Long-term results after ventriculo-atrial shunting in children

A consecutive series of 120 patients with infantile hydrocephalus who were submitted to ventriculo-atrial shunting was studied. The average follow-up was 11 years. There was no operative mortality; 7 patients died during the follow-up period, but only in 1 case was the cause of death a consequence of the shunt procedure. The incidence rates of infection and slit ventricle syndrome were 4.2% and 1.8%, respectively. Shunt revision was performed on 253 occasions yielding a revision rate of 2.2 per patient. Of these 253 revisions 167 (66%) took the form of elective lengthening of the atrial catheter. The number of reoperations to adjust the length of the atrial catheter or to revise the distal end of the shunting system is a major disadvantage, which actually favors ventriculo-peritoneal shunting as the primary procedure for the treatment of pediatric hydrocephalus
