Purpose:
This study aimed to evaluate the efectiveness and safety of the NeVa stent retriever as fIrst- and second-line device for mechanical thrombectomy in acute ischemic stroke.
Methods:
In this retrospective single-center study, all consecutive patients that underwent mechanical thrombectomy with NeVa stent retriever as first- or second-line device due to intracranial vessel occlusion with acute ischemic stroke between March and November 2022 were included.
Results:
Thirty-nine patients (m=18, f=21) with a mean age of 69.9 ± 13.3 years were treated with the NeVa stent retriever. NeVa stent retriever was used as first-line device in 24 (61.5%) of patients and as second-line device in 15 patients (38.5%).
First-pass rate (≥mTICI 2c) of NeVa stent retriever was both 66.7% when used as first- or second-line device.
Final recanalization rate including rescue strategies was 92.3% for ≥mTICI2c and 94.9% for ≥mTICI2b. No device-related minor or major adverse events were observed.
A hemorrhage was detected in 33.3% of patients at 24h post-thrombectomy dual-energy CT, of which none was classifed as symptomatic intracerebral hemorrhage.
NIHSS and mRS improved signifcantly at discharge compared to admission (p<0.05).
Conclusion:
The NeVa stent retriever has a high effectivity and good safety profile as first- and second-line device for mechanical thrombectomy in acute ischemic stroke.
