[Acute ischemic stroke in anterior territory: endovascular treatment]

Endovascular treatment (EVT) has become the standard of care for acute ischemic stroke (AIS) with proximal large vessel occlusions (LVO). However, it is still unknown whether these results can be generalized to clinical practice. We aimed to perform a retrospective review of patients who received EVT up to 24 hours, and to assess safety and efficacy in everyday clinical practice. We performed a retrospective analysis, from January 2013 to December 2017, on 139 consecutive patients with AIS for anterior circulation LVO strokes up to 24 h from symptoms onset, who received EVT in our institution. The primary outcome measured was a modified Rankin scale (mRS) = 2 at 90 days. Secondary outcomes included successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, mortality rate at 90 days and symptomatic intracranial hemorrhage (sICH). The mean age was 67.5 ± 15.0, with 51.8% female patients. Median baseline National Institute of Health Stroke Scale (NIHSS) was 14 (IQR 8-18); median time from symptom onset to groin puncture was 331 min (IQR 212-503). Sixty-three patients (45.3%) were treated beyond 6 hours after symptoms onset. The rate of mRS = 2 was 47.5%. Successful reperfusion was achieved in 74.8 %. Mortality rate at 90 days was 18.7 % and sICH was 7.9 %. Our registry of real-life patients with AIS due to LVO who received EVT within 24 hours showed high reperfusion rates, and good functional results with few complications, according to international recommendations.
