OBJECTIVE AND IMPORTANCE Subarachnoid hemorrhage caused by an isolated dissection of the proximal portion of the posteroinferior cerebellar artery (PICA) is a rare problem. The optimal treatment to use for patients presenting with this clinical scenario varies and therefore is controversial in the literature. We report a patient in whom this problem was(More)
OBJECTIVE The advantage of anterior column support and fusion in addition to pedicle fixation in patients with degenerative spinal disorders has become increasingly clear. With the increase in popularity of this treatment, a variety of techniques have been used to achieve the goal of anterior column support, fusion, and segmental instrumentation. Posterior(More)
OBJECT The purpose of this study was to assess the durability and completeness of pain relief in patients treated using stereotactic gamma knife surgery (GKS) for trigeminal neuralgia (TN). METHODS Thirty-eight patients with refractory TN were treated with stereotactic GKS. All patients received a prescription radiation dose of 35, 40, or 45 Gy to the 50%(More)
BACKGROUND Traumatic intracranial pseudoaneurysms in children are typically the result of blunt or penetrating head injury. There are isolated reports of pseudoaneurysm as the result of intracranial aneurysm surgery in both adults and children. Treatment of these lesions, both surgically and endovascularly, can be complicated due to the known variability of(More)
Isolated dissections of the posterior inferior cerebellar artery (PICA) are rare. Thus, no large series of cases have been reported in the literature. Due to limited knowledge regarding the natural history of these lesions and the lack of high-quality evidence supporting various treatment options, management is controversial and practice parameters are ill(More)
PURPOSE The authors report the endovascular treatment of intracranial stenosis in six patients with moyamoya-type collaterals. PATIENTS All patients previously had experienced a stroke or transient ischemic attack. Lesion locations included a unilateral M1-segment lesion in five patients; and ipsilateral internal carotid artery (ICA)-T, M1 and A1 lesions(More)
Prophylactic inferior vena cava filter (IVCF) placement is advocated in some high-risk groups. We sought data regarding safety and efficacy for prophylactic IVCF placement in patients at high risk for venous thromboembolism (VTE) following major spinal reconstruction. Seventy-four spine surgery patients with contraindication to anticoagulation (44 females,(More)
OBJECTIVE To report a series of patients with aneurysmal subarachnoid hemorrhage (SAH) and associated intracranial hematoma (ICH) who underwent coiling of the aneurysm followed immediately by open surgical decompression with evacuation of the hematoma. METHODS With the hypothesis that aneurysm coiling before hematoma evacuation may simplify surgery,(More)
The concept of flow diversion is based on placing a stent across the neck of an intracranial aneurysm, which then results in flow away from the aneurysm, inducing thrombosis and occlusion of the aneurysm over time. Modern flow diverters, such as the Pipeline embolization device, are currently used for unruptured anterior circulation aneurysm. As the use and(More)
INTRODUCTION Craniopharyngiomas are known for an irregular growth pattern and extension into the retrochiasmatic space with adherence to adjacent structures. We describe the use of the transciliary supraorbital approach (eyebrow approach) for resection of craniopharyngiomas with retrochiasmatic extension. METHODS Our clinical database was reviewed to(More)
