The advantages and potential challenges or considerations of the coaxial balloon technique.

Considerations/variables	Perceived or potential advantages	Potential challenges or other considerations
One-stage operation	- Streamlines the procedure, reducing total time spent in the interventional suite. - Potentially reduces the overall risk of complications by limiting the number of procedural steps.	- May be challenging for patients in high risk of intracranial hemorrhage, such as those with a large infarct core about 70 mL
Balloon-guiding catheter (BGC) use	- Provides proximal flow arrest, reducing the risk of distal thrombus migration during the procedure. - Enhances control over the intervention site, improving safety and efficacy. - Reduces the procedural time.	- Requires a learning curve, especially in navigating and positioning the BGC effectively. - The added device cost and the potential for complications related to BGC manipulation.
Procedure success rate	- Achieved 100% technical success in the study, indicating high efficacy in appropriate cases.	- The success rate may vary with operator experience and case complexity, particularly in cases with severe stenosis or challenging anatomy.
Procedure adaptability	- Versatile technique that can be adapted to various anatomical challenges.	- Requires tailored approaches for different anatomical variations, which may complicate the procedure.
Risk mitigation	- BGC use for proximal flow arrest provides enhanced protection against embolic complications.	- Full benefits of risk mitigation may only be realized by experienced operators.
Cost-Effectiveness	- Overall cost savings than staged operations.	- The need for specialized equipment like BGC increases initial procedure costs.
