Endovascular treatment in patients with carotid artery dissection and intracranial occlusion: a systematic review

Abstract

Purpose

Recently, multiple randomised controlled trials showed efficacy of endovascular treatment over traditional care in patients with acute ischemic stroke due to an intracranial anterior circulation occlusion. Internal carotid artery (ICA) dissection with a concomitant intracranial occlusion is a rare but important cause of severe acute ischemic stroke. Although this subtype of acute ischemic stroke is mostly treated with endovascular treatment, treatment outcomes are still sparsely studied. This study assesses the clinical outcome and reperfusion rates by means of a systematic review.

Methods

Electronic databases of PubMed, EMBASE and Web of Science were searched up to October 1, 2016 for articles describing endovascular treatment in patients with intracranial artery occlusion and ICA dissection.

Results

Sixteen studies were included in the analysis. Most studies showed favourable outcome and successful reperfusion. However, most included studies had a high risk of bias.

Conclusion

In the reviewed studies, endovascular treatment in patients with ICA dissection and concomitant proximal intracranial occlusion was associated with favourable outcome. This could point in the direction of endovascular treatment being a beneficial treatment method for these patients. However, this review has only taken data of a limited group of patients into account. A pooled analysis of patients from recently published endovascular treatment trials and running registries is therefore recommended.
