OBJECTIVE: Ventriculoperitoneal shunt is the most common cerebrospinal fluid diversion procedure to treat hydrocephalus. With the change of physiologic cerebrospinal fluid absorption site from arachnoid granulations to the peritoneum, beta 2 transferrin enters the systemic circulation. Therefore, the detection of beta 2 transferrin in the blood can possibly be used as a noninvasive method to assess the functional status of the shunt. The objective of this study was to study the presence of beta 2 transferrin in patients with functional shunts and in shunts suspected of being malfunctional.
