BACKGROUND Previous studies on stroke after coronary artery bypass grafting (CABG) provide limited data about the timing (early vs delayed) of this event and findings of brain imaging analysis. This information is of significant importance because it provides insight into the etiology of stroke, potentially allowing the development of preventive measures.(More)
The aim of this study was to analyze the incidence, topography, and mechanisms of stroke, independent predictors, and late outcome after cardiac valve operations. We retrospectively analyzed prospectively collected data from 2,808 patients (mean age 63 +/- 15 years, n = 1,610, 55% men) who underwent valve surgery with or without concomitant coronary artery(More)
OBJECTIVE Previous studies of the epidemiology of stroke in patients undergoing cardiac surgery have been based primarily on patients having coronary bypass surgery and therefore have limited applicability to the more heterogenous populations seen in the current era. We examine the epidemiology of stroke after cardiac surgery in a contemporary surgical(More)
BACKGROUND Neurological impairment is a major source of morbidity and mortality following orthotopic liver transplantation (OLT). We reviewed our experience with neurologic complications among our first 463 consecutive adult OLT recipients. METHODS Between September 1988 and October 1993, 463 adult patients underwent OLT. Data on incidence, time of onset,(More)
A 30-year-old parturient requested epidural analgesia during labor. Immediately after the epidural space was presumably identified using the loss-of-resistance-to-air technique, she reported severe back pain, followed by neck pain, which progressed to severe unrelenting headache. An emergency computerized tomographic (CT) scan performed during labor showed(More)
Six weeks after liver transplantation, a 51-year-old man developed a slowly progressive hemiparesis with deteriorating mental status and seizures. Successive computed tomography (CT) scans of the brain revealed unilateral nonenhancing white matter lucencies that gradually coalesced and progressed to both hemispheres. Brain biopsy results were consistent(More)
Primary intraosseous hemangiomas are benign, vascular malformations that account for approximately 1% of all primary bone neoplasms. These tumors are mostly found in vertebral bodies and are rarely seen in the calvarium, where they represent 0.2% of bony neoplasms. When found in the skull, they tend to present with vague symptoms and do not have the typical(More)
BACKGROUND Mutism/speech apraxia has been well documented as a toxic effect of cyclosporine after liver transplantation but has been reported only rarely with tacrolimus. Brain imaging with magnetic resonance or computed tomography has failed to demonstrate abnormalities in affected patients. METHODS We present the first example of an acute onset of loss(More)
Neurologic complications are frequent after liver transplantation and are the cause of significant morbidity and mortality. A substantial proportion of the neurologic complications encountered after transplant is iatrogenic--the consequence of the harsh therapeutic interventions required to maintain function of the transplanted liver. The preoperative(More)
