ABSTRACT
BACKGROUND:
Endovascular treatment (ET) in orally anticoagulated (OAC) patients has not been evaluated in randomized clinical trials and data regarding this issue are sparse.METHODS:
We analyzed data from the German Stroke Registry-Endovascular Treatment (GSR-ET; NCT03356392, date of registration 22 Nov 2017). The primary outcomes were successful reperfusion defined as modified thrombolysis in cerebral infarction (mTICI 2b-3), good outcome at 3 months (modified Rankin scale [mRS] 0-2 or back to baseline), and intracranial hemorrhage (ICH) on follow-up imaging at 24 h analyzed by unadjusted univariate and adjusted binary logistic regression analysis. Additionally, we analyzed mortality at 3 months with adjusted binary logistic regression analysis.RESULTS:
Out of 6173 patients, there were 1306 (21.2%) OAC patients, 479 (7.8%) with vitamin K antagonists (VKA) and 827 (13.4%) with non-vitamin K antagonist oral anticoagulation (NOAC). The control group consisted of 4867 (78.8%) non-OAC patients. ET efficacy with the rates of mTICI 2b-3 was similar among the three groups (85.6%, 85.3% vs 84.3%, p = 0.93 and 1). On day 90, good outcome was less frequent in OAC patients (27.8%, 27.9% vs 39.5%, p < 0.005 and < 0.005). OAC status was not associated with ICH at 24 h (NOAC odd's ratio [OR] 0.89, 95% confidence interval [CI] 0.67-1.20; VKA OR 1.04, CI 0.75-1.46). Binary logistic regression analysis revealed no influence of OAC status on good outcome at 3 months (NOAC OR 1.25, CI 0.99-1.59; VKA OR 1.18, CI 0.89-1.56) and mortality at 3 months (NOAC OR 1.03, CI 0.81-1.30; VKA OR 1.04, CI 0.78-1.1.37).CONCLUSIONS:
ET can be performed safely and successfully in LVO stroke patients treated with OAC. CLINICAL TRIAL REGISTRATION-URL http//www.clinicaltrials.gov . Unique identifier NCT03356392.Palavras-chave
