LATE RESULTS OF TREATING PATIENTS WITH OCCLUSIVE-STENOTIC LESIONS OF THE AORTA INFRARENAL SEGMENT'S MAIN ARTERIES

The aim: To analyze the results of surgical treatment in the late postoperative period after using modern types of surgical technologies for occlusive-stenotic atherosclerotic lesions of the infrarenal aorta's main arteries.

Materials and methods: The total of 420 patients were operated on. The patient's age ranged from 45 to 87 years (in the mean, 66.7±2.3 years). Men pre¬dominated - 375 (89.29%), and women were 45 (10.71%). According to the ischemia classification by Rutherford - 324 (77%) patients fell under categories 4, 5, 6 of the classification. 98 patients were operated on by the open method, 243 by the endovascular method, and 79 by the hybrid method. We assessed such indices as: postoperative thrombosis, limb amputations, mortality, and repeated operations performed due to complications or unsuccessful results of the primary operation.

Results: It was ascertained, a decrease in the number of postoperative complications from 7.87% to 4.39% (t=2,11, p=0,035), repeated operations - from 7.87% to 4.39% (t=2,11, p=0,035), amputations - from 3.63% to 2.19% (t=1,24, p=0,214) and mortality - from 3.03% to 1.09% (t=2,03, p=0,042) in the group where in-depth examination methods were applied, a treatment algorithm based on individual anatomical and hemodynamic features was implemented, techniques for performing operations were improved.

Conclusions: The analysis of late results of surgical interventions showed that the largest number of complications was found in the group of patients with multistory occlusive-stenotic lesions of arteries.
