Carotid endarterectomy reduces stroke risk in patients with>70%symptomatic stenosis.We present our results of percutaneous transluminal angioplasty (PTA)as an alternative treatment.Ninety-eight patients with symptomatic> 70%stenosis of the internal carotid artery were considered for PTA.Details of the procedure,complications,and 4-year follow-up were registered. Eighty-five PTAs were performed in a 4-year period.Transient cardiovascular effects were frequent:hypotension(54.1%),bradycardia(67. 1%),asystole(25.9%),and syncope(16.5%).Transient ischemic attack occurred in 3 of 82 patients(3.7%),and disabling stroke occurred in 4(4.9%); mortality was 0%.After a mean follow-up period of 18.7 months,4 patients died,1 due to fatal stroke.The overall probability of surviving any stroke or death was 86.7%.Restenosis(>70%)was seen in 6 cases(7.4%).PTA may be a reasonable treatment for symptomatic atherosclerotic stenosis,at least in patients at high risk for carotid endarterectomy. |
