Unusual Clinical Course of Giant Vertebral Artery Aneurysm after Proximal Artery Embolization: Case Report / 대한뇌혈관외과학회지

The authors present the case of a patient who suffered from cerebellar dysfunction, radiographically documented brainstem compression, and neurological deterioration after proximal artery occlusion in a giant vertebral artery aneurysm. Symptom resolution was achieved after complete embolization of remained lumen of aneurysm. The cause of neurological deterioration is brainstem compression due to mass effect of the aneurysm. In order to avoid this fatal complication, it is necessary to determine appropriate therapy for the vertebral artery giant aneurysm by evaluating cerebral blood flow and other factors about growth of aneurysm.
