[Shunt dysfunction secondary to peritoneal catheter migration to the scrotum].

INTRODUCTION: Valvular dysfunction secondary to obstruction of proximal catheter is relatively frequent at emergency room. However non-infectius obstruction of distal catheter is exceptional. CASE REPORT: A 6-year-old boy with dysfunction shunt due to migration of the abdominal catheter into the right scrotum. The patient was operated urgently for peritoneum-vaginal processus closure. DISCUSSION: Permeability of the peritoneum-vaginal processus (until 60% of boys younger than one year) causes hydrocele in patients with ventricle-peritoneal shunt. However migration of the peritoneal cateter is very infrequent specially in patients older than one year. In the case of this event with increased intracraneal pressure levels and shunt malfunction, emergency closure of the duct should be a priority.
