Acta Neurochirurgica – JULY 2025Background:
Various different technologies have been developed to optimise the mechanical thrombectomy procedure and first pass recanalisation. We report our initial experience with the NeVa NET – a novel stent-retriever with built in distal microfiltration net.
Methods:
Vesalio performed a retrospective review of our prospectively maintained databases to identify all patients treated with the NeVa NET 4 × 30 mm device. We recorded the baseline demographics, NIHSS, ASPECT score and clot characteristics, first pass and final eTICI scores, complications and 90-day mRS.
Results:
We identified 20 patients:
- Gender: 50% male
- Average age: 67.9 ± 16.2 yrs
- Median NIHSS 18 (range: 6–29)
- 30% received tPA
- Average clot length: 21.6 ± 8.9 mm
- Median ASPECT score: 9 (range 5–10)
- In 18 cases the NeVa NET could be tracked into position, in 2 cases it could not be tracked into position within the 0,021inch microcatheter
Recanalization Rates:
First pass eTICI ≥ 2c
(n = 17)
94%
Final eTICI ≥ 2c
(n = 17)
94%
The average number of
NeVa NET passes:
1
Emboli to new territories:
0
- No cases of vessel rupture or dissections occurred due to the NeVa NET
- 50% of patients achieved mRS 0–2
- SAH was seen in 31.3% and SICH in 6.3% of the 16 patients for whom a 24 h CT head was available
Conclusion:
The NeVa NET stent-retriever is uniquely designed to prevent distal embolisation and our initial experience demonstrates a very high FPE and mFPE. We believe this is the first publication on the use of this novel technology and larger studies are warranted.
