Early results with EmboTrap III stent retriever: A multicenter US experience

Area of Science:

• Neurology
• Interventional Neurology
• Medical Devices

Background:

• Mechanical thrombectomy is a standard treatment for acute ischemic stroke caused by large vessel occlusion.
• The EmboTrap III stent retriever represents a new iteration in endovascular therapy.

Purpose of the Study:

• To evaluate the safety and efficacy of the EmboTrap III stent retriever in a multicenter US setting.
• To assess outcomes including first-pass effect, reperfusion rates, and functional outcomes in patients treated with EmboTrap III.

Main Methods:

• Retrospective review of 92 patients with acute ischemic stroke treated with EmboTrap III across 4 US centers.
• Data collected included baseline characteristics, procedural details, and outcomes such as first-pass effect (FPE), modified FPE (mFPE), final mTICI scores, and 90-day modified Rankin Scale (mRS) scores.
• Complications related to the device were also recorded.

Main Results:

• Successful reperfusion (mTICI ≥ 2b) was achieved in 91.3% of patients.
• First-pass effect (mTICI ≥ 2c) was observed in 53.3%, and modified FPE (mTICI ≥ 2b) in 79.3% of cases.
• At 90 days, 22.9% of patients achieved a modified Rankin Scale score of ≤ 2, with no device-related complications.

Conclusions:

• The EmboTrap III stent retriever is effective in achieving high rates of final recanalization and first-pass effect in acute ischemic stroke.
• The device demonstrated a favorable safety profile with low complication rates in this multicenter experience.
• These findings support the EmboTrap III as a viable option for mechanical thrombectomy in large vessel occlusion stroke.
