Whether elective endovascular repair of abdominal aortic aneurysm reduces long-term morbidity and mortality, as compared with traditional open repair, remains uncertain.We randomly assigned 881 patients asymptomatic aneurysms who were candidates for both procedures to either (444) or (437) followed them up 9 years (mean, 5.2). Patients selected from 42 Veterans Affairs medical centers 49 age older at the time registration.More than 95% underwent repair. For primary outcome all-cause 146...

Previous clinical trials have suggested that carotid-artery stenting with a device to capture and remove emboli ("embolic protection") is an effective alternative carotid endarterectomy in patients at average or high risk for surgical complications.In this trial, we compared embolic protection 79 years of age younger who had severe stenosis were asymptomatic (i.e., not stroke, transient ischemic attack, amaurosis fugax the 180 days before enrollment) considered be complications. The trial...

Elective endovascular repair of an abdominal aortic aneurysm results in lower perioperative mortality than traditional open repair, but after 4 years this survival advantage is not seen; addition, two European trials have shown worse long-term outcomes with repair. Long-term a study we conducted more decade ago to compare are unknown.We randomly assigned patients asymptomatic aneurysms either or the aneurysm. All were candidates for procedure. Patients followed up 14 years.A total 881...

Angioplasty and stenting are options for revascularization of symptomatic femoral popliteal disease. Although angioplasty alone is effective in short lesions, longer lesions often treated with stents. Multiple overlapping stents expensive may be associated stent fracture. This trial evaluated the safety efficacy a single self-expanding up to 20 cm length patients atherosclerotic disease superficial artery (SFA) proximal artery.Patients >4 <18 were enrolled this nonrandomized, prospective,...

<h3>Importance</h3> Abdominal aortic aneurysms affect more than 3% of US older adults. <h3>Objective</h3> To test whether doxycycline reduces the growth abdominal aneurysm over 2 years as measured by maximum transverse diameter. <h3>Design, Setting, and Participants</h3> Parallel, 2-group, randomized clinical trial that was conducted at 22 centers between May 2013 January 2017, enrolled patients 50 or with small (3.5-5.0 cm for men, 3.5-4.5 women) infrarenal aneurysms. The final date...
