THE I NFLUENCE OF INTRАDIАLYTIC HYPOTENSION ON THE FUNCTIONING OF АRTERIOVENOUSFISTULА

. Nowadays hemodialysis is the most widespread way of treatment concerning the end-stage renal disease. The variant of choice as for permanent vascular access for hemodialysis is arteriovenous fistula. An actual problem is the deterioration of the patency of arteriovenous fistula. According to the research, most patients do not know about the risks associated with intradialytic hypotension. Under these conditions, research with determining the level of critical intradialytic hypotension is particularly relevant. Purpose of the work is to study and evaluate intradialytic hypotension as a risk factor for thrombosis of arteriovenous fistulas. Materials and methods. 60 patients were examined with end-stage renal disease, receiving of hemodialysis. Among these patients a thrombosis of arteriovenous fistula appeared in the long term (7.5 (3.0–17.6) months) after the surgery. The average age of patients was (54.1 ± 11.8) years; there were 30 (50%) men, 30 (50%) women. Results. According to the results of our study, 38 (63 %) patients had hypotension at the end of the hemodialysis session. Conclusions. Blood hypotension is one of the main predictors of thrombosis of arteriovenous fistula in the late postoperative period. A decrease in systolic blood pressure on 35.0 (25.0–50.0) mm Hg to 100.0 (90.0–110.0) mm Hg is critical for the patency of arteriovenous fistula. Adequate control and correction of blood pressure (in particular, during a hemodialysis session) can prevent thrombosis of arteriovenous fistula.
