[Evaluation of aortic aneurysm and dissection by abdominal echography].

Aortic dissection and aneurysm are related to increased vulnerability of the aortic wall due to arteriosclerosis. Echographic findings of aortic sclerosis include irregularity and strong punctate echoes in the intima and meandering of the aorta. Unruptured abdominal aneurysms are often found incidentally by routine echography.

[Cerebral circulation dynamics following fasudil intravenous infusion: a CT perfusion study].

Using CT perfusion studies we evaluated changes in the cerebral circulation before and after the intravenous administration of fasudil 60 mg in 8 patients 7 to 14 days after a subarachnoid hemorrhage. The mean duration to the peak of the time-density curve and the average peak value did not change. In areas with cerebral blood perfusion (CBP) less than 40 ml/100 g/min, the CBP increased from 34.

[Intra-arterial administration of fasudil hydrochloride: duration of action].

Intra-arterial infusion (IA) of fasudil hydrochloride for cerebral vasospasm is performed in many institutions and is associated with few side effects. Nonetheless, as optimum dose and duration of action remain unknown, the present study aimed to clarify these variables. We performed intra-arterial injection of fasudil hydrochloride for eight patients with cerebral vasospasm 7-13 days after subarachnoid hemorrhage.
