Summary
We studied Pourcelot’s index of resistance (RI), which shows cerebral vascular resistance, in the anterior cerebral artery (RI — ACA), and in the basilar artery (RI — BA), and the RI ratio (= RI — ACA/RI — BA) in 13 measurements of hydrocephalus. (1) The mean RI — ACA, RI — BA and RI ratios before treatment were significantly higher than those found after treatment and in normal infants. (2) Before treatment, all RI ratios had increased to 1.00 and more. After treatment and in normal infants, however, all RI ratios had decreased less to than 1.00. We consider that the RI ratio is useful for evaluating the need for or the effect of treatment in hydrocephalus.
