- W2337415070 abstract ": Introduction: There are multiple factors in failure of arteriovenous fistula (AVF) in patients with chronic renal failure (CRF) who require periodic hemodialysis. Out of technical errors, hypertension, site of insertion, size of vessels, diabetes and atherosclerosis are the common causes of failure in AVFs. This study is designed to evaluate failure of AVF in patients. Methods: In this descriptive study, 100 fistulas from 75 cases of CRF patients who were referred for AVF during 1996-2000 were selected and operated upon AVF by a given surgeon with the same technique (end-to-side) and followed 2 years relatively. In addition to underlying disease such as diabetes mellitus, atherosclerosis and inappropriate vessels, other factors as hypotension and bleeding of aneurismal vessels were recorded when AVF failed. The results were reported using descriptive statistics. Results: 100 AVFs were inserted in 70 patients, 53 in snuff box of left hand, 26 in distal of left forearm, 17 cases in left arm and 4 ones in snuff box of right hand. 30% failed primarily (before dialysis) commonly due to drop in blood pressure and among next 70%, 47 patients had functional AVF for at least 20 months and 23 of them had 7.5 months function who then failed commonly due to hypotension during hemodialysis Conclusion: According to this study, hypotension was the cardinal cause of failure of AVFs in CRF patients. So we can reduce failure rate of AVFs by monitoring and controlling the blood pressure during hemodialysis and prevent hypotension by salted regimen intake." @default.
