Summary
The Embotrap 3 stent-retriever demonstrated a high rate of first pass effect and successful recanalization in a real-world patient cohort. This indicates its effectiveness in mechanical thrombectomy for stroke treatment.
Area of Science:
- Neurology
- Interventional Neurology
- Medical Devices
Background:
- Mechanical thrombectomy is a crucial treatment for acute ischemic stroke.
- Stent-retrievers are key devices used in mechanical thrombectomy.
- Evaluating the real-world performance of new devices is essential.
Purpose of the Study:
- To assess the efficacy and outcomes of the Embotrap 3 stent-retriever in a real-world setting.
- To determine the rate of first pass effect (FPE) and final recanalization.
- To analyze patient demographics, clot characteristics, and functional outcomes.
Main Methods:
- Retrospective review of a prospectively maintained database.
- Inclusion of patients treated with Embotrap 3 stent-retriever between January 2021 and January 2022.
- Recording of baseline data, procedural outcomes (eTICI scores), and 90-day modified Rankin Scale (mRS) scores.
Main Results:
- 110 patients were included, with a median NIHSS of 18.
- First pass effect (FPE) was observed in 41.8% of cases; modified FPE in 59.1%.
- 43.8% of patients achieved a modified Rankin Scale (mRS) score of ≤2 at 90 days.
Conclusions:
- The Embotrap 3 stent-retriever shows a high rate of FPE in clinical practice.
- The device achieves a high rate of final recanalization.
- Real-world data supports the effectiveness of Embotrap 3 in mechanical thrombectomy.
