Abstract
AIM OF STUDY: Mechanical thrombectomy (MT) is one of the aetiological treatment options recommended for anticoagulated patients with acute ischaemic stroke (AIS). We analysed its long-term outcomes using the modified Rankin Score (mRS) or mortality on day 90. CLINICAL RATIONALE FOR THE STUDY: Data describing the anticoagulant efficacy and safety of MT in patients with AIS is limited. MATERIALS AND METHODS: This study included 291 patients with AIS (49% women, mean [SD] age 66 [15] years) who underwent MT in the Comprehensive Stroke Centre in Krakow, Poland. Data describing demographics, stroke risk factors, NIHSS on admission, postprocedural thrombolysis in cerebral infarction score, 24-hour postprocedural haemorrhagic transformation (ECASS-2) as seen on computed tomography, and time between stroke onset and groin puncture was collected. The outcome measure was the mRS on day 90 after stroke onset (a favourable outcome was defined as an mRS not exceeding 2 points; an unfavourable outcome was death). RESULTS: Thirty-seven patients (13%) were on therapeutic anticoagulation during MT. Univariate analysis showed that anticoagulated patients were older and more likely to have been diagnosed with hypertension, ischaemic heart disease, or atrial fibrillation. The patient groups did not differ in terms of clot location, postprocedural thrombolysis in cerebral infarction score, haemorrhagic transformation on computed tomography, or mRS on day 90. Multivariate logistic regression analysis showed that younger age, male sex, no history of diabetes mellitus, lower NIHSS score on admission, shorter time between stroke onset and groin puncture, and better recanalisation were associated with favourable outcomes at day 90, and that therapeutic anticoagulation was not (OR, 1.00; 95%CI, 0.46-2.15; p = 0.99). Anticoagulation did not affect mortality at day 90 (OR, 1.28; 95%CI, 0.56-2.92; p = 0.55). CONCLUSION AND CLINICAL IMPLICATIONS: In anticoagulated patients with AIS, MT does not affect long-term outcomes.
