A multimodal treatment of basilar artery re-occlusion - case report.

BACKGROUND

Stroke due to basilar artery occlusion (BAO) is a severe neurovascular condition with only recently proven effectiveness of mechanical thrombectomy as treatment. Early re-occlusion of the basilar artery (RE-BAO) is an even more challenging form of stroke to treat, associated with poor outcomes and still no optimal treatment guidelines. There are only a few reported cases covering this topic thus far.

CASE PRESENTATION

We present a 52-year-old male patient with RE-BAO treated with a combination of bridging intravenous (IV) tissue plasminogen activator (tPA), mechanical thrombectomy (MT), rescue intraarterial (IA) tPA, and after re-occlusion, repeated bridging IV tPA and repeated MT in a 75-hour time span.

DISCUSSION

In previous trials applying IA tPA after MT showed promising results in patients with anterior circulation stroke. However, our case report implies that using a combined treatment of IV tPA before and IA tPA after MT in posterior circulation shows similar results.

CONCLUSION

To our knowledge, this is the first case of RE-BAO managed with the aforementioned multimodal treatment. Such an approach recently showed promising results in the anterior circulation, and our report supports the effectiveness of multimodal recanalization treatment in the posterior circulation as well.
