Headache After Coil Embolization for Unruptured Intracranial Aneurysms
Headache After Coil Embolization for Unruptured Intracranial Aneurysms
Perform a prospective cohort study to compare the incidence and severity of headache between
 non-stent assisted coiling and stent assisted coiling of unruptured intracranial aneurysms.
severity of headache - assess with visual analogue scale characteristics of headache after
 stent deployment or simple coiling Duration of headache after intervention
