title: Contrast examination of cerebrospinal fluid shunt malfunction in infancy and childhood.
abstract: The technique of contrast examination of the common types of cerebrospinal fluid (CSF) shunts is described. The findings in 250 shuntograms are analysed and the results discussed. The most common cause of shunt malfunction was shunt blockage. Errors of interpretation occurred in 16 shuntograms and were more frequent in Pudenz systems than in Spitz-Holter. The technique is simple, safe, accurate and does not require special apparatus. There was only one serious complication in 250 shuntograms. It is particularly useful when the anterior fontanelle has closed.
