The purpose of this study was the evaluation of procedural and outcome data of patients 90 years of age or older undergoing endovascular stroke treatment. The authors retrospectively analyzed prospectively collected data of 29 patients (mean age 91.9 years) in whom endovascular stroke treatment was performed between January 2011 and January 2016 (from a cohort of 615 patients). Successful recanalization (TICI % 2b) was achieved in 22 patients (75.9%). In 9 patients, an NIHSS improvement ≥ 10 points was noted between admission and discharge. After 3 months, 17.2% of the patients had an mRS of 0-2. Despite high mortality rates (∼45%) and moderate overall outcome, 17.2% of the patients achieved mRS 0-2 or prestroke mRS, and no serious procedure-related complications occurred.
