Abstract
A Case report of cerebral arterial tortuosity and ectasia with saccular aneurysm is rare. We presented a case of remarkable carotid arterial tortuosity and megadolicho basilar artery with aneurysm of the anterior communicating artery.
The patient was a 49-years-old woman who suffered from initial stroke of subarachnoid hemorrhage. At first, the original site of subarachnoid hemorrhage was assumed from the megadolicho basilar artery, because the aneurysm of anterior communicating artery was failed to notice by the exaggerated elongation of bilateral C2 and A1 portions. At last, the aneurysm was discovered, and was definited as a hemorrhage site when the neck of aneu-rysm was clipped by direct operation.
The etiology and significance of these tortuosity and ectasia are still matters of contro-versy. In our patient, we postulate that the etiology of cerebral arterial tortuosity and ectasia has a basis of congenital defective lesion of vessels which may become exaggerated with aging, consequently the frequency that cerebral arterial tortuosity and ectasia are combined with aneurysms, may increase in future. We believed that such a case must be proceeded more precise investigation for cerebral angiogram.
A new method of the small area X-ray irradiation was more effective for a diagnosis of cerebral arterial tortuosity and ectasia with saccular aneurysm, was introduced.
