Abstract

A 35-year-old male experienced a sudden onset of severe headache. A CT scan revealed subarachnoid hemorrhage. By cerebral angiography, he was diagnosed as having a ruptured right vertebral artery dissecting aneurysm CVADA). It was successfully treated by endovascular occlusion of the affected site, including the aneurysm and parent artery, by using detachable coils. A follow-up angiography obtained seven months after the first treatment revealed the recanalization of the right vertebral artery and dissected aneurysm in an antegrade fashion. A skull X-ray image was useful for detecting the change in appearance of the coils. The second embolization was successfully performed in the same manner. Based on this rare case, the authors emphasize that a careful angiographic analysis and complete internal trapping of the dissecting site are important in the treatment of the ruptured VADA.
