A 70-year-old man with severe stenosis in the left internal carotid artery (the white arrow) coexisted with an ipsilateral unruptured posterior communicating aneurysm (the black arrow), measuring 5 mm (A). A single-stage endovascular procedure was implemented. After stent placement of the left internal carotid artery, stent-assisted embolization of the ipsilateral tandem aneurysm was applied. After single-stage treatment, left common carotid artery and internal carotid artery angiograms showed complete aneurysm exclusion (B) and satisfactory carotid revascularization (C).

A 70-year-old man with a history of left-sided carotid transient ischemic attacks was found to have a 90% stenosis in the left internal carotid artery coexisted with an ipsilateral unruptured posterior communicating artery aneurysm, measuring 5 mm on angiography (Figure 2).

A 75-year-old man with severe stenosis in the left vertebral artery origin (the white arrow) coexisted with an ipsilateral unruptured vertebral aneurysm (black arrow), measuring 5.5 mm (A,B). A single-stage endovascular procedure was implemented. After stent-assisted embolization of the ipsilateral tandem aneurysm, stent placement of left vertebral artery origin was applied. After single-stage treatment, the left subclavian artery angiogram showed complete aneurysm exclusion (C) and satisfactory vertebral revascularization (D).

A 75-year-old man with episodes of recurrent drop attacks and orthostatic dizziness was found to have an 80% stenosis in the starting segment of the left vertebral artery coexisted with an ipsilateral unruptured vertebral aneurysm, measuring 5.5 mm on angiography (Figure 3).

A 72-year-old man with a 6.4-mm posterior communicating aneurysm on the left internal carotid artery (the black arrow) accompanied by an 80% stenosis (the white arrow) proximal to the aneurysm (A). A single-stage endovascular procedure was implemented. The stent-assisted embolization of the aneurysm was performed, and the stent was placed to cover both the neck of the aneurysm and the stenotic segment. After the operation, the left carotid artery angiogram showed complete aneurysm exclusion and satisfactory carotid revascularization (B).
