Abstract

Aim: Carotid artery stenosis and atrial fibrillation are diseases of the aging patient population. Literature lacks precise anticoagulation treatment protocols for patients with atrial fibrillation following carotid endarterectomy. We present our experiences with anticoagulation strategy in this particular patient population.Patients and methods: Between June 2001-September 2017, 165 patients with chronic or paroxysmal atrial fibrillation out of 1594 cases from three different institutions whom received Coumadin and aspirin and required carotid endarterectomy were reviewed, respectively. Mean age was 63.47.9 years. Male/female ratio was 102/63. There were 67 diabetic and 138 hypertensive cases.Results: Patients are followed a mean of 64.4 +/- 16.9 months. Early mortality occurred in two patients due to intracranial bleeding and heart failure. Another patient was lost due to intracerebral hemorrhage and 16 other patients died due to various causes in the late follow-up. Three patients required exploration against bleeding.Conclusion: Combination of warfarin with an aim to keep the INR value between 2 and 3, and aspirin at a dosage of 100mg per day seemed feasible and in our modest patient cohort. Further studies including multicenter larger data are warranted in order to establish a precise anticoagulation treatment protocol for patients with atrial fibrillation after carotid endarterectomy.
