Postoperative CT scans after ventricular punctures revealed high-density areas (intracerebral hemorrhage) in 13.2% and low-density areas in 59.3% of patients. Factors like age and puncture site influenced these findings.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Neurology

Context:

  • Ventricular punctures are common neurosurgical procedures.
  • Continuous ventricular drainage (CVD) and shunts are frequently performed.
  • CT scans are essential for postoperative assessment.

Purpose:

  • To analyze CT scan findings after ventricular punctures.
  • To identify factors influencing postoperative high-density areas (HDA) and low-density areas (LDA).
  • To correlate imaging findings with clinical manifestations.

Summary:

  • 755 ventricular punctures were analyzed in 450 patients.
  • Postoperative CT revealed HDA in 13.2% and LDA in 59.3%.
  • Factors influencing HDA included old age, occipital puncture, and previous brain damage; LDA factors included young age, occipital puncture, and new tracts.

Impact:

  • HDA correlated with acute neurological deficits like altered consciousness and epilepsy.
  • LDA showed gradual improvement, with some cases resolving within a year.
  • Understanding these factors can optimize neurosurgical procedures and patient outcomes.
