Abstract:
The use of CT angiography is described in three patients for the evaluation of intracranial clips after surgery for an aneurysm. A postprocessing technique is described in which shaded-surface-display models were superimposed on maximum intensity projection CT angiograms. CT angiograms showed residual aneurysmal filling adjacent to a clip, patency of a vessel thought to be compromised by recent clip placement, and errant position of a clip, which required repeat surgery.
