(A) The three-dimensional rotational angiography shows a wide neck aneurysm of the right SCA. (B) The angle of the right SCA/PCA was wide, and the angle of the right SCA/BA was acute. (C) An Excelsior SL-10 microcatheter (Stryker, Kalamazoo, MI, USA) was derived to the right SCA via the right PCoA and the right P1. Coils were embolized using another microcatheter delivered from the right VA. (D) After the aneurysm was embolized, a Neuroform Atlas stent 3*21 (Stryker) was derived by the Excelsior SL-10 covering the neck of the aneurysm. (E) The angiography just after the intervention shows that the Raymond-Roy occlusion classification is class IIIa. The stent was positioned from the right SCA to the right P1 just proximal to the right PCoA (arrows).. BA, basilar artery; Lt. PCA, left posterior cerebral artery; Lt. SCA, left superior cerebellar artery; Rt. ICA, right intracervical artery; Rt. PCA, right cerebral artery; Rt. P1, right P1 segment of PCA; Rt. PCoA, right posterior communicating artery; Rt. SCA, right superior cerebellar artery.

(A) The three-dimensional rotational angiography shows a wide neck aneurysm of the left SCA. The bleb was embolized in the first treatment after subarachnoid hemorrhage (arrow). (B) The angle of the left SCA/PCA was wide, and the angle of the left SCA/BA was acute. (C) An Excelsior SL-10 microcatheter was placed at the left PCoA adjacent the PCoA. Two framing coils were embolized using another microcatheter delivered from the right VA. (D) The Excelsior SL-10 microcatheter derived to the SCA. (E) A Neuroform Atlas stent 3*21 (Stryker) was placed covering the neck of the aneurysms; then finishing coils were embolized. (F) The angiography just after the intervention shows that Raymond-Roy occlusion classification is class IIIa. The stent was placed from the left SCA to the left P1 just proximal to the junction with the PCoA (arrows).. BA, basilar artery; Lt. ICA, left intracervical artery; Lt. PCoA, left posterior communicating artery; Lt. P1, left P1 segment of PCA; Lt. SCA, left superior cerebellar artery; Rt. PCA, right posterior cerebral artery; Rt.

The aneurysm had a wide neck and a bleb with a neck length of 5.09 mm, diameter of 3.71 mm, and depth of 2.98 mm (Fig. 2A). SCA-BA and SCA-P1 angles, as measured from working projections of rotational angiography with 3D image reconstruction, were 30  and 150 , respectively (Fig. 2B and Table 1). Another microcatheter was delivered to the aneurysm from the right VA along a microguidewire, and two framing coils were embolized (Fig. 2C). An Excelsior SL-10 was delivered to the left SCA (Fig. 2D), and a Neuroform Atlas stent 3*21 (Stryker) was placed from the left SCA to the left PCoA. Then, two finishing coils were embolized (Fig. 2E). The Raymond-Roy occlusion classification was class IIIa (Fig. 2F).
