Percutaneous Transluminal Angioplasty for Bilateral ICA Occlusive Lesions

Abstract

We performed Percutaneous Transluminal Angioplasty (PTA) in 50 patients with internal carotid artery (ICA) stenosis.

Fifteen of these patients also showed signs of contralateral ICA occlusive lesions. Various neurological symptoms, such as hemiparesis or convulsions, frequently appeared in these patients with contralateral lesions during PTA.

The balloon inflation time was restricted in 2 patients who experienced convulsions during PTA, resulting in an unsuccessful dilatation in one case. No permanent neurological deficits appeared as a result of PTA in these cases. The treatment for these cases is discussed in this report.
