Additive Effects of Intra-arterial Tenecteplase for Successful Thrombectomy Due to Acute Basilar Artery Occlusion

Summary

Recent studies revealed the safety and effectiveness of EVT in patients with acute occlusion at basilar artery, showing that up to 46% of patients receiving EVT had favorable functional outcome at 3 months (ATTENTION and BAOCHE trials, ESOC). Although the rate of successful recanalization can be as high as 90% , a large number of these patients remains to be functionally independent while recovery. In addition, a number of recent studies indicated the functional outcome of patients with successful recanalization of TICI 2b was not as good as those with TICI 3 grade. Therefore, restoring reperfusion of distal vessels and territorial microcirculation may be pivotal to further improvement of neurological outcomes for AIS patients receiving EVT. Correspondingly, a very recent Spanish multicenter randomized trial showed the effect of further functional improvement of post-EVT intra-arterial alteplase for successful mechanical thrombectomy in anterior circulation More importantly, head-to-head comparison between TNK and tPA showed the former has a significantly higher chance of reperfusion, indicating that TNK may be a potentially better candidate for post-EVT bridging.

Based on the above findings, we hypothesize in the present study that, adjunct intra-arterial tenecteplase after successful thrombectomy could enhance the functional improvement in patients with acute basilar artery occlusion.
