<h3>BACKGROUND AND PURPOSE:</h3> Aqueductal CSF stroke volume (ACSV) measured by phase-contrast MR imaging is a tool for selection of surgical patients with idiopathic normal-pressure hydrocephalus (iNPH). The aim the present study was to investigate whether there relationship between clinical outcome and changes in ACSV iNPH who have been shunted. <h3>MATERIALS METHODS:</h3> Sixty-five shunted underwent evaluation measurements 7–30 days before 1, 3, 6, 12 months after surgery. <h3>RESULTS:</h3> Two were excluded from occurrence perioperative complication. In group 35 clinically improved patients, mean preoperative (157.01 μL) decreased 18% one month ventriculoperitoneal shunt (VPS) ≤49% at post-VPS. 15 unimproved lower (84.2 14.3% post-VPS ≤34% other 8 developed subdural fluid collection (SDFC), values 43%–75% 3 A postoperative increase noted 6 system malfunction. One patient experienced both SDCF <h3>CONCLUSIONS:</h3> decreases all whom VPS works properly, rate decrease being higher show improvement. Postoperative suggests precipitous drop may be consequence increased drainage herald SDFC.
