FIG 2. Patient 19.
A, Lateral DSA of a 19-year-old man with a traumatic pseudoaneurysm arising from the left internal carotid artery at the level of the mid-C2 vertebral body. There was a long segment of dissection flap (arrows) from the pseudoaneurysm (asterisk) to the level of the cavernous internal carotid artery.
B, Road-mapping guidance was used to select the true lumen with a 0.018-inch Roadrunner guidewire (Cook Inc.). A 9 x 30 mm Precise stent (Cordis Corp.) was placed across the neck of the pseudoaneurysm (asterisk), which resulted in slower flow within the pseudoaneurysm (lateral projection).
C, Follow-up angiography at 6.2 months showed normal caliber at the site of injury with healing of the pseudoaneurysm and dissection flap (lateral projection).
