BACKGROUND: Carotid angioplasty and stenting (CAS) for recurrent stenosis after carotid endarterectomy (CEA) has been proposed as an alternative to redo CEA. Although early results are encouraging, the extended durability remains unknown. We present the long-term surveillance results of CAS for post-CEA restenosis. METHODS: Between 1998 and 2004, 57 CAS procedures were performed in 55 patients (36 men) with a mean age of 70 years. The mean interval between CEA and CAS was 83 months (range, 6 to 245). Nine patients (16%) were symptomatic. RESULTS: CAS was performed successfully in all patients. No deaths or strokes occurred. A periprocedural transient ischemic attack (TIA) occurred in two patients. During a mean follow-up of 36 months (range, 12 to 72 months), two patients exhibited ipsilateral cerebral symptoms (1 TIA, 1 minor stroke). In 11 patients (19%), in-stent restenosis (> or =50%) was detected post-CAS at month 3 (n = 3), 12 (n = 3), 24 (n = 2), 36 (n = 1), 48 (n = 1), and 60 (n = 1). The cumulative rates of in-stent restenosis-free survival at 1, 2, 3, and 4 years were 93%, 85%, 82%, and 76%, respectively. Redo procedures were performed in six patients, three each received repeat angioplasty and repeat CEA with stent removal. The cumulative rates of freedom from reintervention at 1, 2, 3, and 4 years were 96%, 94%, 90%, and 84%, respectively. CONCLUSION: Carotid angioplasty and stenting for recurrent stenosis after CEA can be performed with a low incidence of periprocedural complications with durable protection from stroke. The rate of in-stent recurrent stenosis is high, however, and does not only occur early after CAS but is an ongoing process.
