Abstract
Background
Mechanical thrombectomy with stent retrievers has become a standard treatment for acute ischemic stroke due to large vessel occlusion. Here we present a multicenter US experience using the EmboTrap III stent retriever, the latest iteration within its class.
Methods
We retrospectively reviewed patients with acute ischemic stroke treated with the EmboTrap III device at 4 US centers. We recorded baseline demographics, clinical characteristics, and procedural details. Outcomes included first-pass effect (FPE), modified FPE (mFPE), final mTICI scores, 90-day functional outcomes, and complications.
Results
A total of 92 patients were included, median age of 72 years, and 56.5% were women. The mean NIHSS on admission was 16.6 ± 8.1 and the median ASPECTS score was 9. IV thrombolysis was administered in 34.1%. Median last known normal to reperfusion time was 304 min. Final successful reperfusion (mTICI ≥ 2b) was achieved in 91.3% of patients. FPE (mTICI ≥ 2c after a first pass with the device) was achieved in 53.3% of patients, and mFPE (mTICI ≥ 2b after a first pass with the device) was achieved in 79.3% of patients. At 90 days, 22.9% of patients had modified Rankin Scale (mRS) ≤ 2. There were no device-related complications.
Conclusion
In this multicenter study, the EmboTrap III achieved high final recanalization success and FPE/mFPE rates with low complication rates.
