N. Aihara et al., BREAKAGE OF SHUNT DEVICES (SOPHY PROGRAMMABLE PRESSURE VALVE) FOLLOWING IMPLANTATION IN THE HYPOCHONDRIAC REGION, Child's nervous system, 13(11-12), 1997, pp. 636-638
We report on three cases in which shunt devices (Sophy programmable pr
essure valve) broke while implanted in the hypochondriac region. None
of these patients had an apparent history of trauma related to the shu
nt valve. The outlet connector was broken at the same site in each cas
e. The dissociation between the movement of the thorax and that of the
abdomen may have caused the formation of a crack in the outlet connec
tor.
