Cerebral hemodynamic monitoring combined with infusion test in hydrocephalus.

Introduction: Disturbance in cerebrospinal fluid (CSF) circulation may overlap with abnormality of cerebral blood flow (CBF) in hydrocephalus. Transcranial Doppler (TCD) ultrasonography is a non-invasive technique able to assess CBF velocity (CBFv) dynamics in response to a controlled rise in ICP during CSF infusion tests.

Research Question: Which TCD-derived cerebral hemodynamic parameters change during controlled rise of ICP, and in which direction?

Material And Methods: Infusion tests combined with TCD monitoring and non-invasive monitoring of arterial blood pressure (ABP) were conducted in 65 hydrocephalic patients.
