Symptomatic intracranial stenoses display an increased risk for ischemic stroke. Until now, only retrospective studies have demonstrated a positive effect of oral anticoagulation for prevention of further ischemic strokes. However, this therapy is widely used. The aim of the present study was to examine the efficacy and safety of oral anticoagulation for patients with symptomatic intracranial stenoses in clinical practice. Sixty-one patients with the diagnosis of symptomatic intracranial stenosis between 1992 and 1998 and who received oral anticoagulation were interviewed and examined in 2000. Ten patients suffered ischemic strokes (eight TIA, two completed strokes), and a subdural hematoma occurred in one patient. Six patients died during the observation period. In none of these cases was the death related to oral anticoagulation. Eight extracerebral bleedings occurred. An annual rate of 3% per year for ischemic strokes could be calculated. The annual rates for intracerebral and extracerebral bleeding amounted to less than 1% per year and 2.6% per year, respectively. Thus, oral anticoagulation in patients with symptomatic intracranial stenoses seems to be safe. Although the results suggest its efficacy, this cannot be proven due to the small number of patients examined and due to the design of the study.
