BACKGROUND Indocyanine green (ICG) angiography is commonly used to map the vascular configuration of cerebral arteriovenous malformations (AVMs) during resection. OBJECTIVE To determine whether ICG improves rates of resection and clinical outcomes. METHODS A retrospective chart review was done for all patients undergoing resection of an AVM by the(More)
The history and evolution of surgical strategies for the treatment of Kleeblattschädel deformity are not well described in the medical literature. Kleeblattschädel anomaly is one of the most formidable of the craniosynostoses, requiring a multidisciplinary team for surgical treatment. The initial descriptions of this cloverleaf deformity and the evolution(More)
Remarkable advances and changes in the landscape of neurovascular disease have occurred recently. Concurrently, a paradigm shift in training and resident education is underway. This crossroad of unique opportunities and pressures necessitates creative change in the training of future vascular neurosurgeons to allow incorporation of surgical advances, new(More)
In the modern era, neuroendoscopy has had an increasingly prominent role in neurosurgery. As attention has focused the development of minimally invasive surgical methods, neuroendoscopy has advanced both as an independent treatment modality for various neurologic disorders and as an adjunct to microneurosurgery. Neuroendoscopy is distinct from traditional(More)
BACKGROUND Deep-seated periventricular cavernous malformations of the basal ganglia or thalamus can be approached via an interhemispheric craniotomy. OBJECTIVE To determine surgical efficacy and clinical outcomes of the contralateral interhemispheric approach. METHODS Retrospective chart review was performed on patients undergoing an interhemispheric(More)
BACKGROUND Bow hunter's syndrome is a rare vascular phenomenon characterized by insufficiency of the posterior cerebral circulation induced by rotation of the head within normal physiologic range. The neurosurgical literature on evidence-based diagnosis and management of the disease is scarce, and reports are largely limited to case studies. METHODS A(More)
BACKGROUND Use of the operating microscope has become pervasive since its introduction to the neurosurgical world. Neuronavigation fused with the operating microscope has allowed accurate correlation of the focal point of the microscope and its location on the downloaded imaging study. However, the robotic ability of the Pentero microscope has not been(More)
Hemifacial spasm (HFS) due to direct compression of the facial nerve by a dolichoectatic vertebrobasilar artery is rare. Vessels are often non-compliant and tethered by critical brainstem perforators. We set out to determine surgical strategies and outcomes for this challenging disease. All patients undergoing surgery for HFS secondary to vertebrobasilar(More)
In this paper, the authors' aim is to provide an evidence-based review of primary and secondary ischemic stroke prevention guidelines covering most of the common risk factors and stroke etiologies for the practicing neurosurgeon. The key to stroke prevention is in the identification and treatment of the major risk factors for stroke. These include(More)
