Endoscope-assisted microneurosurgery for intracranial aneurysms

Area of Science:

• Neurosurgery
• Minimally Invasive Surgery
• Cerebrovascular Surgery

Background:

• Endovascular techniques have advanced intracranial aneurysm treatment.
• Surgery remains crucial for complex, broad-based aneurysms.
• Combined endoscopic and microsurgical techniques (EAM) may enhance surgical results.

Purpose of the Study:

• To evaluate the advantages and limitations of EAM for intracranial aneurysms.
• To assess the impact of various factors on EAM efficacy.

Main Methods:

• Retrospective analysis of 173 patients with 206 aneurysms treated with EAM (2002-2012).
• Standard skull base approaches were utilized.
• Endoscope use involved initial inspection, operative time, and final inspection.

Main Results:

• No surgical mortality was associated with EAM.
• Complications directly related to endoscopic procedures were infrequent.
• Postoperative cerebral angiography confirmed successful clipping.

Conclusions:

• EAM efficacy is minimally affected by preoperative condition, surgical timing, or hydrocephalus.
• Lesion's anatomical location and size are primary determinants of EAM success.
• Dedicated equipment and adequate surgical training are crucial for optimal EAM outcomes.
