Endovascular treatment of aortic aneurysms: techniques and clinical update

Open repair of abdominal and thoracic aortic aneurysms continues to be associated with considerable morbidity and mortality. Endovascular repair of abdominal and thoracic aortic aneurysms has evolved over the past few years and has significantly reduced the morbidity of aortic aneurysm repair compared with the standard open surgical procedures. Several devices have been approved for clinical use for this purpose. This has allowed the treatment of patients who are otherwise at high risk for open repair. This review paper aims to (1) describe the general principles of use for endovascular devices and review the radiographic features and clinical trials for the devices in current use, (2) present the results of the clinical trials that led to the approval and marketing of the current devices, and (3) review new techniques and approaches for the treatment of aortic aneurysms.
