Acute occlusions of arteries such as those of the cerebral and peripheral circulation are usually due to thrombotic or embolic events. Emboli have not been previously reported to cause arteriovenous (AV) dialysis access malfunction. We describe in this report three patients with end-stage renal disease (ESRD) and atrial fibrillation (Afib) who developed acute ischemia of an arteriovenous access-bearing extremity due to embolization. The clinical manifestations mimicked thrombotic events, but the presence of symptoms and signs of limb ischemia distinguished these cases clinically. A timely diagnosis followed by an appropriate intervention can lead to limb and access salvage.
