Angioplasty of Acute Occluded Cerebral Arteries

Abstract

22 cases of stenosed or occluded cerebral arteries were treated by percutaneous transluminal angioplasty (PTA) in acute stage. There were 10 internal carotid lesions, 4 middle cerebral artery lesions, 5 intracranial vertebral artery lesions, and 3 basilar artery lesions. 14 cases were treated for residual stenosis after recanalization using urokinase.

Successful dilatation (over 50%) was achieved in 16 cases (73%). 3 lesions were inaccessible due to atherosclerotic change. There were no major complications. Restenosis was observed in 4 internal carotid lesions and 1 middle cerebral lesion. 7 (50%) cases with internal carotid lesions and 5 (63%) cases with vertebrobasilar lesions returned to their previous life.

The results suggest that PTA in acute stage is feasible for occlusive disease of cerebral arteries.
