Percutaneous transluminal angioplasty (PTA) and stent placement are effective in patients with stenosis of the cavernous or petrous portion of the internal carotid artery (ICA), but the long-term outcomes remain unclear. The present study evaluated long-term outcomes in 54 patients treated by PTA or stent placement for stenotic lesions involving more than 50% of the cavernous or petrous portion of the ICA with ischemic symptoms or without ischemic symptoms if cerebral blood flow on single photon emission computed tomography images was decreased by 20% compared with the contralateral side. Follow-up magnetic resonance, three-dimensional computed tomography, and conventional angiography were performed. Patient condition in the follow-up period was investigated using telephone interviews or questionnaires. PTA was used to treat 13 lesions and stent placement for 41 lesions. Permanent and transient complications occurred in 2 and 5 patients, respectively. The morbidity rate was 13% (7 of 54 patients). The follow-up period ranged from 3 to 80 months (mean 29.9 months), and restenosis and occlusion were recognized in 4 patients (7.4%). Five patients died (2 of malignancy and 3 of myocardial infarction) during the follow-up period. PTA and stent placement are safe and effective in patients with stenosis of the cavernous or petrous portion of the ICA, and result in low long-term rates of restenosis.<br>
