Area of Science:

  • Neurosurgery
  • Pediatric Neurology
  • Spinal Cord Disorders

Background:

  • Hydromyelia, a condition involving fluid-filled cavities within the spinal cord, presents diverse etiologies and clinical manifestations.
  • Management strategies for hydromyelia are often tailored to the specific underlying cause, such as Chiari malformations, myelomeningoceles, or tethered cords.

Purpose of the Study:

  • To review the surgical management experience with 22 patients diagnosed with hydromyelia.
  • To evaluate the effectiveness of different surgical interventions based on preoperative and intraoperative neurodiagnostic findings.

Main Methods:

  • Preoperative magnetic resonance imaging (MRI) and intraoperative ultrasound were utilized for diagnosis and surgical planning.
  • Surgical interventions included hindbrain decompression, myelotomy with cyst drainage, stenting, obex plugging, cyst-pleural shunting, and modified terminal ventriculostomy, depending on the specific condition.

Main Results:

  • The study included patients with Chiari malformations, myelomeningoceles, tethered cords, and post-arachnoiditis cavitation.
  • Common presentations included progressive scoliosis, pain, and Lhermitte's phenomenon, with classical symptoms like brachial amyotrophy being less frequent.
  • Patients with tethered cords were often asymptomatic regarding their spinal cord cavities.

Conclusions:

  • Tailored surgical approaches guided by advanced imaging (MRI and ultrasound) are crucial for managing hydromyelia.
  • The specific etiology of hydromyelia significantly influences the choice of surgical intervention and patient outcomes.
  • Intraoperative ultrasound is valuable for precise surgical decision-making, particularly in cases involving the obex.
