[Balloon-Assisted Coil Embolization for Cerebral Aneurysms].

Area of Science:

• Neurosurgery
• Interventional Radiology
• Biomedical Engineering

Background:

• Balloon-assisted coil embolization is a prevalent technique for treating cerebral aneurysms.
• It offers advantages over alternative methods like stent-assisted coiling and flow diverters.
• Selecting the correct balloon catheter is crucial for successful treatment outcomes.

Purpose of the Study:

• To provide a comprehensive review of available balloon catheters for cerebral aneurysm treatment.
• To elucidate the structural and property distinctions among various balloon catheter devices.
• To guide the selection of appropriate balloon catheters based on aneurysm characteristics and procedural needs.

Main Methods:

• Classification of balloon catheters based on lumen number (single vs. double) and balloon compliance.
• Analysis of differences in priming, usage, and mechanical properties between single and double lumen devices.
• Evaluation of how balloon compliance impacts suitability for different aneurysm morphologies.

Main Results:

• Balloon catheters are primarily categorized by lumen configuration and balloon compliance.
• Single and double lumen devices exhibit distinct procedural requirements and mechanical behaviors.
• Balloon compliance is a critical factor influencing device selection for specific aneurysm shapes.

Conclusions:

• Understanding balloon catheter characteristics is essential for optimizing cerebral aneurysm embolization.
• Key differentiating factors include lumen number and balloon compliance, impacting device selection and performance.
• This review provides a framework for informed decision-making in choosing the appropriate balloon catheter for neurovascular interventions.
