Figure 5: Distal radial “snuff box” approach for low-profile visualized intraluminal support stent assisted coiling of a 1.2 cm ruptured left superior cerebellar artery aneurysm. (a) A 25-cm 6F sheath was placed, and roadmap of the distal brachial (white star), proximal ulnar and radial arteries (white arrow) is seen. (b): (Anteroposterior view unsubtracted) the 6F Benchmark guide can be seen in the right V3 portion of the vertebral artery (white arrows). (c) (Anteroposterior view) Right vertebral run demonstrates a large 1.2-cm basilar/superior cerebellar artery aneurysm (white star) with fusiform superior cerebellar artery originating from the aneurysm inferiorly (white arrow). (Patient and family wishes were for endovascular treatment after discussion of open vascular treatment and endovascular treatment). (d) (Anteroposterior view) Right vertebral roadmap is revealing the Headway 17 (white star) in the left posterior cerebral artery and the Headway Duo in the superior cerebellar artery aneurysm (white arrow). (e) (Anteroposterior view) Post-low-profile visualized intraluminal support stent coiling right vertebral injection reveals the dome of the aneurysm has been excluded, a small amount of filling of the superior cerebellar artery is present inferiorly (white arrow), which will be observed for now
