Review Historical ArticleTranscranial minimally invasive neurosurgery for tumors.
This article considers common minimally invasive craniotomy approaches and the role of neuroendoscopy in the removal of extra-axial and intra-axial brain tumors, excluding those of the ventricle. The use of a keyhole craniotomy combined with a carefully selected trajectory can help avoid the disadvantages associated with a standard craniotomy. ⋯ Endoscopy can also be used as a surgical adjunct to improve tumor resection and to help protect neurovascular structures. Complications associated with minimally invasive tumor neurosurgery have been similar to those associated with conventional neurosurgical approaches, and available outcomes are promising.

ReviewMinimally invasive surgery (endonasal) for anterior fossa and sellar tumors.
The primary goal of any surgical approach is to adequately visualize and treat the pathologic condition with minimal disruption to adjacent normal anatomy. The work of several researchers has revealed the promise of minimally invasive endonasal neurosurgery and paved the way for broader applications of the technology. This article discusses the current state of minimally invasive endonasal techniques to address the pathologic conditions of the anterior cranial fossa and parasellar region.

ReviewComplication avoidance in minimally invasive neurosurgery.
Although minimally invasive neurosurgery (MIN) holds the potential for reducing the approach-related impact on normal brain, bone, and soft tissues, which must be manipulated in more conventional transcranial microneurosurgery, the techniques necessary to perform minimally invasive, yet maximally effective neurosurgery place significant demands on the surgeon because in many ways the more limited exposure creates a number of unique ways these operations can go wrong. Safe and effective MIN requires the conscious institution of specific alterations to the surgeon's usual operative case flow, which are designed to make specific well-known mistakes impossible or at least very unlikely. Thus, it is important for the aspiring MIN surgeons to learn from the mistakes of their predecessors and to institute patterns of behavior that prevent a repetition of these mistakes. This article provides practical information regarding known pitfalls in intraventricular and transcranial neuroendoscopic surgeries and practical methods to reduce the incidence of these complications to the lowest rate possible.

ReviewDiagnosis and management of arteriovenous malformations in children.
Arteriovenous malformation (AVM) is the most common cause of spontaneous intraparenchymal hemorrhage in children, excluding hemorrhages of prematurity and early infancy. Because most children diagnosed with an AVM undergo initial treatment emergently, the natural history of AVMs in the pediatric population is not well understood. Most pediatric AVMs do not come to clinical attention unless they hemorrhage. ⋯ Microsurgical resection remains the gold standard for treatment of accessible pediatric AVMs, especially in cases that present with intracranial hemorrhage. Newer modalities, such as embolization and radiosurgery, have provided additional tools to help children with large or deep-seated lesions that would be deemed unresectable with microsurgical techniques alone. Long-term follow-up with repeated diagnostic imaging is important despite complete obliteration of the lesion to rule out the small possibility of AVM recurrence.
