BACKGROUND: To quantify the effectiveness and safety of the Trevo® Retriever for endovascular treatment of acute ischemic stroke (AIS) patients in China.
METHODS: Trevo Retriever Registry (China) was a prospective, multicenter, non-comparative, open-label study of patients with AIS treated with the Trevo Retriever. The primary outcome was the proportion of patients achieving an expanded Thrombolysis in Cerebral Infarction (eTICI) score ≥2b at the end of endovascular treatment. Secondary outcomes included first-pass eTICI score ≥2b and 90-day modified Rankin Scale (mRS) score ≤2.
RESULTS: The Trevo Retriever Registry (China) enrolled and followed 201 patients (62.1 ± 12.5 years-old; 70.6% male) at 11 centers. The pre-procedure NIHSS score and ASPECTS were 16 (interquartile range (IQR), 13-21) and 7 (IQR, 6-9), respectively, and 188 (93.5%) patients had an mRS score of 0 prior to the stroke. The main stroke etiology was large artery atherosclerosis, accounting for 71.6% (144/201) of patients. Post-procedure eTICI ≥2b was 98.4% (187/190). First-pass eTICI ≥2b was 74.7% (136/182). The 90-day good outcome (mRS ≤2) rate was 73.6% (148/201). The 90-day all-cause mortality was 5.5% (11/201). Neurological deterioration at 24 h post-procedure was observed in 7.7% (15/195) patients. Embolism in a new territory was seen in one patient (0.5%). Two (1.0%) procedure-related adverse events (AEs) occurred, which were intra-procedure cerebral artery embolism. No Trevo related AEs occurred.
CONCLUSIONS: This real-world study of the Trevo Retriever in China demonstrated a high rate of revascularization and first-pass success that resulted in an overall high good function outcome rate and low mortality.
