OBJECTIVE Pediatric cerebral aneurysms are rare. There are very few recent studies that focus on the multidisciplinary treatment of ruptured aneurysms. We reviewed our pediatric endovascular and surgical experience with ruptured cerebral aneurysms. METHODS Pediatric patients aged 16 years and younger who were admitted with a diagnosis of aneurysmal(More)
BACKGROUND AND PURPOSE Permanent balloon occlusion (PBO) of the carotid artery has been previously shown to be an effective means to treat carotid blowout syndrome (CBS). However, despite the effectiveness of this endovascular technique, concern remains regarding its potential for producing delayed cerebral ischemic complications in 15% to 20% of patients.(More)
BACKGROUND Cerebral venous sinus thrombosis (CVST) is a rare form of stroke. Although increased intracranial pressure is a well-described complication of CVST, hydrocephalus has rarely been reported. CASE We present the case of a 49-year-old woman who presented with one week of headache, vomiting, and progressive neurologic deterioration leading to coma.(More)
BACKGROUND The prevalence of intracranial aneurysms is approximately 2% with an annual rupture rate of 0.7%. OBJECTIVE We describe our initial feasibility experience using a new double-lumen balloon catheter for single-catheter balloon-assisted coil embolization of wide-neck intracranial aneurysms. METHODS Two patients with large wide-neck intracranial(More)
Background. Cervicocephalic arterial dissection (CCAD) is rare in the postpartum period. To our knowledge this is the first reported case of postpartum angiopathy (PPA) presenting with ischemic stroke due to intracranial arterial dissection. Case. A 41-year-old woman presented with blurred vision, headache, and generalized seizures 5 days after delivering(More)
OBJECTIVE AND IMPORTANCE To describe the clinical presentation and endovascular management of peripheral aneurysms of the lateral posterior choroidal artery. Aneurysms in this location are exceptionally rare and optimal treatment may be difficult. CLINICAL PRESENTATION Two patients with peripheral aneurysms of the distal portion of the lateral posterior(More)
Vertebral hemangiomas are common entities that rarely present with neurological deficits. The authors report the unusual case of a large L-3 vertebral hemangioma with epidural extension in a 27-year-old woman who presented with hip flexor and quadriceps weakness, foot drop, and leg pain. The characteristics of the mass on magnetic resonance imaging(More)
INTRODUCTION Reversible cerebral vasoconstriction syndrome (RCVS) is a rare vasculopathy of unknown etiology. Ischemic stroke and intracerebral hemorrhage are well-documented sequelae, but subarachnoid hemorrhage is an uncommon complication of RCVS. METHODS AND RESULTS We report six cases of RCVS associated with subarachnoid hemorrhage. Two cases occurred(More)
To our knowledge, the use of transdermal nitroglycerin ointment (Nitropaste) in the setting of intracranial vasospasm has not been described in the peer-reviewed literature. Five patients with intracranial vasospasm induced by subarachnoid hemorrhage were evaluated angiographically both before and after application of Nitropaste. All cases exhibited mild to(More)
INTRODUCTION Intra-arterial papaverine (IAP) is used to treat symptomatic cerebral vasospasm following aneurysmal subarachnoid hemorrhage (SAH). IAP, however, can increase intracranial pressure (ICP). In this study we examined whether IAP alters brain oxygen (BtO2). METHODS Poor clinical grade (Hunt & Hess IV or V) SAH patients who underwent continuous(More)
