POBA-mono) in endovascular treatment (ET) of patients with occlusive-stenotic lesions below the knee (BTK) arteries. Materials and methods: We studied two groups, the main included patients (n=9) aged who underwent PTRA and POBA of BTK arteries, and the comparative group (POBA-mono) of patients (n=24) who underwent POBA monotherapy of BTK arteries. Results: Thrombosis of the reconstructed segments in the target arteries after 12 months was diagnosed in 95% of patients of the control and 1 - main groups (Ft, p=0.00001). Healing of trophic ulcers of the foot in the first month after ET was observed in 78% (n=7) of patients of the main group and in 13% (n=3) of the control group (χ2 (1, n=33) = 10.2961; p=0.0013), and after 3 months - in 100% (n=9) and 83% (n=20) of patients in the respective groups. Conclusions: The combination of PTRA with POBA reduces the probability of repeated violations of the patency of the target artery. In addition, it increases the healing efficiency of trophic ulcers of the LE compared to POBA monotherapy.
