Manejo avanzado del infarto cerebral en un hospital público chileno: trombectomía mecánica en el Hospital Barros Luco Trudeau / Mechanical thrombectomy in a Chilean public hospital. Experience in 149 patients

BACKGROUND: Mechanical thrombectomy is the accepted treatment for acute ischemic stroke in Large Vessel Occlusion. The Barros Luco Trudeau hospital developed endovenous thrombolysis in 2010, and since 2012, implemented endovascular management, becoming the neurovascular center in the southern area of the metropolitan region. AIM: To describe endovascular management of acute ischemic stroke in a Chilean public hospital. Material and Methods: Analysis of patients with acute ischemic stroke that were treated with mechanical throm-bectomy from 2012 to 2019 in the Barros Luco Hospital. RESULTS: In the study period, a mechanical thrombectomy was carried out in 149 patients aged 61 ± 15 years (46% females). The average National institute of Health Stroke Scale (NIHSS) at presentation was 19 ± 4-5. Anterior or posterior circulation involvement was present in 89.9 and 10.1 % of patients. Twenty-five percent of patients were referred from other public centers. The mean lapse between onset of symptoms and thrombectomy was 266 ± 178 in. Ninety days after the procedure, 58% of patients had minimal or absent disability (Modified Ranson score of 0-2), and 19,2% died. CONCLUSIONS: Mechanical thrombectomy, according to this experience, has favorable clinical outcomes in patients with high NIHSS scores at entry.

Complicaciones neurológicas tras intervencionismo cardíaco percutáneo / Neurological complications following percutaneous coronary intervention

Resumen Introducción: Las complicaciones neurológicas agudas del intervencionismo cardiaco percutáneo (ICP) son variadas e infrecuentes, pero pueden resultar fatales. Casos: Presentamos un ictus isquémico -II- (caso 1), y dos casos de encefalopatía por contraste -EC- (2 y 3). Dos varones (1 y 2) y una mujer (3), con FRCV y edad media de 76 años. Los tres pacientes debutaron con focalidad neurológica aguda (FNA) al finalizar el procedimiento, lo que motivó la activación de código ictus intrahospitalario desde cardiología. 2 y 3 asociaron además agitación. El TC multimodalfue normal en 2y 3, y mostró oclusión de M1 izquierda en 1. Se desestimó tratamiento de reperfusión cerebral en 1 por anticoagulación. El EEG fue normal en 2 y mostró paroxismos focales en hemisferio izquierdo de baja persistencia en 3.2 y 3 fueron tratados con sueroterapia y anticomiciales (3), quedando asintomáticos en las primeras doce horas. 1 falleció a los diez días por infección respiratoria. Conclusiones: En presencia de FNA tras ICP, la sospecha clínica resulta vital para establecer un diagnóstico diferencial precoz entre II y EC, y considerar tratamiento específico urgente, ya que puede modificar el pronóstico del paciente.

Introduction: Percutaneous coronary intervention (PCI) related neurological complications are wide and rare, but may be fatal. Cases: We present an ischaemic stroke -IS- (case 1), and two cases of contrast induced encephalopathy -CIE- (2 and 3). Two males (1 and 2) and one woman (3), with vascular risk factors and an average age of 76. All of them presented with acute focal neurological symptoms at the end of the procedure and Stroke Code was activated inmediately. 2 and 3 also associated psychomotor agitation. Multimodal CT head was normal in 2 and 3, whereas it showed a left Ml occlusion in 1. Reperfusion treatment was contraindicated 1 due to anticoagulation. EEG was normal in 2 and showed focal paroxisms in left hemisphere in 3.2 and 3 were successfully treated with fluids and antiepileptics (3). 1 died due to respiratory infection. Conclusions: Acute focal neurological symptoms following PCI should make us consider IS and CIE and provide the patient with urgent specific treatment.
