✓ The incidence of various types of intracranial hemorrhage (ICH) and the microscopic appearance of the major intracranial arteries were investigated in 112 premature infants, and related to birth weight. In none of the premature newborns, regardless of the presence of ICH, did the intracranial arteries contain true elastic elements. The wall of the basilar artery was significantly thinner in all premature infants with any kind of ICH. Within each body-weight group those with ICH had intracranial arteries with fewer reticular fibers than did those without ICH. The density of the reticular fibers in the cerebral arteries of premature neonates without ICH did not seem to depend on maturity. The authors believe that the hypoplasia of the major intracranial arteries and the reticular fiber deficiency most probably involve the whole vascular system of the brain and may predispose to hemorrhage.

Dissecting Aneurysms

Abstract Dissecting aneurysms of the intracranial arteries display vascular pathological features that appear sporadically, generally affecting young adults. The clinical features of this condition may involve both ischemic episodes and hemorrhages. Posterior circulation is affected less than the rest of the intracranial arteries, and it is extremely rare to find the posterior cerebral arteries only affected. Mortality is high in patients where the lesion is located in the posterior intracranial circulation, although dissecting aneurysms limited to the posterior cerebral arteries may, to a certain extent, be benign. We report the case of a young woman with ischemia in the territory of the posterior cerebral artery that occurred subsequent to a dissecting aneurysm that resolved spontaneously to a complete remission, both clinically and as demonstrated by angiography. A review of the literature is made, analyzing the pathogenic, clinical, angiographic, and therapeutic characteristics of such lesions.
