Introduction: Inballance in secretion and resorption of cerebrospinal fluid leads to hydrocephalus. This can appear secondary to an inflammatory process or after intracerebral hemorrhage. Monitoring the hemodynamics of cerebral bloodflow with echoDoppler we studied the evolution of posthemorrhagic hydrocephalus. Materials and methods: we followed the variations of rezistivity index (RI) in 9 infants with posthemorrhagic hydrocephalus, born in our unit between 01.01.2005 and 12. 31.2007. Results: Increase of RI was found in 7 (77,77%) cases. 4 (44,44%) babies needed ventriculo-peritoneal shunting, while the others showed no further worsening after 3-5 months, with no clinical or ultrasound signs of intracerebral hypertension. Conclusions: Doppler sonography was efficient in our cases, variations of RI being a sensible sign of hydrocephalus evolutiveness, if added to clinical findings, leading the clinician to a correct approach of therapeutical attitude.
