Initial Experience with NeVa Stent Retriever in the United Arab Emirates

Objectives: We present the initial experience with a novel stent retriever to treat acute large-vessel occlusions, particularly paying attention to the rate of first-pass affect. We analyze some of the technical aspects of the NeVa device that might increase the first-pass effect incidence. Methods: Patients treated in Cleveland Clinic Abu Dhabi since June 2019 are included. We present the clinical and radiological data of these patients. In addition, the pathological study of the retrieved clots is included. Results: A total of seven patients were treated with the NeVa device. In six patients, a combination of aspiration and stent retriever was initially used. All of them had first-pass recanalization. Two were occluded at the internal carotid terminus; one of these was a tandem occlusion. Three had the occlusion at the M1 level. One of these required the placement of an intracranial stent due to the suspicion of underlying intracranial atherosclerosis. Another one had an M2 occlusion. Finally, a patient who was initially treated with only aspiration had a residual M2 clot that was retrieved in a single attempt with the NeVA device. In cases where the clot was retrievable, it was sent to pathology for analysis. Conclusion: In our experience thus far, the NeVA device has proven to be safe and effective in the management of large-vessel occlusion clot retrieval.
