OBJECTIVES We sought to identify the incidence, predictors, and clinical implications of cerebrovascular accidents (CVAs) after percutaneous coronary interventions (PCIs). BACKGROUND Cerebrovascular accidents after PCI, although rare, can be devastating. Limited information exists regarding the characterization of this complication. METHODS The study(More)
PURPOSE To determine the association of intracranial arterial fenestration and aneurysms. METHODS We retrospectively reviewed 5,190 cerebral angiogram reports and identified 37 patients with arterial fenestrations. RESULTS These 37 patients had 38 fenestrated arteries: 16 basilar, 10 vertebral, nine middle cerebral, and three anterior cerebral arteries.(More)
We describe two cases in which balloons were used to aid in the occlusion of intracranial aneurysms with Guglielmi detachable coils. In both patients, initial attempts to place coils within the aneurysmal sac failed, as the loops of the coil repeatedly protruded through a wide aneurysmal neck into the parent vessel. Temporary balloons placed across the neck(More)
Local spinal pain and radiculopathy are common conditions that debilitate millions of Americans annually. Most cases are successfully treated conservatively with rest or physical therapy. Chiropractic manipulation or, in some cases, surgery may also be performed. Percutaneous injection has been used for spinal pain management for many years, but many of(More)
True synovial cysts of the spine are rare though they are included in the differential diagnosis of an extradural lesion in a patient with radicular pain or pain localized in the involved level of the spine. We present the second reported case of a synovial cyst of the cervical spine, and review the literature. A 42-year-old woman was in good health until 2(More)
Gliosarcoma is a brain neoplasm that is being recognized with increasing frequency. We discuss the radiographic findings in 14 pathologically proven cases. At angiography in nine cases, four showed mixed dural and pial vascular supply to the lesion. Early cortical venous drainage, irregular tumor vessels, and a prominent vascular stain with well-defined(More)
The authors report six new cases of epidural lipomatosis--a rarely described entity characterized by increased extradural fat within the spinal canal causing compression of the spinal cord and neurologic deficits. Five of the six patients had a history of chronic steroid use. Myelography of the thoracic spine, followed by computed tomography (CT), was(More)
Paragangliomas, also known as glomus tumors or chemodectomas, are tumors arising from chemoreceptor tissue (paraganglia), which are neural crest in origin and found in higher concentration along the glossopharyngeal and vagal cranial nerve. Three types of paragangliomas are related with the temporal bone: glomus tympanicum, glomus jugulare, and glomus(More)
With the widespread prevalence of back pain, and approximately 200,000 lumbar spine operations annually in the United States, imaging of the postoperative lumbar spine has become a major diagnostic issue. The many causes of the failed back surgery syndrome make the diagnosis of the etiology of the patient's symptom complex very important to the treating(More)
