BackgroundAnticoagulated patients (APs) are excluded from the acute stroke management with alteplase in Europe, not in the United States. They could benefit from mechanical thrombectomy (MT), which was not undoubtedly proven. There are scarce data about its results in such patients. The authors' aim is to analyze the efficacy and safety of MT in APs presenting with an acute stroke in our institution.MethodsProspective observational study comparing 30 APs and 109 non-anticoagulated patients (N-APs) underwent direct MT without alteplase. Demographic data, clinical severity (National Institutes of Health Stroke Scale [NIHSS]), efficacy (recanalization thrombolysis in cerebral infarction [TICI] ≥ 2b and modified Rankin Scale score ≤ 2 at 3 months), and security (symptomatic intracranial hemorrhage [SICH], mortality at 3 months) were compared between both groups.ResultsIn both groups men were more frequent (63.3% of APs were men and 61.5% of N-APs were men). Mean age was 73 in APs and 67.2 in N-APs. Median NIHSS was similar (17 APs; 16 N-APs), also TICI greater than or equal to 2b (93.3% APs; 89.9% N-APs). The 3-month modified Rankin Scale score less than or equal to 2 was 46.7% in APs and 55.2% in N-APs (P = .40). SICH was present in 16.7% of APs and 8.3% of N-APs (P = .15). Mortality at 3 months was 6.7% in APs and 19% in N-APs (P = .08).ConclusionsMT is a valid treatment option in APs. It achieves an efficacy as in N-APs with a tendency to suffer more from SICH, but lower mortality. We hypothesize that cardioembolic clots may be easier to be removed than atherotrombotics, and that embolic stroke in APs might be less severe than that in N-APs or might suffer less of other complications than atherotrombotics.
