PURPOSE: The initial and long-term results of angioplasty and primary stenting for the treatment of occlusive lesions involving the supra-aortic trunks were studied. METHODS: All patients in whom angioplasty and stenting of the supra-aortic trunks was attempted were included in a prospective registry. Results are, therefore, reported on an intent-to-treat basis. The preprocedural and postprocedural clinical records, arteriograms, and noninvasive vascular laboratory examinations of 83 patients (41 men [49.4%] and 42 women [50.6%]; mean age at intervention, 63 years) in whom endovascular repair of the subclavian (66, 75.9%), left common carotid (14, 16.1%), and innominate (7, 8.0%) arteries was attempted were retrospectively reviewed. RESULTS: Initial technical success was achieved in 82 of 87 procedures (94.3%). The inability to cross 4 complete subclavian occlusions and the iatrogenic dissection of 1 common carotid artery lesion accounted for the 5 initial failures. Complications occurred in 17.8% of 73 subclavian and innominate procedures, including access-site bleeding in 6 and distal embolization in 2. Ischemic strokes occurred in 2 of 14 common carotid interventions (14.3%), both of which were performed in conjunction with ipsilateral carotid bifurcation endarterectomy. The 30-day mortality rate was 4.8% for the entire group. By means of life-table analysis, 84% of the subclavian and innominate interventions, including initial failures, remain patent by objective means at 35 months. No patients have required reintervention or surgical conversion for recurrence of symptoms. Of the 11 patients available for follow-up study who underwent common carotid interventions, 10 remain stroke-free at a mean of 14.3 months. CONCLUSION: Angioplasty and primary stenting of the subclavian and innominate arteries can be performed with relative safety and expectations of satisfactory midterm success. Endovascular repair of common carotid artery lesions can be performed with a high degree of technical success, but should be approached with caution when performed in conjunction with ipsilateral bifurcation endarterectomy.
