Fig 2.

Lateral digital subtraction angiography, left VA injection, performed prior to endovascular treatment (A). A fusiform aneurysm affecting the middle of the BA is shown (solid arrow). Angiography, AP projection, left VA injection, performed on day 7 after coiling (B), shows tapering of the proximal BA leading to a short segment of occlusion (long arrow) between the AICA and SCA origins. Some collateral vessels are seen arising from the PICAs and AICAs.

Angiography performed 4 months after coiling (C) shows persistent occlusion of both the BA and the aneurysm.
