Angiograms illustrate stent-assisted coil placement in a persistent TA aneurysm.

A, Lateral view shows the stent bridging the aneurysm prior to deployment (arrows). The guidewire for the stent delivery system has been introduced into the angular artery. The stiff guidewire causes visible kinking of the ICA.

B, The stent is fully deployed (solid arrows), and the first detached coil, placed through the stent struts, is visible. The lower part of the coil helix covers the origin of the persistent TA (open arrow).

C, After additional coils are inserted, the first coil is pushed back into the aneurysm dome, opening the origin of the persistent TA (open arrow). The stent supports the coil mass. The small end of the coil is trapped between the vessel wall and the aneurysm (solid arrow).
