The Paragon balloon guide catheter (BGC) improves mechanical thrombectomy (MT) for large vessel occlusion (LVO) by enabling more distal tip placement, leading to a higher first pass effect (FPE). This enhances procedural efficiency in stroke treatment.
Area of Science:
- Neurology
- Interventional Neuroradiology
- Medical Devices
Background:
- Large vessel occlusion (LVO) stroke requires timely mechanical thrombectomy (MT).
- Balloon guide catheters (BGCs) are crucial for MT, aiding in flow arrest and device delivery.
- Optimizing BGC use can improve MT procedural efficiency and outcomes.
Purpose of the Study:
- To evaluate the efficacy of the Paragon balloon guide catheter (BGC) in mechanical thrombectomy (MT) for large vessel occlusion (LVO).
- To compare procedural outcomes between the Paragon BGC and other BGCs in LVO patients.
- To identify predictors of first pass effect (FPE) in MT.
Main Methods:
- Retrospective review of MT procedures for LVO between October 2023 and September 2025.
- Comparison of patients treated with Paragon BGC (n=41) versus other BGCs (n=83).
- Propensity score matching (PSM) and multivariable analyses to assess outcomes and predictors of FPE.
Main Results:
- The Paragon BGC group showed significantly higher rates of distal BGC tip placement (53.7% vs. 8.4%) and FPE (58.5% vs. 48.2%).
- Lower aspiration catheter delivery failure rates were observed with the Paragon BGC (14.6% vs. 26.5%).
- PSM analysis confirmed higher distal tip placement and FPE rates with the Paragon BGC (59.5% vs. 48.6%).
Conclusions:
- The Paragon BGC is associated with improved procedural efficiency in MT for LVO.
- Distal BGC tip placement and the use of Paragon BGC are independent predictors of achieving FPE.
- The Paragon BGC facilitates more effective MT for LVO, potentially improving patient outcomes.
