Eleven cases of intracranial arterial aneurysms in patients under 15 years of age, treated from 1959 to 1976, are presented. The preponderance of aneurysms at the internal carotid artery bifurcation and the peculiarities of the defects in this location are remarkable.
A direct fistula between cerebral cortical arteries and venous channels may result in an impressive aneurysm-like, saccular dilation of the venous portion. We had the opportunity to treat two children with this rare arteriovenous malformation, with excellent results. The controversy on the classification and treatment of this pathology is discussed briefly.
Ventriculoperitoneal or cyst-peritoneal shunts are the usual treatment for children with Dandy-Walker syndrome. A combined ventricular and cyst shunt is often necessary and, in some cases, multiple revisions have to be done. Two patients with this syndrome were treated with posterior fossa exploration and cyst fenestration after several shunt revisions. The procedure was well tolerated with good results in both cases. The patients' data and preliminary results are presented here.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
