Résumé :

We studied the nycterohemeral variations of homovanillic acid (HVA) in ventricular cerebrospinal fluid (CSF) in 24 patients undergoing monitoring of intracranial pressure as part of the normotensive hydrocephalus (NTH) work-up. CSF samples were obtained every 4 h in each patient. The mean individual values of HVA in the ventricular CSF ranged from 133 to 421 ng/ml, and they could not be correlated to any clinical feature. The intraindividual levels of HVA were stable throughout 24 hours, with a variation coefficient inferior to 10% in 63% of cases, and inferior to 20% in all the patients.
