OBJECT The histopathological characteristics of aneurysms obtained at autopsy or surgery 3 days to 54 months after being treated with Guglielmi detachable coils (GDCs) were assessed. METHODS Seventeen aneurysms were obtained at autopsy and one was removed at surgery. Fourteen were examined histologically with the coils in situ. Naked coils embedded in an(More)
OBJECTIVES In vivo cartilage contact deformation is instrumental for understanding human joint function and degeneration. This study measured the total deformation of contacting articular cartilage in the human tibiofemoral joint during in vivo weight-bearing flexion. METHODS Eleven healthy knees were magnetic resonance (MR) scanned and imaged with a dual(More)
Cerebral ischemia is accompanied by many of the cardinal features of acute inflammation such as neutrophil and platelet activation and accumulation. We sought to determine whether circulating neutrophils or platelets contribute to brain injury in a rabbit model of thromboembolic stroke that includes a fixed duration of superimposed systemic hypotension. We(More)
Continuous cerebrospinal fluid (CSF) drainage may be used in the treatment CSF fistula. The procedure, however, is not without risk. Marked gradients between the intracranial and intraspinal CSF pressures and intravasation of air through an unsealed fistula may produce serious neurological problems. The use of continuous CSF drainage requires an alert,(More)
We present three patients who were admitted to our institution with vertebrobasilar dolichoectasia diagnosed at CT angiography. Two patients had associated intraarterial thrombi and one patient had basilar artery dissection. Shaded surface display images were useful in showing arterial anatomy relative to the skull base. Source images and curved-reformatted(More)
Protein tyrosine phosphatase-basophil like (PTP-BL) is a large non-transmembrane protein tyrosine phosphatase implicated in the modulation of the cytoskeleton. Here we describe a novel interaction of PTP-BL with the protein kinase C-related kinase 2 (PRK2), a serine/threonine kinase regulated by the G-protein rho. This interaction is mediated by the PSD-95,(More)
OBJECTIVE The purpose of this study was to compare CT angiography with digital subtraction angiography (DSA) in the detection and measurement of intracranial aneurysms in patients with acute subarachnoid hemorrhage. SUBJECTS AND METHODS Thirty consecutive patients with recent subarachnoid hemorrhage shown by unenhanced CT scanning or lumbar puncture were(More)
OBJECT The authors retrospectively analyzed the results of their 6-year experience in the treatment of basilar artery (BA) bifurcation aneurysms by using Guglielmi detachable coils (GDCs). METHODS This analysis involved 45 BA tip aneurysms in 16 men and 29 women who ranged in age from 23 to 78 years (mean 50 years). Seventy-five percent of the aneurysms(More)
Blindness following facial trauma may occur with what appears to be a minor insult to the periorbital area. This report deals with our experience in treating five patients who had sudden blindness following frontal head trauma. Unselected optic nerve decompression was in general unrewarding in reversing blindness. However, the early administration of(More)
OBJECTIVE Cerebral vasospasm is the leading cause of morbidity and mortality in patients who are hospitalized because of aneurysmal subarachnoid hemorrhage (SAH). Recent work has suggested that activation of the complement cascade contributes to the development of cerebral vasospasm. To further examine this hypothesis, a rabbit model of SAH was employed. (More)
