First Pass Success with NeVa M1 (4mm x 30mm)
Thrombectomy was done under distal aspiration with NeVa M1 (4mm x 30mm). Distal aspiration was used as flow control strategy.

Full recanalization (TICI 3) was possible with a single pass and significant thrombus was observed throughout the body of NeVa and inside the distal tip.
Post-op CT
Control CT showed demarcation of the core of infarct in basal ganglia
Clinical Success
Post-procedure NIHSS of the patient was 6 and she began to recover immediately.
