Endovascular treatment for M2 occlusions in the era of stentrievers: a descriptive multicenter experience

Background Patients with M2 middle cerebral artery (MCA) occlusions are not always considered for endovascular treatment. Objective To study outcomes in patients with M2 occlusion treated with endovascular procedures in the era of stentrievers. Methods We studied patients prospectively included in the SONIIA registry (years 2011–2012)—a mandatory, externally audited registry that monitors the quality of reperfusion therapies in Catalonia in routine practice. Good recanalization was defined as postprocedure Thrombolysis in Cerebral Infarction (TICI) score 2b–3; dramatic recovery as drop in National Institutes of Health Stroke Scale (NIHSS) score >10 points or NIHSS score
