Introduction: Arteriovenous (AV) fistula creation is the most common surgical procedure for providing vascular access for haemodialysis in patients with chronic kidney disease (CKD). The functioning of fistula dictates the quality of dialysis and the longevity of patients. The most common circumstances that require surgical takedown of AV fistula are thrombosis and rupture. While some patients undergo elective AV fistula takedown post renal transplantation or for cosmesis, majority of patients presenting with life-threatening rupture require emergency surgery for AV fistula takedown with or without maintaining arterial continuity. This study aims to compile our experience with surgical management of various AF fistula complications.Methods: This is a retrospective study of 29 patients who underwent Arteriovenous Fistula takedown in our institute over a period of 3years from May 2021 to May 2024.
Results: The most common cause of fistula takedown in our setup was rupture (n=25, 86.21%). AV fistula takedown was done in all cases (n=29, 100%). Arterial ligation was done in all infected cases (n=22, 75.86%) whereas in non-infected cases arterial continuity was maintained by repair or interposition venous graft. There was no aneurysm or psedoaneurysm formation or limb ischaemia in a follow up period ranging from 1month to 3 years.
Conclusion: Erroneous ways of cannulation and lack of awareness of fistula care were the prime cause of AV fistula complications. Early detection and presentation to healthcare setup could offer a better prognosis for limb salvage in the long term and decrease the incidence of morbidity and mortality.
