70%. Final eTICI 2b was 95% (median 1 pass, range 1-7). There no major complications from the procedure. The rate of SAH was low (10%). Conclusion The Neurovasc Envi is a novel stent-retriever with a good safety record and excellent rates of recanalisation including high rates of FPE.

with the first pass in 213 (54.9%) participants. The total number of passes for the target lesion was 1.9 (SD 1.3). After the first pass, a modified treatment in cerebral ischemia grade (mTICI) of 2b to 3 (mTICI 2b-3) was observed in 251 (71.1%) participants and mTICI of 2c to 3 (mTICI 2c-3) was observed in 184 (52.1%). At the final angiogram, mTICI 2b-3 was observed in 380 (97.9%) participants and mTICI 2c-3 was observed in 287 (74.0%). Results varied with clot composition, but no significant difference was detected between the clot composition subgroups for mTICI 2b-3 after the first pass (P = .55). Conclusions Clot removed during neuroendovascular procedures can differ in consistency and removability, leading to an increased focus on thrombus composition as a crucial variable for improving outcomes of ischemic stroke. In this study, good final revascularization (mTICI 2b-3 at the final angiogram) occurred after aspiration thrombectomy regardless of clot composition. Ongoing analysis of collected specimens is expected to provide valuable information regarding thrombus biology and etiology and to aid in diagnosis, prognosis, and drug development.
