Primary and secondary outcomes evaluationData are No. (%). P < 0.05 was considered statistically significantStatistical analysis showed that complications were comparable between the groups. Overall, general adverse events occurred in 9/58 patients (15.5%) in the Numen group and 11/66 patients (16.7%) in the Axium group, with a common odds ratio of 0.680 (95% CI, 0.351–2.402, P = 0.862). Most of these events were symptoms, such as vomiting, headache, fever, or allergic response. In addition, there were 4 cases of intraoperative ischemic stroke (1 in the Numen group and 3 in the Axium group), which were considered after further examination by MRI and angiography. Among these 4 cases, the case of stroke in the Numen group and one in the Axium group were thought to be caused by parent artery occlusion; the other 2 cases were caused by intrastent thrombosis. All ischemic stroke patients recovered well after medical therapy and rehabilitation.
