Conventional angiography showing ruptured left vertebral artery V4 segment dissecting aneurysm. A Right vertebral artery catherization with retrograde filling of the left vertebral artery and aneurysmal filling. B Left vertebral artery catherization in oblique view, showing the ruptured dissecting aneurysm (black arrow) and the left PICA arising proximal to the aneurysm (white arrow), C left vertebral artery after occlusion of the aneurysm with parent artery occlusion distal to the origin of the left PICA, coils marked by white arrow, D right vertebral artery catheterization after coiling with no retrograde filling of the aneurysm
