Long term durability and clinical outcome of a prospective randomized trial comparing carotid endarterectomy with ACUSEAL polytetrafluoroethylene patching versus pericardial patching.

AbuRahma Z, Williams E, Lee A, Jordan MD, Veith C, Dargy N et al.

J Vasc Surg 2023; 77: 1694-1699.

Two hundred procedures were included in this study. After a median follow-up of 80 months, there was no difference in the rate of freedom from stroke: ACUSEAL 93 per cent, pericardial patch 92 per cent. Whilst rates of freedom from > 80 per cent recurrent stenosis were similar, more patients with the ACUSEAL developed stenosis > 50 per cent,  P=0.49.

Comment: Whilst no clinical differences were reported, this may be enough to dissuade vascular surgeons from using the PTFE patch.
