BACKGROUND: Spinal catheter insertion in lumboperitoneal shunt (LPS) surgery for normal pressure hydrocephalus (NPH) can result in radiculopathy due to mechanical irritation of the nerve roots of the cauda equina. Here, we analyzed the position of LPS shunts placed without portable fluoroscopy in 72 patients, a subset of whom developed postoperative radiculopathy.
METHODS: We retrospectively analyzed how frequently 72 consecutive NPH patients experienced radiculopathy following LPS catheter placement performed without intraoperative fluoroscopy.
RESULTS: The rate of incorrect catheter placement was 15.3% (11/72 cases). We observed that is, downward placement in 6.9% (5/72 cases), hyperflexion in 6.9% (5/72 cases), and subcutaneous migration in 1.4% (1/72 cases) patients. One patient with initial correct LPS placement developed radicular pain 5-day postoperatively attributed to 1-cm of catheter movement; they recovered simply by utilizing oral analgesics for 1-month duration.
CONCLUSION: LPS insertion without fluoroscopic guidance resulted in a 15.3% risk of spinal catheter displacement. We suggest, therefore, that intraoperative imaging guidance be utilized for the placement of LPS in patients with NPH and/or for other pathology to avoid the 15.3% risk of postoperative radiculopathy.
