Contrast-enhanced ultrasonography of the carotids has recently emerged as a complementary examination to conventional carotid Doppler ultrasonography. It is an examination providing improved visualization of the vascular lumen, more accurate and detailed delineation of the vascular wall, and identification of atherosclerotic plaques. Moreover,(More)
Relapsing polychondritis is a rare autoimmune disease characterized by inflammation of cartilaginous tissues. It may be associated with systemic and cerebral vasculitis and exceptionally with ischemic stroke. Brain infarction associated with internal carotid artery thrombus, in a setting of relapsing polychondritis, has never been reported. We present a(More)
OBJECTIVE The study was conducted to determine the effect of carotid angioplasty and stenting (CAS) on the hemodynamic parameters and cerebrovascular reactivity (CVR) of the ipsilateral middle cerebral artery (MCA) and examine the relation between preprocedural exhausted CVR and perioperative neurologic events. METHODS The study included 29 patients with(More)
BACKGROUND Neurolymphomatosis describes the malignant lymphomatous infiltration of nerves. METHODS We encountered a unique case of a 47-year-old patient with non-Hodgkin's lymphoma presenting with bilateral sensorineural hearing loss, vestibular dysfunction and bilateral facial nerve palsy. RESULTS Magnetic resonance imaging demonstrated enhancement and(More)
Carotid atherosclerotic disease constitutes a major modern health problem whose diagnosis primarily relies on imaging. Grading of stenosis has been long used as the main factor for risk stratification and guiding of management. Nevertheless, increasing evidence has shown that additional plaque characteristics such as plaque composition and surface(More)
The records of nine female intact dogs with histologically confirmed uterine tumors were reviewed retrospectively, and the related radiographic and ultrasonographic signs of the lesions detected were recorded. Radiography revealed a soft-tissue opacity between the urinary bladder and colon in six of seven dogs with uterine body and/or cervical tumors, and a(More)
For cardiothoracic surgeons prosthetic graft infection still represents a difficult diagnostic and treatment problem to manage. An aggressive surgical strategy involving removal and in situ replacement of all the prosthetic material combined with extensive removal of the surrounding mediastinal tissue remains technically challenging in any case.
