Figures & Tables

FIGURE 1.

Intracranial digital subtraction angiography images in lateral view (A AND B) showing the right primitive trigeminal artery (arrowhead) and an incidental saccular aneurysm on its lateral wall (arrow). The aneurysm is further detailed in the three-dimensional (3D) reconstruction (B). The lateral wall aneurysm has a wide neck, with largest diameters approximately 2.12 and 2.03 mm (C AND D).

FIGURE 2.

Intracranial digital subtraction angiography images in lateral view (A AND B) demonstrating the deployment of the Pipeline Vantage flow diverter stent (4×12 mm) within the primitive trigeminal artery (arrow). Immediate postoperative angiography confirms proper stent placement (B). Follow-up angiograms in anteroposterior (C) and lateral (D) views of the internal carotid artery show no evidence of distal embolization.

FIGURE 3.

Cone-beam computed tomography images in lateral view (A AND B) demonstrating the correct positioning of the flow diverter stent within the persistent trigeminal artery (arrow). Preoperative three-dimensional (3D) angiographic reconstruction illustrating a lateral wall aneurysm of the persistent trigeminal artery (C). Six-month postoperative 3D angiography confirming successful aneurysm occlusion (D).
