(case 15) A ruptured VADA was reconstructed with one Enterprise (black arrow) and one Solitaire (white arrow) stent assisted coiling, and immediate total obliteration was achieved at a local hospital (A, B, C). After 7 months, a recurrence was observed at the proximal region of VADA and was effectively retreated with an additional LVIS stent (arrowhead) without coiling at our hospital (D, E). A 5-month follow-up angiogram showed normalization (F).

Clinical data of all the patients.

(case 3) Left VA angiography detected a VADA with a long configuration and tortuous parent artery (A). Modified stent-assisted semi-jailing was first manipulated with a 4.5×37 mm Enterprise stent (black arrow). An additional LVIS stent (white arrow) was then deployed (B, C). Immediate post treatment angiography (D) and 7-month follow-up (E, F) demonstrated progressive vessel remodeling and aneurysm occlusion.

(case 22) The left vertebral angiography at admission showed a PICA-involved VADA, with the PICA arising from the lesion (A). We performed double overlapping LVIS stents (black arrow and white arrow) and loose coiling packing. The immediate angiographic result was partial occlusion of the VADA with the patency of involved PICA (B, C). This patient suffered from mild vertigo and hoarseness after treatment and MR imaging revealed two tiny punctate foci of diffusion restriction in the lower pon(D, E). The angiographic follow-up at 8 months showed progressive aneurysm occlusion without compromise of PICA (F).
