[Balloon and Conventional Guide Catheters]

Area of Science:

• Neurology
• Interventional Neuroradiology
• Vascular Surgery

Background:

• Balloon guide catheters (BGC) are frequently employed in anterior circulation thrombectomy for acute ischemic stroke (AIS).
• Evidence supporting BGC utility in AIS treatment requires further clarification.
• BGCs serve dual roles: preventing distal embolization and acting as an anchor for device navigation.

Purpose of the Study:

• To review the evidence supporting the use of balloon and conventional guide catheters in treating AIS.
• To describe the characteristics of both BGCs and conventional guide catheters.
• To provide guidelines for selecting the optimal guide catheter for AIS intervention.

Main Methods:

• Literature review of studies evaluating balloon and conventional guide catheters in AIS treatment.
• Analysis of BGC characteristics, including emboli prevention and device anchoring capabilities.
• Comparison of BGCs with conventional guide catheters, considering factors like posterior circulation occlusion and transradial access.

Main Results:

• BGCs are primarily used to prevent embolization into new territories during AIS thrombectomy.
• BGCs facilitate device navigation and delivery by acting as an anchoring system.
• Conventional catheters are often preferred for posterior circulation occlusions or transradial approaches.

Conclusions:

• The selection of a guide catheter (balloon or conventional) in AIS treatment depends on specific clinical scenarios.
• Understanding the distinct advantages of each catheter type is crucial for optimizing patient outcomes.
• Further research may refine guidelines for guide catheter selection in diverse AIS presentations.
