Delayed stenosis following stentriever use in acute stroke intervention.

ABSTRACT

We report two cases of delayed post-embolectomy stenosis--that is, a new stenosis in the vascular bed of a previous endovascular embolectomy. The first case was discovered incidentally in a patient returning after embolectomy for evaluation of cerebral aneurysms. The second case was discovered on an MR angiogram obtained to screen for stenosis. This was prompted by our experience with the first case. To our knowledge, this phenomenon has not been reported previously.
