Article Figures & Data
Figures
- Fig 1.
Lateral DSA image shows an aneurysm originating from the supraclinoid portion of the internal carotid artery at the level of the posterior communicating artery. Vessel narrowing due to vasospasm is visualized in the supraclinoid segment of the left internal carotid.
- Fig 2.
Immediate postembolization lateral DSA image demonstrates complete occlusion of the aneurysm.
- Fig 3.
Twelve-month follow-up angiogram, lateral image, demonstrates complete occlusion of the aneurysm with the presence of a thin radiolucent band separating the coil mass from the arterial lumen (arrow). This finding corresponds to a white-collar neck.
- Fig 4.
Lateral DSA image shows two supraclinoid internal carotid artery aneurysms, the larger originating from the ventral wall proximal to the posterior communicating artery and immediately opposite the ophthalmic artery, and a second smaller aneurysm arising at the junction of the right internal carotid artery and the ophthalmic artery.
- Fig 5.
Immediate postembolization lateral DSA image demonstrates complete occlusion of the aneurysm.
- Fig 6.
Six-and-a-half month follow-up angiogram, lateral image, demonstrates complete occlusion of the aneurysm with the presence of a radiolucent band separating the coil mass from the arterial lumen. This finding corresponds to a white-collar neck. Note the contraction of the coil mass, with reduction of its size when compared with the immediate postembolization angiogram.
