[Spinal catheter-associated cerebrospinal fluid leak].

Cerebrospinal fluid leak, with its typical postdural puncture headache, occurs in 8-25 % of patients after insertion of a spinal catheter for treatment with an intrathecal pain pump. Symptoms are usually self-limiting; only rarely is an epidural blood patch used. In this case of a 49-year-old woman, we assumed a postdural puncture headache after replacement of the spinal catheter. Because of the persistence of symptoms and serous wound secretion around the paravertebral incision, we decided to test the catheter under radiological control with a contrast agent. Leakage could be seen within the spinal catheter, which was responsible for the symptoms. Because of an ongoing infection accompanied by meningitis the whole system had to be removed.
