FIG 3. Patient 18.

A, Oblique frontal DSA of a 22-year-old man with a traumatic dissection with flow-limiting stenosis and a large pseudoaneurysm (asterisks) of the upper cervical right internal carotid artery near the skull base.

B, A 7 x 30 mm Precise stent (Cordis Corp.) was placed with reversal of the associated stenosis (lateral projection). The pseudoaneurysm associated with the dissection, aside from stent placement, was also treated by coil embolization with a reduction in its size; however, the tear in the internal carotid artery at this level was large and the pseudoaneurysm partially filled.

C, There was an interval increase in the size of the pseudoaneurysm with coil compaction at 19 days (lateral projection). The pseudoaneurysm was retreated by placement of additional coils and deployment of a second 7 x 30 mm Precise stent (Cordis Corp.) across the pseudoaneurysm neck, which resulted in near-total obliteration. The internal carotid artery flow remained normal and the true lumen fully patent and clear of thrombus.
