Referrals for suspected ventriculo-peritoneal shunt dysfunction and necessity for further imaging.

Shunt series (SS) X-rays are often performed as additional routine initial investigations for suspected ventriculo-peritoneal shunt dysfunction, despite low diagnostic utility and radiological implications. We reviewed such referrals at our neurosurgical unit and found an 8.3% sensitivity rate for SS; consistent with current evidence. SS should not be performed routinely.
