- Fig 1.
MR images obtained in a 19-month-old female patient who presented with three episodes of decreased movement and weakness of the left arm and leg.
A, Axial T1-weighted image, obtained through the level of the midpons when the patient was 4 months old.
B, Contrast-enhanced T1-weighted image, obtained through the same level when the patient was 19 months old. A large aneurysm has developed, projecting off of the basilar artery to the right.
- Fig 2.
Volume-rendered MR angiogram of the intracranial arterial circulation shows the large aneurysm of the basilar artery. Arrow, fetal origin posterior cerebral artery on right; arrowheads, acute angulation of basilar artery as it traverses aneurysm.
- Fig 3.
Nineteen GDCs were deployed into the aneurysm through a right-sided microcatheter, and three more GDCs were deployed at the distal junction of the aneurysm lumen and the basilar artery through a left-sided system.
A, Digital subtraction angiogram of the left vertebral artery in the anteroposterior projection shows partial filling of the aneurysm with GDCs.
B, Repeat injection in the same projection after occlusion shows opacification of all proximal basilar artery branches and no distal flow.
C, Digital subtraction angiogram of the left internal carotid artery shows collateral flow to the basilar tip via the small left posterior communicating artery (arrowheads).
- Fig 4.
MR images obtained 3 days after the procedure.
A, Axial T2-weighted image, obtained through the same level as the image shown in Figure 1, shows small foci of hyperintensity in the cerebellum (arrows) and hypointensity from the platinum coils filling the aneurysm.
B, Lateral volume-rendered MR angiogram shows the flow to the basilar tip (arrowheads) via the left posterior communicating artery (arrow), as well as flow into the proximal basilar artery from the vertebral arteries.
