The use of a (non-) balloon guide catheter in endovascular stroke treatment, a registry of real-life use and nationwide questionnaire.

INTRODUCTION

Despite literature suggesting benefits of a balloon guide catheter (BGC) in stroke thrombectomy, BGCs are not routinely used. This study aimed to get insights in the use of a BGC and the reasons (not) to inflate the balloon.

METHODS

Data were used of the Maastricht Stroke Quality Registry (MaSQ-Registry), a prospective registry for quality purposes of stroke patients treated between September 2020-February 2023. Additionally, a Dutch nationwide questionnaire was sent among all stroke treating physicians of the Dutch Society of Interventional Radiology (NVIR). Information on the use and reasons for selecting a (non-)BGC and using the BGC was collected.

RESULTS

Out of 511 patients registered in the MaSQ-Registry, 458 were included. In 69% (n=317) of the patients a BGC was used; in 68% (n=214) the balloon was not inflated. In 95% of the posterior circulation occlusions a non-BGC was used. In total 47 treating physicians from sixteen stroke centers responded to the questionnaire. 51% (n=24) preferred a non-BGC and 30% (n=14) never used a BGC. 52% and 18% of the BGC-users estimated they inflate the balloon in 80-100% and 0-20% of the times, respectively. The main reasons reported for not inflating the balloon were when the BGC was occlusive (47%) or not placeable (34%) in the carotid artery.

CONCLUSION

This study shows variation in the use of (non-)BGC use with and without inflated balloon among treating physicians in the Netherlands, highlighting current limited consensus regarding the use of (non-)BGCs among stroke treating physicians.
