[A case of giant aneurysm associated with vertebral fenestration (author's transl)].
A case of giant aneurysm associated with vertebral fenestration was reported. A 18-year-old female had complained of visual disturbance of left eye for past 2 years without headache, nausea and vomiting. Neurological examinations revealed normal except for optic atrophy on the left side. Physiological examinations were normal. Skull plain films showed the small calcification at the left supraclinoid region. Left common carotid angiograms revealed a giant aneurysm at left internal carotid artery measuring 4 X 2 X 2 cm in size, and left middle cerebral artery was poorly visualized. Vertebral angiograms showed the fenestration at left craniospinal junction. Computerized tomograms showed a round, granular high density lesion, and this lesion was clearly homogenously enhanced by contrast medium. It was considered that the direct surgery to this aneurysm might be impossible, because the neck of the aneurysm was located at extradural portion. Ligation of her common carotid artery was performed with Selverstone clamp. Her postoperative course was uneventful, and the postoperative angiograms revealed the reduction of the size of aneurysm. The etiological hypotheses of these cerebral vascular anomalies were briefly discussed.
