The frequency of neurologic complications of cerebral angiography is 0.3%-2.3%, and the frequency of the persistent neurologic deficits that remain over 7-10 days is 0.4%-0.5%. On the other hand, all neurologic complications of balloon test occlusion BTO have been reported in 0%-8.3% and especially in 1.6%-1.7% of symptomatic neurologic complications. There are a few reports concerning a seizure related to cerebral angiography and BTO. We report a case of prolonged seizures and left hemiparesis during and after BTO of the right internal carotid artery. The patient showed repeated focal seizures and prolonged left hemiparesis lasting for approximately 2 months. Computed tomography and magnetic resonance imaging demonstrated no abnormal findings. Suspected mechanisms of seizure were a cerebral blood flow change induced by BTO and neurotoxicity of accumulated contrast medium. A combination of prolonged focal seizures and subsequent hemiparesis is a rare complication of BTO, which should be taken into consideration during BTO.
