T technology of building aqueducts carrying the water in near and distant watersheds together with giant cisterns that store the water to meet the water need of the public in big settlements is a gift of Rome to the history of architecture. The most beautiful example of engineering science and water architecture in İstanbul is Yerebatan Palace that has also become famous as a large basilica cis...

Trigeminal neuralgia was the presenting symptom in two patients with aqueduct stenosis, hydrocephalus, and raised intracranial pressure. Treatment of the hydrocephalus resulted in the remission of pain in both patients.

CSF normally flows back and forth through the aqueduct during the cardiac cycle. During systole, the brain and intracranial vasculature expand and compress the lateral and third ventricles, forcing CSF craniocaudad. During diastole, they contract and flow through the aqueduct reverses. Hyperdynamic CSF flow through the aqueduct is seen when there is ventricular enlargement without cerebral atro...

Gradient-echo MR sequences are more sensitive to flow phenomena than spin-echo sequences are. We investigated aqueductal CSF flow by fast multiphase imaging. Fast multiphase imaging offers the opportunity to perform a dynamic study of fluid motion that is synchronous with the cardiac cycle. A section perpendicular to the cerebral aqueduct was imaged in 18 healthy volunteers. Serial, gated (ever...

INTRODUCTION In the present case we report on the mismanagement of a patient misdiagnosed with otosclerosis, who was subsequently found to have enlarged vestibular aqueduct syndrome bilaterally. This highlights the need to not only be vigilant in pre-operative assessment of otosclerosis but also in post-operative investigations of stapedectomy failures. CASE PRESENTATION Our patient, a 56-yea...

In order to study the stress and deformation characteristics of Jigongzui U-shaped thin shell aqueduct structure, element in ANSYS is proposed establish three-dimensional finite model for numerical calculation, relevant mechanical parameters are obtained by detecting depth concrete carbonization. The simulated results show that: (1) carbonization reached 20mm, accounting about 20% total thickne...

We present the first demonstration of cardiac-gated MRI measurements of pulsatile cerebrospinal fluid (CSF) flow in both control rats and in a new rat model of communicating hydrocephalus (HC). Such measurements are extremely valuable as a non-invasive tool for monitoring functional changes in intracranial dynamics over the course of the development and progression of HC. Images were taken usin...

OBJECTIVE A group of 20 patients with large vestibular aqueduct syndrome was identified at the Indiana University School of Medicine. The major objective of this study was to explore the improvements in quality of life associated with cochlear implantation in patients with large vestibular aqueduct syndrome, as well as the cost-utility of cochlear implantation in this group. SETTING A total o...
