A CASE WITH BILATERAL INTERNAL CAROTID ARTERY OCCLUSION

The disease which are caused by the narrowing or obstruction of main arteries supplying brain with unknown etiology has recently been noticed in neurological clinics. One is the disease with sponteneous internal carotid occlusion which is noticed by Shimizu & Takeuchi, and the other is the disease with abnormal intracranial vascular networks which has been noticed in these several years in Japan. Both of the disease are noticed and investigated especially by Japanese neurosurgeons. A case of 51year-old male patient which showed clinically Denny-Brown Syndrom since recent 6 years was reported. The angiograms showed bilateral complete occlusion at the proximal cervical portion of internal carotid arteries and also showed extensive collateral circulation similary seen in a disease with abnormal intracranial vascular networks. Histological studies by biopsy is carried out and it appeared that main lesion was not at intima but at media accompanying increment of connective tissue and fragmentation of elastic fibres. Moreover, the partial fragmentation of internal elastica and the thickning of intima was also observed. From it's clinical symptoms and it's site of occlusion of arteries, this case resembles with a spontaneous internal carotid occlusion, but from angiographical studies, this rather resembles with a disease with abnormal intracranial vascular networks and histologically, the findings are completelydifferent from them in this case. The cases which are on similar line have not been reported yet.
