內頸動脈 閉鎖에 關聯된 腦底部 異常 血管網(2例의 症例報告) = Abnormal Cerebrovascular Network in the Brain Base Related to the Occlusion of the Internal Carotid Arteries.(Report of 2 Case)

다국어 초록 (Multilingual Abstract)

In these years, Japanese neurosurgeons have reported number of disorders related to the occlusion of the internal carotid arteries in Japanese race.
The typical angiographic picture is the occlusion or narrowing of the internal carotid arteries with the angiomatous abnormal vascular network at the base of brain. Those were called with many synonyms such as the occlusion of the circle of Willis, telangiectasis, vascular malformation or cerebral retemirabile.
Since the authors nave observed such two patients in Korean women recently, the clinical findings and the carotid angiographic features of the cases were presented.
One case was 27 year-old female and the other was 62-year-old female. Both of the cases had the primary subarachnoid hemorrhage and there was no other neurological deficits than menJngeal irritation signs.
They were recovered with the conservative treatment.
The angiographic pictures of case one revealed the bilateral occlusion of the carotid arteries at end of the siphon with the presence of abnormal vascular network in the brain bases bilaterally and the other case showed the bilateral occlusion of the carotid arteries at the end of the siphon but abnormal vascular network was seen only in the left side.
In addition to the report of the cases, references for the kind of those disorders, essentially for the discussion of their etiology and their nature, were reviewed.
