Vascular access for hemodialysis and hemodynamics
Válek, Martin ; Lopot, František (advisor) ; Malík, Jan (referee) ; Roček, Miloslav (referee)
The study is based on the program of monitoring of the state of surgically created vascular accesses by measuring the vascular access blood flow (QVA). Besides the comprehensive analysis of factors influencing the value of QVA it discussed in detail hemodynamic changes caused by the presence of non-physiological arteriovenous anastomosis. The study is based on data acquired in the course of more than 10 years during which this program has been routinely used and is based on data from 506 patients with a total of 4,296 measurements of QVA. In patients, QVA is significantly inter- and intraindividually variable. QVA is significantly influenced by multiple factors and corresponds also to the overall health of the patient. No simple factor has been proven to predominantly influence QVA. The study points out the significant long-term physiological variability of QVA (23%) as a parameter that was not taken into account despite its importance in deciding on the correct indication of radiological interventions. The study also analyzes the strong correlation between QVA and cardiac output. It brings a new method of evaluation of the influence of vascular access on myocardium through a calculation of the load of left ventricle and shows that there is a strong non-linear dependency between the flow and the...
