We report the case of a child with Moyamoya disease during a cerebral angiography procedure in which the effects of propofol on the cerebral perfusion were seen to be different compared with isoflurane. We suggest propofol was associated with a better preservation of cerebral circulation compared to isoflurane in this case of Moyamoya, as it maintained blood supply to the watershed areas.
View Article and Find Full Text PDFA measurement system is proposed to evaluate reconstructive effects of carotid stents on the geometry of the carotid bifurcation and the course of the internal carotid artery. To describe deviations of the stenotic internal carotid artery (ICA) from the extended axis of the common carotid artery (CCA) the CCA-ICA angle is measured between the CCA midaxis and the midaxis of the stenotic ICA segment. Maximal extensions of ICA tortuosities perpendicular to the course of the CCA axis are defined as ICA offset.

Design: Prospective, controlled animal study.
Setting: University-affiliated research laboratory.
Cerebral vasospasm remains a devastating medical complication of aneurysmal subarachnoid hemorrhage (SAH). It is associated with high morbidity and mortality rates, even after the aneurysm has been secured surgically or radiologically. A great deal of experimental and clinical research has been conducted in an effort to find ways to prevent this complication.
View Article and Find Full Text PDFBackground And Purpose: We sought to quantitatively and qualitatively evaluate the release of atheromatous plaque debris induced by carotid stenting procedures.
Methods: Eight patients with severe carotid atheromatous stenoses were treated by stent implantation under distal balloon protection. Blood samplings were obtained after stent deployment in the blood pooled below the inflated protection balloon.
