Platinum coil treatment of complex aneurysms of the vertebrobasilar circulation.

Two patients with complex aneurysms of the vertebrobasilar system were treated using platinum coils. During these sessions, 22 coils were placed in a basilar tip aneurysm in a 48-year-old woman. Almost total occlusion of the lumen was achieved, excepted in the area from which the right posterior cerebral artery arose. A large fusiform vertebral artery aneurysm in a 6-year-old boy was treated using 16 coils, which partially occluded the lumen at initial embolization. Follow-up angiography 2 weeks later revealed almost complete occlusion of the lumen with preservation of the vertebral artery. Our experience indicates that coil embolization of complex intracranial aneurysms is an acceptable treatment alternative to surgery or to a detachable balloon.

Computed tomography in a primate stroke model using selective balloon catheter arterial occlusion.

Ten heparinized nonhuman primates (rhesus monkeys and Papio maryumaya baboons) were subjected to temporary occlusion of an insular branch of the middle cerebral artery with a balloon catheter. An infarct was created. The lesions were monitored in vivo by computed tomography performed at intervals for 1 year. Animals were sacrificed and the lesions examined histologically. The technique obviates the disadvantages of surgical reaction, intravascular thrombosis, and gross cerebral edema observed in prior animal stroke models.

Multiple axis image reconstruction from axial transverse data.

The technique for alternate axis reconstruction from axial transverse computed tomography data is presented. The utility of the method as an adjunct to diagnosis, radiotherapy treatment planning, and tumor biopsy is discussed. The relative radiation dose and resolution characteristics between this and other methods are compared.

Vascular injury and penetrating facial trauma.

Three patients with gunshot wounds to facial and vascular structures were described. They demonstrate the importance of angiography in the acute care phases of treatment. In one case, angiography lead to eventual surgical management of an arteriovenous fistula. The other two cases described arterial injury that required careful surgical follow-up to detect delayed complications.

Subependymal and intraventricular hemorrhage in neonates. Early diagnosis by computed tomography.

Computed tomography was used to evaluate subependymal and intraventricular hemorrhage in 11 formalin-fixed brains obtained at autopsy from newborn infants from a population with a known high incidence of cerebral hemorrhage. After scanning, the brains were step-sectioned at levels corresponding to those of the scans. Subependymal and/or intraventricular hemorrhage was demonstrated in 6 of the 11 brains. There was a very close correlation between the scan images and the gross pathological findings in the affected brains. The authors conclude that computed tomography is an accurate method for the diagnosis of neonatal cerebral hemorrhage.
