ABSTRACT: Cerebrospinal fistulas and pseudomeningoceles can occur after lumbar spinal surgery, and are sometimes refractory to direct repair, external drainage, and blood patches. The authors report a technique for cerebrospinal fluid (CSF) diversion from the lumbar spine to the peritoneum to assist with the management of these difficult situations. Using video-laparoscopic assistance, two shunts are placed from the lumbar region into the peritoneal cavity: first, a lumbar subarachnoid space to peritoneum shunt; and second, a meningocele cavity to peritoneum shunt. Patients are ambulated immediately after the procedure. External drains are not used. Four patients with refractory CSF leaks were successfully managed with this technique. Complications associated with prolonged bedrest and external drains were avoided. Ancillary procedures were minimized, and hospital stay was shortened. Laparoscopic assistance offered verification of accurate placement of the peritoneal catheter and shortened operative times. Dual lumbar peritoneal shunts (intrathecal-peritoneal and meningocele cavity-peritoneal), placed with laparoscopic assistance, proved effective in the management of four patients with postoperative lumbar CSF leaks, who had failed to respond to conventional treatment.Surgical Neurology 07/2003; 59(6):473-77; discussion 477-8.

ABSTRACT: Lumboperitoneal (LP) shunting has the advantage of completely extracranial surgical management, minimizing intracranial complications. An LP shunt has been intentionally adopted for patients who require cerebrospinal fluid diversion. A retrospective study was designed to examine the indications for and complications associated with LP shunts in 207 patients (including 28 pediatric patients) treated during the past 11 years. Follow-up averaging 5.1 years revealed no deaths related directly to LP shunt placement. Twenty-nine patients (14%) underwent revision of the shunt because of obstruction. Shunt-related infections were observed in only 2 patients (1%). Radicular pain occurred in 10 patients (5%), 2 of whom required shunt replacement. Postoperative occurrence of dyspnea and disturbance of consciousness necessitated conversion to a ventriculoperitoneal (VP) shunt in 2 patients (1%), who subsequently were noted to have Chiari malformations. In 4 patients (2%), an acute subdural hematoma developed after mild head trauma. Symptomatic chronic subdural hematomas were observed in 2 patients (1%). One patient had a mild myelopathy that rapidly resolved after shunt replacement. The comparison to 120 patients treated with a VP shunt during the identical period (an average follow-up of 5.2 years) suggests the following conclusions. After subarachnoid hemorrhage caused by a ruptured aneurysm, hydrocephalus is usually of the communicating type and is an indication for an LP shunt. The incidence of infection and malfunction with an LP shunt is significantly lower than that with a VP shunt. An LP shunt is also indicated for pediatric patients, although a relatively higher incidence of malfunction is noted compared to adults.(ABSTRACT TRUNCATED AT 250 WORDS)Neurosurgery 07/1990; 26(6):998-1003; discussion 1003-4. · 3.03 Impact Factor
