Migration is a rare complication of venticuloperitoneal shunts and is thought to be associated with the "memory" of the plastic tubing and the windlass effect of neck flexion and extension. The purpose of this case report is to detail a very rare case of complete distal to proximal shunt migration.
Significant proximal shunt migration is an extremely rare complication that has only been reported in the literature on six occasions [1–5], with the full migration of the distal and proximal aspects of the shunt catheter into a subgaleal pocket reported only twice [2, 4]. The proposed mechanism for the migration of the catheter involves the "windlass" effect combined with the retained "memory" of the shunt tubing . The flexion and extension of the child's neck in the days following the surgery combined with the "memory" of the plastic tubing were the likely culprits causing the shunt migration.
