AB  - In three male patients with long-standing Silastic ventriculoperitoneal shunts, a sleeve of dystrophic calcification surrounding the catheter at the thoracic inlet developed, visible on plain radiographs. Such calcification indicates degeneration and tethering of the shunt catheter. It was associated with shunt disconnection in two patients.
