Cognitive Outcome and Clinically Silent Thromboembolic Events After Coiling of Asymptomatic Unruptured Intracranial Aneurysms

Exhaustive neuropsychological evaluation of UIA patients who underwent coil embolization demonstrated recovery or improvements from baseline cognitive function after 4 weeks, although some patients still showed cognitive deficits at 4 weeks after the procedure. However, we found no statistically significant relationship between the presence and number of CSILs on DWI and cognitive changes after the procedure.
