Evaluation of mechanical thrombectomy in acute ischemic stroke related to a distal arterial occlusion: A randomized controlled trial.
Research article published in International journal of stroke : official journal of the International Stroke Society (2023)
Abstract
RATIONALE: Mechanical thrombectomy (MT) associated with the best medical treatment (BMT) has recently shown efficacy for the management of acute ischemic stroke (AIS) secondary to a large vessel occlusion. However, evidence is lacking regarding the benefit of MT for more distal occlusions. AIM: To evaluate the efficacy in terms of good clinical outcome at 3 months of MT associated with the BMT over the BMT alone in AIS related to a distal occlusion. METHODS: The DISCOUNT trial is a multicenter open-label randomized controlled trial involving French University hospitals. Adult patients (⩾18 years) with an AIS involving the anterior or posterior circulation secondary to a distal vessel occlusion within 6 h of symptom onset or within 24 h if no hyperintense signal on fluid attenuation inversion recovery acquisition will be randomized 1:1 to receive either MT associated with the BMT (experimental group) or BMT alone (control group). The number of patients to be included is 488. STUDY OUTCOMES: The primary outcome is the rate of good clinical outcome at 3 months defined as a modified Rankin scale (mRS) ⩽2 and evaluated by an independent assessor blinded to the intervention arm. Secondary outcomes include recanalization of the occluded vessel within 48 h, angiographic reperfusion in the experimental group, 3-month excellent clinical outcome (mRS ⩽ 1), all adverse events, and death. A cost utility analysis will estimate the incremental cost per quality-adjusted life year (QALY) gained. DISCUSSION: If positive, this study will open new insights in the management of AISs. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05030142 registered on 1 September 2021.

Por qué esto importa para la hirudoterapia
Este es el artículo de fundamentación y diseño del ensayo DISCOUNT, un ensayo controlado aleatorizado, multicéntrico y abierto en hospitales franceses que planea incluir a 488 pacientes para evaluar si la trombectomía mecánica más el mejor tratamiento médico supera al mejor tratamiento médico por sí solo en el accidente cerebrovascular isquémico agudo causado por una oclusión de vaso distal (en lugar de grande), con un buen resultado clínico (escala de Rankin modificada <=2 a los 3 meses) como criterio de valoración principal. Para la ASH es periférico, lo que ilustra que incluso para las emergencias trombo-oclusivas establecidas, la base de evidencia se construye criterio por criterio a través de RCTs rigurosos, el mismo estándar contra el cual debe medirse cualquier afirmación sobre la hirudoterapia. Advertencia: este resumen describe únicamente un protocolo, sin reportar resultados ni datos de eficacia; el ensayo fue registrado (NCT05030142) pero los resultados estaban pendientes, y el estudio se refiere a la trombectomía basada en dispositivos, no a la terapia con sanguijuelas ni al secretoma.
