Insights

Ventriculoperitoneal shunts can cause torticollis in children due to material aging and mechanical stress. This case report details a 14-year-old boy whose torticollis resolved after removing the aged shunt.

Area of Science:

  • Neurosurgery
  • Biomedical Engineering
  • Pediatric Neurology

Background:

  • Ventriculoperitoneal (VP) shunts are crucial for managing hydrocephalus, particularly in children.
  • Aging of shunt materials and mechanical forces can lead to complications.
  • Torticollis is a rare but significant complication associated with VP shunts.

Observation:

  • A 14-year-old male presented with torticollis as a late complication 12 years post-VP shunt placement for aqueductal stenosis.
  • The patient had a left-sided VP shunt.
  • Physical examination revealed tethering of the shunt tube and a surrounding fibrocalcified band.

Findings:

  • The study discusses the pathophysiological mechanisms of VP shunt material aging and mechanical stress leading to torticollis.
  • Biomechanical dysfunction of the shunt material caused tethering at the neck, a highly mobile area in a growing child.
  • Surgical removal of the shunt tube and fibrocalcified band resulted in complete resolution of the torticollis.

Implications:

  • This is the first reported case of torticollis as a complication of VP shunt material aging and mechanical traction.
  • Highlights the importance of considering shunt biomechanics in pediatric patients with neurological conditions.
  • Suggests potential for novel interventions or material improvements to prevent such late-onset complications.

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...

Mitral Valve Prolapse III: Nursing Management

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Mitral Valve Prolapse II: Assessment and Management

IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular tachycardia.

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
