- Microcatheter to Recanalization (Procedure Time) Predicts Outcomes in Endovascular Treatment in Patients with Acute Ischemic Stroke: When Do We Stop?
This study addresses the relationship among procedure time, recanalization, and clinical outcomes in patients with acute ischemic stroke undergoing endovascular treatment. Demographics, NIHSS scores before and 1 day after the procedure, and modified Rankin Scale scores were assessed in 209 patients. Patients with procedure times ≤30 minutes had lower rates of unfavorable outcome at discharge compared with patients with procedure times ≥30 minutes. Rates of favorable outcomes in endovascularly treated patients after 60 minutes were lower than rates observed with placebo treatment. Unfavorable outcome was positively associated with age, admission NIHSS strata, and longer procedure times.
- Factors Influencing Clinically Meaningful Recanalization after IV-rtPA in Acute Ischemic Stroke
Predictors of clinically meaningful recanalization were assessed in 126 patients with acute anterior circulation stroke treated with IV thrombolysis. End points were CT angiographic recanalization and good clinical outcome at 90 days. Clinically meaningful recanalization occurred in 29% of patients, who had fewer neurologic deficits and higher ASPECTS at baseline. Admission NIHSS score and site of arterial occlusion were significant predictors of meaningful recanalization. Specifically, mild baseline deficits and distal vessel occlusions were significant predictors of clinically meaningful recanalization. A combination of these was better than either parameter alone.
