Second asymptomatic carotid surgery trial (ACST-2): a randomised comparison of carotid artery stenting versus carotid endarterectomy. Lancet 2021; 398: 1065-1073.

Published: 9th December 2021

Authors: Halliday A, Bulbia R, Bonati LH, Chester J, Cradduck-Bamford A, Peto R et al.

Conclusion

A total of 3625 patients were included and followed for five years. Perioperative stroke and death rates were similarly low with both methods. The rate of disabling or fatal non procedure-related stroke within five years was 2.5 per cent in both groups.
