Ventriculo-peritoneal shunts in children reveal the natural history of closure of the processus vaginalis

摘要: Abstract Purpose: Little information is known about the natural history of closure processus vaginalis. The authors studied children who had ventriculoperitoneal shunts to determine vaginalis and better understand role intraabdominal pressure in etiology congenital inguinal hernia. Materials Methods: A retrospective review all undergoing insertion between 1985 1995 at Royal Children's Hospital was undertaken. In each case, sex, cause hydrocephalus, age shunt, subsequent development an hernia or hydrocele recorded. Results: There were 430 study. An developed 15% after a additional 6% boys. Inguinal hernias bilateral 47% boys 27% girls. incidence closely related being 30% during last 8 weeks gestation first few months life, then falling quite sharply reach 10% 1 year. Conclusions: high occurrence hydroceles shunt supports raised these conditions. It appears that associated with increased clinical hernias, but not patency inserton can be used as indirect marker time shunt. From this, we propose remains patent least which rate fall off sharply.
