Mechanical Thrombectomy in Patients with Acute Ischemic Stroke on Anticoagulation Therapy.
Research article published in Cardiovascular and interventional radiology (2018)
Abstract
INTRODUCTION/PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. MATERIALS AND METHODS: All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis. Neurological deficit was scored using National Institutes of Health Stroke Scale (NIHSS) and 90-day clinical outcome using modified Rankin scale with a score 0-2 for good outcome. Recanalization was rated using Thrombolysis in Cerebral Infarction (TICI) scale. Symptomatic intracerebral hemorrhage (SICH) was assessed according to the SITS-MOST criteria. RESULTS: Out of 703 patients treated with MT, 88 (12.5%) patients (46% males, mean age 75.5 ± 11.8 years) were on AT with an admission median NIHSS of 17 points. Recanalization (TICI 2b-3) was achieved in 80% and complete (TICI 3) in 65% of patients on AT and in 80 and 65% of patients without AT (p-1.000). SICH after MT was detected in 9% of AT and 5% of non-AT patients (p-0.136). Good outcome was present in 36% of AT patients (p-0.03). AT patients with poor outcome had more frequently atrial fibrillation (93%, p-0.005), higher admission NIHSS (17, p-0.004) and higher rate of SICH (14.5%, p-0.047). CONCLUSION: MT seems to be safe also in patients on AT. Poor outcome may be related to higher admission NIHSS, higher rate of SICH and presence of atrial fibrillation.

Resumen
Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis.
Por qué esto importa para la hirudoterapia
Este análisis retrospectivo unicéntrico comparó los resultados de la trombectomía mecánica en pacientes con accidente cerebrovascular isquémico agudo que estaban bajo terapia de anticoagulación frente a los que no lo estaban (88 de 703 pacientes bajo anticoagulación), reportando tasas de recanalización similares (TICI 2b-3 en el 80% de ambos grupos) y ningún exceso estadísticamente significativo de hemorragia intracerebral sintomática (9% vs 5%, p=0.136), mientras que los peores resultados funcionales en el grupo anticoagulado (buen resultado en el 36%) se asociaron con un NIHSS al ingreso más alto, mayor fibrilación auricular y mayores tasas de hemorragia. Para ASH, esto se enmarca en el panorama de evidencia clínica que rodea a la anticoagulación más que a la hirudoterapia en sí: documenta cómo el estado anticoagulante sistémico interactúa con la intervención del accidente cerebrovascular agudo y el riesgo de sangrado, el mismo eje de seguridad relevante para cualquier anticoagulante derivado de sanguijuelas en la historia del descubrimiento de fármacos del secretoma. Al tratarse de una cohorte retrospectiva, no aleatorizada y de un solo centro, las comparaciones son observacionales y la propia conclusión de los autores de que la trombectomía 'parece' segura bajo anticoagulación debe interpretarse como generadora de hipótesis; el estudio no involucra compuestos derivados de sanguijuelas.
