Predictors of early dialysis vascular-access failure after thrombolysis

Abstract

Background: Vascular-access patency is critical for effective and uninterrupted haemodialysis. Limited literature exists evaluating if a surgical or repeated radiological approach is superior for reocclusion following failure of radiological recanalization. Few consistent early predictors of failure have been identified after radiological intervention for thrombosed vascular access. Methods: 138 patients with thrombosed arteriovenous fistulas or prosthetic grafts treated by radiological intervention, over 10 years, were retrospectively investigated. Reocclusion was treated by either repeated thrombolysis or surgery. Radiological patency rates, after first and second episodes of access thromb..
