About

To compare safety and effectiveness of NeVa Stent Retriever (SR) to Control SR in the treatment of stroke caused by large vessel occlusion. The main questions it aims to answer are:

How do recanalization rates for NeVa SR compare with those of the Control SR? How does NeVa SR safety compare with Control SR safety?

Full description

NITRO is a multicenter, retrospective, comparative, non-inferiority, cohort study designed to compare NeVa SR with Control SR for safety and effectiveness when removing thrombus in subjects presenting with acute ischemic stroke (AIS) due to large vessel occlusion (LVO). The objective of the NeVa International, Multi-center, Retrospective Comparative stent retriever (SR) study (NITRO) study is to compare safety and effectiveness of the NeVa SR to commonly used SR with CE-mark, and US FDA clearance, to restore blood flow in patients experiencing acute ischemic stroke due to large intracranial vessel occlusion. NITRO aims to collect data describing real-world clinical practices when using SRs according to their indicated use within the indicated population. As such, the eligibility criteria define patients who are diagnosed with AIS and are indicated for endovascular MT aligning to the target population for the proposed device. The present study will include data from subjects treated with either NeVa SR or one of the Control SR. Control SR will include any SR commonly used in thrombectomy trials as first-line strategies and which represent CE-mark, and US FDA cleared stent retrievers.
