There is currently no proof of the long-term clinical effectiveness of
either carotid percutaneous transluminal angioplasty (CPTA) or stent-
assisted carotid percutaneous transluminal angioplasty (SACPTA). Never
theless, these types of endovascular therapies for carotid revasculari
zation offer several apparent advantages over surgery. Until level I e
vidence of clinical safety and efficacy is available, however, the app
lication of CPTA or SACPTA should be restricted to patients consider-e
d poor candidates for endarterectomy, or those participating in approv
ed multidisciplinary research initiatives.
