Résumé : |
The aetiology and extension of peri-intraventricular haemorrhage (PIVH) are thought to be related to cerebral blood-flow alterations, and especially to increased cerebral blood-flow and fluctuating velocity of blood-flow. Using transcutaneous Doppler technique, the authors investigated cerebral blood-flow in 60 infants with gestations of less than 34 weeks. Pulsatility index (PI) and area under the velocity curve (AUVC) of the anterior cerebral arteries (ACA) were used as qualitative measures of cerebral blood-flow, and the coefficient of variation of PI and AUVC as indicators of fluctuations in blood-flow velocity. A reasonable correlation was found between PI and AUVC and their coefficients of variation in the ACA. First onset of PIVH was related to fluctuating blood-flow velocity, and extension of PIVH with both increased velocity (indicating increased blood-flow) and fluctuating velocity. Increased cerebral blood-flow and its fluctuating pattern were positively correlated with arterial carbon dioxide tension. |
