Evaluation of Complications and Success Rate and openness Rate of arterioarterial Grafts in Dialysis Patients without Dialysis Vascular access Running Head: Success Rate and openness Rate of arterioarterial Grafts

Abstract

Chronic renal failure has been considered as one of the main health problems in Asian countries. The term ESRD is a stage of CKD that causes uremic syndrome with the accumulation of toxins, fluids, and electrolytes. In the present study, the complications and success rate and openness of arterial graftswere investigated in dialysis patients without dialysis vascular access.The present study is a cross-sectional and descriptive study. The statistical population of the study population was patients who did not have suitable large deep veins in 2019 and 2020 and were candidates for arterioarterialgraft.The sample pf present study included patients who had multiple accesses to the upper and lower limbs and dysfunction in these limbs. Ten samples were investigated in this study. Inclusion criteria of the study included the patients for whom upper and lower limb venography was performed. In the case of inferior and superior vena cava obstruction and failure to establish flow with endovascular intervention, they became candidates for arterioarterialgraft and entered the study. Data were summarized in SPSS22software using tables and charts.In this study, 6 patients were male and 4 were female. The mean age of the patients was 57.45±8.6 years. The largest number of patients (50%) had diabetes mellitus. One case of stenosis in anastomosis and one case of thrombosis were observed in the patients. The initial success rate in patients within 12 months was 80%.Arterioarterialgraft is a new technique and an alternative to specific conditions when other options fail. This technique can be considered for patients with central venous obstruction.
