Shunt stenosis
WebFlow through the shunt should be of high velocity (>4 m/s) continuously throughout systole and diastole with a characteristic sawtooth Doppler spectral pattern, consistent with the continuous aortic-to-pulmonary pressure gradient. Reduced flow velocity often suggests an increase in PA pressure. Shunt stenosis can be challenging. CT scans are used to visualize the structure of the inside of the body without needing to make any incision. For the purposes of diagnosis aqueductal stenosis, a scan is performed on a patient's brain. Images showing an enlarged third ventricle along with a normally sized fourth ventricle (in a lateral view) is generally considered to be an indication of aqueductal stenosis, but this is still only presumption. CT scans are typically used after a shunt treatment in order to analyze ventricle siz…
