The median Alberta Stroke Program Early CT score was 10 and good collaterals were observed in 10 of 17 occluded middle cerebral artery areas. No study patients had received intravenous thrombolysis therapy. EVT was performed on 18 of the 20 occluded arteries and mechanical thrombectomy on 13 vessels. The successful reperfusion (modified Thrombolysis in Cerebral Infarction grade \u22652\u2009b) rate was 67% in all EVTs and 85% with mechanical thrombectomy. Histological analysis showed fibrin-rich thrombi in four of five samples. Seven of 12 patients (58%) maintained their neurological function (modified Rankin Scale score \u22642\u2009or equal to pre-stroke score) at 90 days. Periprocedural complications comprised two symptomatic intracranial hemorrhages and the 90-day mortality rate was 13%.
