Figure Legends
Figure1.
Preoperative brain MRI showed a scant subarachnoid hemorrhage on T1-weighted image (A) and T2-weighted image (B). CTA revealed a dissected MCA aneurysm (arrow), which was misdiagnosed as saccular aneurysm (C, D).
Figure 2.
Intraoperative views showed the dissecting aneurysm in the left MCA.
A: Dissected MCA aneurysm without blood flow, and a small branch (arrow) with scant blood flow.
B: TCD applied to the distal segment (arrow) of the dissecting MCA; there is no blood flow.
C: The photo shows a 9mm dissected MCA aneurysm with atherosclerotic change
D: Dissected aneurysm was wrapped, and clip reinforcement was done.
Figure 3.
Postoperative brain CT (A, B) showed no newly developed acute cerebral infarctions.
Figure 4.
Postoperative left carotid angiogram on day 14, arterial phase, anteroposterior view, showing wrapping evidence and total occlusion of dissected segment (A), The lateral view (B) and the oblique view (C) show the same findings.
