Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Technology

Background:

  • Microsurgical clipping remains a primary treatment for intracranial aneurysms.
  • Accurate visualization of aneurysm neck anatomy and perforating vessels is crucial for successful clipping.
  • Limitations of traditional microscopy can hinder optimal surgical outcomes.

Observation:

  • A prospective study evaluated the endoscope as an adjunct in microsurgical treatment for 79 intracranial aneurysms across 55 patients.
  • The endoscope was utilized for pre-clipping, intra-clipping, and post-clipping assessments.
  • Key applications included observing neck anatomy, perforators, and verifying clip placement.

Findings:

  • The endoscope provided superior visualization of anatomical features in 26 aneurysms and exclusive information in 15 cases.

  • It facilitated clip repositioning in 7 cases due to residual neck or neurovascular compression.
  • Endoscope use reduced the need for intraoperative angiography in many patients, especially when combined with micro-Doppler probes.

    • Implications:

    • Endoscope-assisted microsurgery represents a significant advancement in treating intracranial aneurysms.
    • Enhanced visualization improves surgical precision, potentially leading to better patient outcomes.
    • This technique may reduce operative time and the necessity for certain diagnostic procedures.
