introduction rhino-orbito-cerebral mucormycosis is a progressive angioinvasive fungal disorder which almost always complicates immunocompromised patients. case presentation we described a case of fulminant rhino-orbito-cerebral mucormycosis in a 65-year-old woman, who presented with progressive neurological deficits due to involvement of orbital apex and the central nervous system by local inva...

Background: β-thalassemia, a severe form of anemia, is an inherited blood disorder characterized by growth retardation, splenomegaly, and bone abnormalities. Complications related to treatment-induced iron overload also affect the quality of life of patients with major β-thalassemia. Some recent studies indicated cerebral hemodynamic disorders and increased risk of stroke in these patients. The...

Background: To evaluate the effect of oxytocin on blood circulation of fetus and uterus by Doppler ultrasound. Materials and Methods: Forty six pregnant women were assigned to receive for indication of delivery intravenous oxytocin. Doppler velocitometry before and after administration of oxytocin for umbilical,middle cerebral artery and uterine artery were performed, and Pulsatility index (PI)...

conclusions both ua and mca doppler tests were associated with some neonatal outcomes. however, sensitivity of both ua and mca assessments was low in the prediction of adverse neonatal outcomes. by the comparison of these two methods, we found that ua doppler assessment is a better predictor of neonatal outcomes. results based on the findings, poor outcomes were detected in 48 women. nearly 17....

An accessory middle cerebral artery is one variation of the intracranial vasculature that may be a source of misinterpretation by clinicians dealing with cerebrovascular diseases. We report a case of an elderly female found to have bilateral accessory middle cerebral arteries, who presented with the rupture of an aneurysm of the anterior part of the circle of Willis. Accessory middle cerebral a...

Course and distribution information on arteries in the rat rhinencephalon was not found in the literature. Such data are useful for designing experiments and interpreting findings, tracing nerve fibers on or to intracerebral vessels, and in considering routes for diffusion or transport of intracerebral injected agents. Adult rats were perfused with silicone rubber and many brains were cleared i...

Fourteen accessory middle cerebral arteries demonstrated on angiography were reviewed relative to the pertinent literature. The anomalous vessel follows a fairly constant pattern in terms of origin, course, and distribution, and it frequently gives rise to basal perforating arteries. It is suggested that the vessel represents a persistent anastomosis between the anterior and middle cerebral art...

BACKGROUND AND PURPOSE Cerebral vasoreactivity is an important indicator of the reserve capacity of the cerebral circulation. To make a quantitative analysis of cerebral vasoreactivity in individual major arterial territories, we evaluated the response to acetazolamide using three-dimensional time-of-flight magnetic resonance angiography. METHODS We examined 10 healthy volunteers and 6 patien...
