Aim. Comparison of restenosis in patients who underwent both carotid artery angioplasty with stenting (CAS) and contralateral carotid endarterectomy (CEA).
Methods. From our CAS data registry (1998-present) all patients with a history of contralateral CEA at any other time were selected (n = 63). Mean age was 70.6, SD=6.8 for CAS and 68.2, SD=6.1 for CEA and symptomatic carotid artery stenosis was present in 24% of patients pre-CAS and 40% pre-CEA. All CEAs were primary interventions, 19% of CAS were secondary to restenosis after previous ipsilateral CEA. All patients were followed up prospectively with duplex at 1 year (CAS: n=58, CEA: n=59), 2 years (CAS: n=44, CEA: n=53), 3 years (CAS: n=27, CEA: n=41), and every year thereafter. Within each patient we compared restenosis (>50%) between CAS and CEA procedures.
Results. After a follow-up of 28.7 months for CAS (SD=16.9) and 54.4 months for CEA (SD=39.5) the rate of ≥ 50% restenosis for CAS vs CEA at 1, 2, and 3 years was 23% vs 10%; 31% vs 19%; and 34 vs 24%, respectively (log rank P=NS).
Conclusion. Our intrapatient comparison of patients who underwent both CAS and contralateral CEA did not reveal significant difference in restenosis between both procedures.
