Endoscopic assistance in intracranial aneurysm surgery enhances visualization of critical structures, potentially reducing surgical risks and improving patient outcomes. This technique aids in dissecting aneurysms and performing clipping procedures with greater precision.

Area of Science:

  • Neurosurgery
  • Minimally Invasive Techniques
  • Cerebrovascular Surgery

Background:

  • Intracranial aneurysms pose significant risks, necessitating advanced surgical approaches.
  • Traditional aneurysm surgery can involve extensive retraction of neural structures, increasing morbidity.
  • Endoscopic technology offers potential for improved visualization in complex neurosurgical procedures.

Purpose of the Study:

  • To evaluate the utility and safety of endoscopically assisted treatment for intracranial aneurysms.
  • To assess the impact of endoscopic visualization on surgical dissection and clipping procedures.
  • To determine the effect of this technique on operative complications and patient outcomes.

Main Methods:

  • Retrospective analysis of 66 patients undergoing endoscopically assisted intracranial aneurysm treatment over three years.

  • Categorization of aneurysms by size (including giant aneurysms) and location (posterior circulation).
  • Detailed recording of endoscope utilization for anatomical assessment, aneurysm sac dissection, and clipping.

    • Main Results:

    • Endoscopic assistance was employed for visualization in 16 patients and dissection in 43.
    • Clipping was performed exclusively under endoscopic observation in seven cases.
    • A single intraoperative rupture occurred during basilar tip aneurysm preparation; postoperative complications included temporary neurological impairment and one hemiparesis.

    Conclusions:

    • Endoscopic assistance significantly improves visualization of intracranial aneurysms and surrounding anatomy.
    • This enhanced visualization facilitates minimally invasive dissection and clipping, reducing the need for neural retraction.
    • Endoscopic techniques in aneurysm surgery are associated with reduced morbidity and improved surgical safety.
