Article Figures & Data
Figures
- fig 1.
56-year-old woman with SAH.
A, Preoperative MIP image from a CTA study shows an anterior communicating artery aneurysm (arrow).
B, Postoperative CTA shows clipping of the aneurysm and narrowing of the anterior cerebral artery (arrows), consistent with vasospasm.
C, DSA, anteroposterior view, confirms vasospasm involving the A1 segment of the anterior cerebral artery (arrows).
- fig 2.
51-year-old woman with SAH.
A, Preoperative CTA, anteroposterior view, shows a left MCA aneurysm (arrow).
B, Postoperative CTA shows the clipped aneurysm and narrowing of the first segments of the left ipsilateral anterior (curved arrow) and middle cerebral (straight arrow) arteries.
C, DSA, anteroposterior view, verifies vasospasm of the left anterior and middle cerebral arteries ipsilateral to the aneurysmal rupture (arrows).
- fig 3.
28-year-old man with an aneurysmal SAH.
A, Preoperative CTA, MIP image, reveals a posterior communicating artery aneurysm (arrow).
B, Postoperative CTA shows severe basilar artery spasm (open arrow) and carotid artery occlusion (solid arrow).
C, DSA, lateral view, confirms basilar artery vasospasm (arrow).
D, DSA, lateral oblique view, verifies supraclinoid ICA occlusion (arrow).
