[How to Avoid Intraoperative Rupture and What to Do When It Ruptures]

Area of Science:

• Neurosurgery
• Interventional Radiology
• Anesthesiology

Background:

• Intracranial aneurysm rupture during coil embolization is a significant cause of mortality.
• Systemic heparinization is frequently used during the procedure, complicating management of rupture.
• Understanding intraoperative rupture mechanisms is key to improving patient outcomes.

Purpose of the Study:

• To address clinical questions regarding anesthesia, heparinization, and management of intraoperative intracranial aneurysm rupture.
• To provide guidance on the initial response to aneurysmal rupture during coil embolization.
• To reduce the mortality rate associated with this complication.

Main Methods:

• Review of clinical questions pertaining to anesthesia and anticoagulation in intracranial aneurysm coil embolization.
• Discussion of intraoperative aneurysmal rupture scenarios and management strategies.
• Emphasis on the balloon-assisted technique and immediate response protocols.

Main Results:

• Intraoperative aneurysm rupture is a critical complication requiring specific management.
• Immediate actions include blood pressure reduction, heparin reversal with protamine, and balloon occlusion.
• Avoiding microcatheter or coil removal during rupture is crucial.

Conclusions:

• Effective management of intraoperative intracranial aneurysm rupture can significantly decrease mortality.
• Adherence to specific protocols for rupture management is essential for patient safety.
• This guidance aims to assist clinicians in daily care during coil embolization procedures.
