Duplex surveillance may detect more post-CEA stenosis than appreciated clinically; leaves open optimal management of early lesions.
What is the incidence and natural history of carotid artery stenosis following endarterectomy as detected by duplex scanning?
Duplex scanning reveals a higher incidence of postoperative carotid stenosis than clinical estimates, highlighting the transient nature of some early myointimal lesions.
