| Outline of Final Research Achievements |
Balloon occlusion test has been used for the evaluation of the tolerance against unilateral internal carotid artery occlusion. The conventional balloon occlusion test has required the measurement of the cerebral blood flow and clinical condition during the occlusion of the internal carotid artery. In this research, we elucidated a strong correlation between the angiographic circulation time and the cerebral blood flow during the balloon occlusion test. This result would make the balloon occlusion test safer and easier. This method enables us to estimate the tissue blood flow according to findings of the catheter angiogram and would be useful for the understanding pathophysiology of diseases in other tissues and organs.
Delayed cerebral ischemia after aneurysmal subarachnoid hemorrhage in one of poor prognostic factor. In this research, we revealed the usefulness of the real-time cerebral blood flow measurement for the prevention of the delayed cerebral ischemia.
