Answer

Endovascular therapies are more likely to be used if there is significant vertebrobasilar disease as the cause of PCA stroke or if the patient fails to respond to medical management. When the ICA is the source of stroke via a fetal PCA variant, surgical endarterectomy or endovascular stenting of the ICA may be appropriate.

More recently, treatments such as vertebral artery stenting have been used and may replace the medical-treatment-only approach to intrinsic vertebral artery disease.
