Risk factors for postoperative ventriculoperitoneal shunt requirement in pediatric patients with brain tumors

Insights

Postoperative ventriculoperitoneal shunt (VPS) placement after pediatric brain tumor resection is linked to specific risk factors. Medulloblastoma, ventricle tumors, and postoperative hematoma/hygroma increase the likelihood of needing a VPS.

Area of Science:

  • Pediatric neurosurgery
  • Neuro-oncology
  • Neurosurgical complications

Background:

  • Hydrocephalus frequently complicates pediatric brain tumors and can persist after surgical resection.
  • Ventriculoperitoneal shunt (VPS) placement is a common intervention for persistent hydrocephalus.
  • Identifying risk factors for VPS placement is crucial for optimizing patient management.

Purpose of the Study:

  • To investigate perioperative risk factors associated with the need for postoperative ventriculoperitoneal shunt (VPS) placement in children with brain tumors.
  • To identify specific tumor characteristics and post-surgical complications that predict VPS requirement.

Main Methods:

  • Retrospective study of 265 children (0-18 years) with tumors near CSF pathways undergoing resection (Oct 2015-Sep 2021).
  • Outcome assessed: VPS placement within 6 months of tumor resection.
  • Analysis included demographic, imaging, clinical variables, and adjuvant therapies.

Main Results:

  • 14.34% of patients required VPS post-resection; 49.81% had preoperative hydrocephalus.
  • Independent risk factors for VPS included medulloblastoma (OR 4.15), lateral/third ventricle tumors (OR 4.07), postoperative intraventricular hematoma (OR 3.36), and non-operated area subdural hygroma (OR 2.78).

Conclusions:

  • Tumor location (lateral/third ventricle), histology (medulloblastoma), and postoperative complications (intraventricular hematoma, subdural hygroma) are significant predictors of needing a VPS after brain tumor resection.
  • These factors aid in anticipating and managing hydrocephalus in pediatric neuro-oncology patients.

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

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...

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...

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...
