Thoracic aortic stent-grafting.

The surgical management of thoracic disease has improved steadily over the past 20 years due to advances in diagnostic and surgical techniques. Despite this progress, a less invasive approach to treatment is desirable. Patients with coexisting cardiovascular or pulmonary diseases may not tolerate aortic replacement under general anesthesia, particularly combined with extracorporeal bypass. Endovascularly placed stent-grafts offer an alternative therapy, which is less invasive and associated with a shorter hospital recuperation time than with traditional operative therapy. The authors discuss the development of stent-grafts for use in the thoracic aorta, along with the various techniques utilized during these complex procedures.
