Insights

Lumboperitoneal shunts for hydrocephalus can cause lower limb neurologic deficits and spinal deformities due to arachnoiditis. This study reviewed 375 children, finding significant rates of these complications.

Area of Science:

  • Neurosurgery
  • Pediatric Neurology
  • Spinal Surgery

Background:

  • Lumboperitoneal (LP) shunts are used to treat communicating hydrocephalus.
  • Potential complications include neurologic deficits and spinal deformities, often attributed to arachnoiditis.

Purpose of the Study:

  • To investigate the incidence of shunt-induced neurologic deficits and spinal deformities in children who underwent LP shunts.
  • To analyze the types and prevalence of these complications.

Main Methods:

  • Retrospective chart review of 375 pediatric patients who received LP shunts between 1960 and 1981.
  • Data collection focused on documented neurologic deficits and spinal deformities.

Main Results:

  • 63 out of 375 patients (16.8%) showed evidence of shunt-induced neurologic deficits.
  • Common deficits included back pain (34 patients), hamstring tightness (45 patients), and foot deformities (40 patients).
  • Spinal deformities such as lumbar hyperlordosis, lordoscoliosis, and scoliosis were observed in 49 patients.

Conclusions:

  • LP shunts in children may lead to significant neurologic and spinal complications.
  • Arachnoiditis involving the conus medullaris and lower lumbar roots is the suspected cause of these deformities.
