Endovascular treatment with angioplasty or stenting versus endarterectomy in patients with carotid artery stenosis in the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS): long term follow-up of a randomised trial Lancet Neurol 2009; 8: 871-873

Published: 1st January 2009

Authors: Ederle J, Bonati LH, Dobson J, Featherstone RL, Gaines PA, Beard JD et al et al.

Conclusion

Some 504 procedures were included initially and followed for a median of five years. Up to 30 days, stroke and death rates were similar. Nor were any of the differences statistically significant after 30 days, although there were more ipsilateral strokes in the angioplasty group (11 vs. 8.6 per cent) and more ipsilateral strokes or TIA (19.3 vs. 17.2 per cent).
