Complications Following Ventriculo-Atrial Shunts in Hydrocephalus

Surgical treatment of posterior fossa tumors in infancy and childhood: techniques and results

In a collective of 72 children with tumors of the posterior fossa, the preoperative diagnosis, operation planning and performance, and use of additional procedures, like the preliminary ventricular drainage and interventriculostomy are described. The extent of intra- and postoperative complications is given. Postoperative lethality was 0% in the group operated on between 1979 and 1991. The responsible factors are discussed. The findings support the opinion of ALBRIGHT (1989) that the prognosis for such patients is most promising in the hands of a specialist in pediatric neurosurgery.

Valve invagination in ventriculoatrial shunting

✓ The authors present eight cases of an unusual mechanical complication of ventriculoatrial shunts that has not been reported previously. In these eight patients, the metal parts of the valve slipped into the silicone casing. Although the cause is not completely clear, there are simple ways of preventing this from happening.
