BACKGROUND AND PURPOSE To explore relationships among gender, body size, neck size, and the diameters of the common carotid artery (CCA) and internal carotid artery (ICA). METHODS Using multivariate regression, the best predictors of sonographic diameters of CCA and ICA were determined based on age, height, weight, body mass index, body surface area, neck(More)
To determine the performance of an artificial neural network in transcranial color-coded duplex sonography (TCCS) diagnosis of middle cerebral artery (MCA) spasm. TCCS was prospectively acquired within 2 h prior to routine cerebral angiography in 100 consecutive patients (54M:46F, median age 50 years). Angiographic MCA vasospasm was classified as mild (<25%(More)
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)
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)
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)
