Aneurysm of the vein of Galen is a rare intracranial vascular malformation. It is known to have diverse manifestations and varying severity. Four cases with different modes of presentation and outcome are reported. A mortality of 50 per cent was encountered. Among the survivors, one had neurologic sequelae whereas the other had attained age-appropriate developmental milestones. The former was a rare case of spontaneous thrombosis of the aneurysm while the latter was a boy who underwent therapeutic embolization.
In patients heavily pretreated with myelosuppressive chemotherapy or irradiation, Granulocyte colony stimulating factor (G-CSF) may fail to mobilize stem cells from the bone marrow. Plerixafor is emerging as a reliable alternate option in such situations in adult patients. Robust data in support of the high efficacy and safety of plerixafor are available in adults. Very little evidence is available on the usefulness of this drug among children. We report our experience with plerixafor usage on 5 occasions in pediatric patients, with a success rate of 60%. No significant side effects were encountered in any patient.
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.
