Carotid angioplasty-stenting (CAS) is a relatively new endovascular procedure that has been used increasingly in recent years. Its popularity is due to, at least in part, the perceived advantages of a less invasive treatment for extracranial carotid occlusive disease. However, valid data that contrast the efficacy of CAS and carotid endarterectomy (CEA), the gold standard for the treatment of symptomatic carotid stenosis, are not available. ⋯ Men and women will be eligible for the trial, but patients with medical conditions likely to limit their participation during the follow-up or to interfere with outcome evaluation will be excluded. After a credentialing and training phase, 2500 patients will be randomized to the treatments. Statistical analysis of the primary outcome will use standard survival methods.

Comparative Study
Age versus comorbidities as risk factors for complications after elective abdominal aortic reconstructive surgery.
This study estimated the association between age and in-hospital postoperative complications, controlling for known or suspected risk factors, in a series of patients undergoing elective abdominal aortic reconstructive surgery (AAR). ⋯ For patients undergoing elective AAR, increasing patient age is associated with a small increase in risk for in-hospital morbidity or mortality. However, significant cardiac, pulmonary, or renal disease is associated with a much greater risk of postoperative complications, and, therefore, advanced age should not be the sole basis of exclusion for otherwise suitable candidates for elective AAR.

The purpose of this study was to determine the current outcome in the United States and to identify predictors of mortality and "bad outcome" after open, intact abdominal aortic aneurysm (AAA) repair. ⋯ Outcome after open repair of intact AAA across the United States is quite good. Older, sicker patients may benefit from nonoperative treatment or the potentially lower risk endovascular approaches.

As a minimally invasive strategy for the treatment of patients with abdominal aortic aneurysm (AAA), endovascular repair has been embraced with enthusiasm because of the promise of achieving a durable result with a reduced risk of perioperative morbidity and mortality. Our mid-term experience with endovascular AAA repair was assessed by examining early and late clinical outcome in concurrent cohorts of patients stratified either as low-risk or as at increased-risk for intervention. ⋯ Despite the use of an endovascular approach for aneurysm treatment, the risk of perioperative death and morbidity remains present for all patients including those who have no significant medical comorbidity. Moreover, although clinical success rates are comparable in both patient groups, 2 years after endovascular repair was performed, at least one in four patients was classified as a clinical failure. Given the continued uncertainty associated with clinical outcome and the need for close life-long surveillance, caution is dictated in advocating endovascular treatment for the patient who is otherwise considered an ideal candidate for standard open surgical repair.
