Retractorless surgery for intracranial aneurysms

Area of Science:

• Neurosurgery
• Cerebrovascular Surgery

Background:

• Microsurgical clipping of intracranial aneurysms necessitates deep brain access via the subarachnoid space.
• Conventional fixed retractors used for surgical corridor maintenance are associated with documented brain injuries.

Purpose of the Study:

• To introduce dynamic retraction strategies as an alternative to fixed retractors in aneurysm surgery.
• To evaluate the efficacy of dynamic retraction in preventing brain injury and ensuring surgical success.

Main Methods:

• Implementation of dynamic retraction techniques, eliminating constant pressure from fixed retractors.
• Integration of optimal patient positioning and neuroprotective anesthetic protocols.
• Assessment of surgical corridor adequacy and aneurysm visualization.

Main Results:

• Dynamic retraction successfully provided adequate visualization of intracranial aneurysms.
• Excellent surgical outcomes were achieved without the use of fixed retractors.
• The proposed strategy mitigates the risk of brain injury associated with traditional retraction methods.

Conclusions:

• Dynamic retraction is a viable and effective alternative to fixed retractors for microsurgical aneurysm clipping.
• Combining dynamic retraction with optimized patient positioning and neuroprotection enhances surgical safety and efficacy.
• This approach offers a promising strategy for reducing iatrogenic brain injury in deep brain access surgeries.
