“…Also, immediate and long-term success of a newly constructed AVF depends on several hemodynamic factors, vessel characteristics, and surgeon experience [3][4][5][6][7][8][9][10][11][12][13][14][15][16] . MacAskill et al and Kim et al stated in their studies that preexisting or incoming intimal hyperplasia was an important factor in AVF survival.…”

“…Accordingly, AVF creation and long-term patency are of paramount importance for patients waiting for renal transplantation. The factors influencing the patency of AVF, such as diabetes mellitus (DM) [3] , previous heparin use [4] ,C-reactive protein [5] , preexisting intimal hyperplasia [6] , intraoperative blood flow measurements [7] , presence of malignancy, previous central venous catheter (CVC) insertion, preoperative arterial blood pressure (ABP), arterial inflow (AI), subclavian venous flow (SVF), operative venous outflow of the fistula [8] , hypertension, smoking [3,9,10] , reoperative radial arterial diameter [11] , surgeon experience [12] , have been explored.…”

Introduction: Creation and subsequent patency of arteriovenous fistula (AVF) is crucial for hemodialysis patients. Early thrombosis is one of the main reasons of fistula occlusion. This study aimed to explore the effect of blood pressure and the presence of visible arteriosclerosis in the artery used for anastomosis on the patency of AVF. Methods: This retrospective study AVF was created in 231 consecutive patients. We used the Brecio-Cimino technique to create AVF in 50% of patients. Perioperative systolic (SBP) and diastolic (DBP) blood pressures were recorded just before declampage and during the following 24-h period for each 6-h intervals. Age, gender, presence of macroscopic arteriosclerosis in the artery used for an astomosis, and the etiologic factors of chronic renal failure parameters were all equally recorded. Results: The overall early fistula survival rate was 83%. No statistically significant immediate fistula dysfunction in terms of blood pressure differences was found. The multivariate analysis of the factors related to the AV fistula in the first 24 h patency revealed that only upper arm fistula was more likely effective (OR=1.192, p=0.003). Discussion and Conclusion: The effect of age, gender, presence of arteriosclerosis, and the history of existence of central venous catheter on early AVF patency was not observed. The rate of fistula patency was higher in the upper arm compared to fistulas in the lower arm. No significant difference concerning AVF patency was observed between patients with arterial blood pressure higher or lower than 120 mmHg.

Introduction. 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.
