Hydroceles were noted in six patients who had ventriculoperitoneal shunts at less than 1 year of age. These took a few days to several months to develop. The incidence was 7% in girls and 23% in boys less than 1 year of age. Hydrocephalus was especially severe in the older patients in the group. In one case, the hydroceles cleared spontaneously when a peritoneal catheter was removed. A patent processus vaginalis may allow development of a hydrocele in the face of increased intra-abdominal fluid and pressure. The catheter position may be important, and it is possible that CSF alters the absorbing properties of the peritoneum and also prevents closure of the processus vaginalis.
在6例1岁以内接受脑室腹腔分流术的患儿中发现了鞘膜积液。这些积液在数天至数月内逐渐形成。1岁以内女童的发病率为7%，男童为23%。该组年龄较大的患儿脑积水尤为严重。有1例在拔除腹腔导管后鞘膜积液自行消退。在腹腔内液体和压力增加的情况下，未闭的鞘状突可能导致鞘膜积液的形成。导管位置可能很重要，脑脊液可能改变腹膜的吸收特性，并阻止鞘状突闭合。
