Background Carotid endarterectomy (CEA) and carotid artery stenting (CAS) reduce the risk of stroke in patients with severe carotid stenosis. The aim was to compare contemporary treatment trends and outcomes after CEA and CAS between states of Australia. Methods A retrospective analysis was conducted on data from the Australasian Vascular Audit between 2010 and 2017. The primary endpoint was perioperative stroke or death (S/D). We also analysed stroke and death independently and revascularization rates per 100 000 population. Results A total of 15 413 patients underwent carotid revascularization (CEA 14 070; CAS 1343). S/D rates were similar for CEA and CAS (1.9% versus 1.8%; P = 0.37; symptomatic 2.1% versus 2.3%; P = 0.12; asymptomatic 1.5% versus 1.1%; P = 0.67). Patients ≥80 years (2.7% versus 1.7%; P = 0.01), those who had shunts (2.2% versus 1.7%; P = 0.03) or surgery in teaching hospitals (2.6% versus 1.4%; P = 0.02) had higher rates of S/D after CEA. Patients whose proceduralist used a cerebral protection device had lower S/D rates after CAS for symptomatic disease (4.8% versus 2.2%; P = 0.03). There was a wide variation in practice between states, where CAS as a proportion of total carotid procedures ranged from 0% to 17%, and a wide variation in outcomes, with rates of S/D varying between 1.4–6.6% for CEA and 0–6.7% after CAS. Conclusion Outcomes after CAS are equivalent to CEA when performed by vascular surgeons, however significant variation exists for both choice of revascularization procedure and perioperative outcomes between states. Further investigation is needed to determine whether clinical care pathways should be revised to achieve consistency and quality of outcomes. |
