AV FISTULA EFFECTING BY ANTICOAGULANT AND ANTIPLATELET AGENTS
Journal Title: World Journal of Pharmaceutical and Medical Research - Year 2018, Vol 4, Issue 8
Abstract
Background: Arteriovenous fistula (AVF) is the primary mode of achieving vascular access for hemodialysis in chronic renal failure (CRF). Because of high complication rates like thrombosis, maintenance of the fistula is a major challenge. Although antiplatelets and anticoagulants are emerging rapidly for improving the outcome of AVF but fear of bleeding, hematoma, subsequent compression of AV fistula and blockade restrict their use in many dialysis centers. Methods: Seventy five patients for whom AVF was created for hemodialysis access from Feb 2013-April 2017 in Jinnah hospital, Lahore, Pakistan were included in a retrospective study. Analysis of results was done in two different age and sex matched groups; Group I had patients where no anticoagulants or antiplatelets were used and Group II had patients in which antiplatelets/anticoagulants were used. Results: There were 27 patients in group I and 48 patients in group II. Both the groups were followed up till 2 years post operatively to check for the patency of the fistula. AV fistula was repeated in 16 cases altogether. In group II there were 5 (10%) cases of repeat fistula while in group I it was repeated in 11 (40%) cases. Conclusion: Judicious use of antiplatelet/anticoagulant agents in cases of AVF for hemodialysis access can be beneficial in preventing the chances of occlusion of AVF and thus helps in its long term patency. in 1966, overcame many of the problems of external dialysis shunts but thrombosis and blockage of fistula still remains of achieving vascular access for hemodialysis in patients with chronic renal failure and was first introduced in 1960 by Quinton-Scribner.1 Because of high complication rates like thrombosis,[1-3] maintenance of vascular access for hemodialysis is a major challenge in care of hemodialysis patients. Autologous AVF introduced by Brescia and Cimino an annoying problem in day to day practice of each vascular surgeon.[4]
