Abstract
A persistent primitive trigeminal artery (PPTA) is a vessel remnant of carotid-vertebrobasilar
anastomosis. The aneurysm at the bifurcation of the internal carotid artery (ICA)
and PPTA tends to have a broad neck with the branch incorporated into the sac. Because
PPTA supplies to the posterior circulation and branches off direct pontine perforators,
PPTA preservation should always be considered when treating PPTA aneurysms to avoid
ischemic complications.We report a case of the wide-neck ICA–PPTA aneurysm successfully
treated with the PulseRider-assisted coil embolization, resulting in complete occlusion
with PPTA patency. Relevant anatomy and endovascular strategy of the PPTA aneurysms
are discussed.
