Dystrophic calcification of the soft tissues surrounding the cardioperitoneal catheter is a rare cause of dysfunction of the shunt system. This pathological process can lead to fixation of the distal catheter to the surrounding tissues or to disconnection of the shunt system. The degradation of a silicone shunt system was first reported in 1983. And in 1988, a case of calcification of the distal catheter of the shunt system was first described.
Description of the observation: The patient is 24 years old, he entered the neurosurgical department with complaints of headache, dizziness, nausea, unsteadiness when walking. He suffers from hydrocephalus since childhood, repeatedly carried out liquor shunting operations, including revisions of shunts (the last - in 2010). CT of the brain: strained internal hydrocephalus, thickened hyperdivision areas of cardioperitoneal catheters in the cervical and upper thoracic regions, their fragmentation in the abdominal cavity. Locally: in the cervical and upper thoracic region, the distal catheters of the shunt systems are thickened and fixed to the surrounding tissues. Considering the above, it was decided to remove fragments of the distal catheters and reinstall the peritoneal catheter. Intraoperative: the distal LSh catheters broke down while trying to remove, therefore it was decided not to remove them. A new cardioperitoneal catheter was implanted elsewhere from a non-distant LS, implanted into the abdominal cavity. In satisfactory condition, the patient was discharged from the hospital.
The follow-up period is over 2 years, the patient´s condition is satisfactory, there are no complaints. There is no neurological loss.
