Diagnostic brain magnetic resonance imaging and angiography. Multiple infarctions were observed in the basilar artery (A), right posterior cerebral artery (B), and right middle cerebral artery (C) territories on magnetic resonance imaging (orange arrows), (D) occlusion of the right internal carotid artery (green arrow) and basilar artery (blue arrow) were observed on magnetic resonance angiography.

The angiogram revealed a carotid stump at the right carotid, a hypoplastic left vertebral artery with V4 segment occlusion, and an acute occlusion of the V4 segment of the right vertebral artery (Figure 2).
Mechanical thrombectomy for vertebrobasilar artery occlusion. (A) Sofia Plus aspiration catheter was used to access the vertebrobasilar artery thrombosis (orange circle). (B) Angiogram revealed the complete recanalization of the vertebrobasilar artery and the occlusion of the right middle cerebral artery-M1 segment (blue arrow).

The follow-up angiogram revealed the complete recanalization of the vertebrobasilar artery, but the occlusion of the right MCA-M1 segment was observed (Figure 3).
Mechanical thrombectomy for right middle cerebral artery occlusion. (A) A CatchV35 stent retriever was fully deployed across the occluded right middle cerebral artery (blue arrows). (B) Complete recanalization of the vertebrobasilar artery (red arrows) and the right middle cerebral artery (orange arrow), assessed as thrombolysis in cerebral infarction stage III.

The follow-up angiogram revealed the complete recanalization of the vertebrobasilar artery and the right MCA, assessed as thrombolysis in cerebral infarction (TICI) stage III (Figure 4).
Brain magnetic resonance angiogram. (A) Before the intervention, the vertebrobasilar artery and right middle cerebral artery showed acute occlusion (yellow circle). (B) After the intervention, the complete recanalization of the vertebrobasilar artery (green arrow) and right middle cerebral artery (orange arrow) was observed.
