Acute Recanalization of Large Vessel Occlusion in the Anterior Circulation Stroke: Is Mechanical Thrombectomy Alone Better in Patients over 80 Years of Age? Findings from a Retrospective Observational Study
Abstrakt
Real-world data report worse 3-month clinical outcomes in elderly patients with acute ischemic stroke (AIS) treated with mechanical thrombectomy (MT). The aim was to identify factors influencing clinical outcome in elderly patients with anterior circulation AIS treated with MT (+-intravenous thrombolysis (IVT)).
In a retrospective, monocentric study, analysis of prospectively collected data of 138 patients (>=80 years) was performed. IVT was an independent negative predictor (OR 0.356; 95% CI: 0.134-0.942) and female sex an independent positive predictor (OR 4.179, 95% CI: 1.300-13.438) of 3-month good clinical outcome (modified Rankin scale 0-2).
Female sex was also an independent negative predictor of 3-month mortality (OR 0.244, 95% CI: 0.100-0.599). Other independent negative predictors of 3-month good clinical outcome were older age, lower pre-stroke self-sufficiency, more severe neurological deficit and longer procedural intervals.
Mortality was also independently predicted by longer procedural interval and by the occurrence of symptomatic intracerebral hemorrhage (p =80 years with anterior circulation AIS undergoing MT (+-IVT), IVT reduced the chance of 3-month good clinical outcome and female sex was associated with a greater likelihood of 3-month good clinical outcome and lower probability of 3-month mortality.
