How does endovascular treatment affect the risk of poststroke epilepsy?

The risks of poststroke epilepsy (PSE) after reperfusion treatment remains unrecognized. This study evaluated the risk of PSE after endovascular treatment (EVT) in 3,319 individuals and 2 control groups (n=3,132 on intravenous thrombolysis [IVT]; n=3,184 not on treatment).
Survival after an adjusted 2-year risk assessment was 6.5% after EVT, 10.0% after IVT, and 12.3% after no revascularization. Patients had a lower risk of PSE after EVT compared with the no treatment group. Additionally, factors that predict PSE after EVT attributed to large infarction, high treatment NIH Stroke Scale and support 3 months after stroke.
According to the authors, EVT lowers the risk of PSE and IVT before EVT conferred protection against PSE.
