The only randomized study to date, the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS
) comparing carotid angioplasty and CEA demonstrated a stroke rate of 10% and 9.9% respectively17.
Estos porcentajes son similares con los reportados en otros estudios que oscilan entre el 2 y 5%, CAVATAS
reporto un 14%.
On the basis of these earlier and other more recent studies (CAVATAS
Investigators, 2001; Executive Committee for the Asymptomatic Carotid Atherosclerosis Study, 1995), agreement has been reached to support the benefit of carotid revascularization (regaining the carotid artery patency by removing the plaque surgically or by applying angioplasty-stenting endovascularly) over medical management for symptomatic patients with documented ipsilateral carotid stenosis greater than 60% as a cause of cerebral ischemia.
The Carotid and Vertebral Transluminal Angioplasty Study (CAVATAS
) (30-31) was a large, prospective, randomized, multicenter trial that compared CAE with carotid angioplasty in patients with symptomatic stenosis of at least 70%.
Results from the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS
), which were published in 2001, showed that in 504 low- to moderate-risk patients, carotid angioplasty or angioplasty and stenting was as effective as endarterectomy for preventing stroke or death.
