Fig 5.

A, Follow-up unsubtracted x-ray image acquired at 6 months after stent-assisted coiling of a right superior hypophyseal artery aneurysm does not show any stent struts. Arrows show proximal and distal stent markers, and the arrowhead shows the coil mass. B, Contrast-enhanced CBCT in an oblique projection (2.5-mm MIP) indicates that the stent is kinked at the inner radius of the carotid siphon (arrow). C, The cross-sectional view (1.0-mm average intensity projection) of the stent device shows that the struts are malposed to the walls of the parent artery (arrows).
