Abstract
Mechanical thrombectomy is an effective recanalization technique in acute ischemic stroke patients with large vessel occlusions; however, it is unclear to what extent stent retriever thrombectomy may be applicable to occlusions of smaller peripheral cerebral vessels. The outcome of patients with isolated M2 occlusions treated with the Mindframe Capture low profile (LP) stent retriever was reviewed. Aretrospective review of prospectively collected data on all consecutive patients treated for isolated M2 occlusions between June 2013 and December 2017 using the Mindframe Capture LP was performed. Technical aspects of the recanalization procedure, recanalization rate, complication rate, and clinical outcome were analyzed. Mechanical thrombectomy with the Mindframe Capture LP was performed in 38patients (median age 79years) with an isolated M2 occlusion. The median National Institutes of Health Stroke Scale (NIHSS) score on admission was 7.5 (interquartile range, IQR 5-12) and successful reperfusion modified Thrombolysis in Cerebral Infarction (mTICI2b or 3) was achieved in 28patients (74%). Acompensated/adjusted modified Rankin Scale (mRS) 0-2 at 3months was observed in 65% when taking pre-stroke disability into account. Symptomatic intracranial hemorrhage (sICH) occurred in 1patient (2.6%). Asymptomatic intracranial hemorrhage (aICH) was noted in 8patients (21%) and asmall subarachnoid hemorrhage (SAH) in the immediate vicinity of the target vessel was apparent in 8patients (21%). The Mindframe Capture LP is atechnically effective thrombectomy device for the treatment of isolated M2 occlusions. The lower profile of the device is advantageous when targeting peripheral intracranial occlusions.
