The mean age and median baseline NIHSS were 65.4 years and 16, respectively. Successful reperfusion was achieved in 147 (91.9%) cases [at least modified Thrombolysis in Cerebral Infarction (mTICI) 2b] with aspiration alone, with complete reperfusion (mTICI 3) in 94 (58.8%) cases. Successful\/complete first pass reperfusion was achieved in 104 (64.60%) cases, including mTICI 2b in 34 (21.1%) cases and mTICI 3 in 70 (43.5%) cases. The time from groin puncture to successful reperfusion was 44 (33, 62) min. There were 16 (9.9%) cases requiring rescue therapy using stent-retriever. Procedure-related complications included 2 (1.3%) cases of arterial perforation, 2 (1.3%) cases of arterial dissection, 12 (7.5%) cases of distal embolization, and 1(0.6%) case of puncture site infection. The rate of symptomatic intracranial hemorrhage (sICH) was 3.8% and mortality rate was 13.8%. A total of 99 (62.3%) cases had a favorable outcome (mRS 0\u20132) at 90 days.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In current practice, the first-line aspiration approach with the Esperance<jats:sup>\u00ae<\/jats:sup> Distal Access Catheter is safe and efficacious.
