Figure 6.
Saccular aneurysm of a primitive trigeminal artery. Panels (A,B) show pretreatment images of a saccular aneurysm of a right-sided primitive trigeminal artery aneurysm. Panel (A) is the reconstructed and volume rendered CT-angiography. Panel (B) gives a posterior–anterior DSA projection. Panel (C) shows the nonsubtracted posttreatment control DSA image, nicely demonstrating the helical radiopaque markers of the low profile self-expandable stent and the radiopaque mass of platin microcoils, sufficiently excluding the aneurysm from the intracranial circulation. Panel (D) shows the corresponding subtracted DSA image. The formerly aneurysm-carrying vessel displays regular endoluminal contrast filling and now reveals signs of periprocedural damage.
