Pitfalls in aneurysm surgery in acute stages

Area of Science:

• Neurosurgery
• Vascular Surgery
• Microsurgery

Background:

• Complex aneurysms pose significant surgical challenges due to factors like size, location, and involvement of critical vessels.
• Existing neurosurgical approaches may lack clarity in managing acute-stage complex aneurysms.
• A review of 1,433 cases identified four primary pitfalls in aneurysm surgery.

Purpose of the Study:

• To enumerate and review four critical aspects of aneurysm surgery pitfalls.
• To elaborate on a specific conceptual and microsurgical technical approach for dissecting and clipping complex aneurysms.
• To present strategies for safe and definitive treatment of challenging intracranial aneurysms.

Main Methods:

• Minimal brain retraction and reduction of intracranial tension via ventricular tap or hematoma evacuation.
• Establishment of a venous pathway for blood circulation.
• Sharp dissection utilizing a novel jet irrigation bipolar suction method, tentative clipping, and dome coagulation.

Main Results:

• The described microsurgical techniques, including minimal retraction and specialized dissection/clipping methods, were applied to 1,433 cases.
• The approach aims to prevent ischemic changes and shorten operative time.
• Successful and definitive treatment was achieved in the vast majority of patients.

Conclusions:

• The presented conceptual and microsurgical strategies provide effective solutions for common pitfalls in complex aneurysm surgery.
• This approach allows for safe and definitive treatment of challenging intracranial aneurysms.
• The principles discussed offer options to overcome significant obstacles in aneurysm surgery.
