Gamma knife surgery for arteriovenous malformations involving the corpus callosum.
The purpose of this study was to evaluate the safety and efficacy of gamma knife surgery (GKS) for the treatment of arteriovenous malformations (AVMs) involving the corpus callosum. ⋯ Gamma knife surgery is a safe and effective treatment for selected patients with AVMs involving the corpus callosum, and it carries a low risk of damaging adjacent critical vascular structures. Even ruptured AVMs with relatively large diameter can be successfully treated, especially in younger patients, with minimal morbidity and a low risk of repeated hemorrhage.

Long-term outcomes in patients with vestibular schwannomas treated using gamma knife surgery: 10-year follow up.
Gamma knife surgery (GKS) has been a safe and effective treatment for vestibular schwannomas in both the short and long term, although less is known about long-term outcomes in the past 10 years. The aim of this study was to clarify long-term outcomes in patients with vestibular schwannomas treated using GKS based on techniques in place in the early 1990s. ⋯ Gamma knife surgery remained an effective treatment for vestibular schwannomas for longer than 10 years. Although treatment failures usually occurred within 3 years after GKS, it is necessary to continue follow up in patients to reveal delayed tumor recurrence.

Case ReportsTemporary symptomatic swelling of meningiomas following gamma knife surgery. Report of two cases.
In two patients in whom gamma knife surgery was performed for meningiomas clinically significant volume increases were observed in the first 3 months after treatment. Clinical examination and various imaging studies form the basis of the report in these patients. In each case, the volume increase was temporary.

Case ReportsMultiple cerebral aneurysms in a neonate: occlusion and rupture.
Aneurysmal subarachnoid hemorrhage in a neonate is exceedingly uncommon. The authors report the case of a neonate with a large anterior communicating artery aneurysm, accessory left middle cerebral artery aneurysm, and left internal carotid artery (ICA) fusiform aneurysm. ⋯ The large aneurysm was treated with detachable coils and the patient made a significant recovery. Of the 15 case reports of cerebral aneurysms in neonates that have been published, none has contained a description of multiple aneurysms or a discussion of endovascular treatment.

How low can you go? Intracranial pressure, cerebral perfusion pressure, and respiratory obstruction in children with complex craniosynostosis.
Elevated intracranial pressure (ICP) is a well-recognized complication affecting children suffering from complex forms of craniosynostosis. The effects of ICP, including those on vision, and the underlying mechanisms involved remain uncertain. The aim of this study was to examine the relationships among ICP, cerebral perfusion pressure (CPP), and the episodic alterations in respiratory obstruction that are common in children with craniosynostosis. ⋯ The findings of this study indicate that ICP, CPP, and respiratory obstruction interact in a vicious cycle, an observation that helps explain the pattern of plateau waves of elevated ICP characteristic among children with complex forms of craniosynostosis. The data gathered in this series revealed levels of CPP considerably lower than those described previously in clinical reports. Such reductions in CPP most likely contribute to the neurological, cognitive, and ophthalmological morbidity from which these children suffer frequently; therefore, the results of this study have important implications for the management of children with complex forms of craniosynostosis as well as for our understanding of the control of cerebral blood flow in general.
