Figure 6.

Digital subtraction angiography (DSA) image (a) of a 63-year-old male patient with basilar artery stroke showing basilar artery dissection (arrow) as a cause of stroke and partial recanalization of the basilar artery after the first pass of the thrombectomy stent. The DSA image (b) in the same patient showing extension of the dissection to the left vertebral artery after repeated interventional manoeuvres. A Wallstent^® (Boston Scientific, Natick, MA) was placed to compress the dissection flap and restore flow to the vertebral artery; however, the patient died because of extensive brain stem infarction.
