Endovascular stent-grafts for the treatment of abdominal aortic aneurysms: NICE technology appraisal guidance.

چکیده
Stent grafting for treatment of abdominal aortic aneurysms (AAAs) has been a major advance in endovascular surgery. Initial success with the original endoluminal stent graft encouraged worldwide study of the technology. In the United States, the Food and Drug Administration (FDA) insisted on considerable experience with the devices before approval because of early problems with device rupture, stent fracture, fabric perforation, graft migration, and modular separation. Complications associated with the endovascular graft technology led many to recommend its use only in patients who were considered at "high risk" for the standard, open procedure. Further study and device improvements have led to results that indicate the procedure has the potential to reduce operating time and blood loss and shorten intensive care unit and hospital stays compared with open surgical intervention. At present, there are three FDA-approved devices available for use, and a fourth is expected in 2003. The ultimate decision by the individual practitioner or the institutional team regarding which patients should be treated with endovascular technology is still not entirely straightforward. Patient selection should be based on vascular anatomy, the availability of a suitable device, the patient's desire for a minimally invasive procedure, and a commitment to what is likely to be a lifetime of device surveillance.

endovascular devices and techniques will evolve to expand applicability and provide therapy for most aortic diseases, including a growing number of diseases of the arch and the ascending aorta [4]. Complex aortic aneurysms that involve major aortic branch origins include those juxtaposed or involving the renal arteries (juxtarenal, perirenal), the visceral arteries (thoraco-abdominal) and the g...
متن کاملEndovascular stent grafting of descending thoracic aortic aneurysms.
The treatment of descending thoracic aortic aneurysms using endovascular stents is one of the more recent advances in treatment and is receiving increasing attention as it is a less invasive alternative to open surgical repair. Although the technology is still primitive, significant improvements have lately been made in the design and deployment of the endovascular stent-grafts. Aortic stent-gr...

BACKGROUND Recently, thoracic aortic stent grafting has emerged as an alternative therapeutic modality for patients with thoracic aortic aneurysms and aortic dissections. However, its application has been limited to descending thoracic aortic aneurysms distal to the aortic arch. We report our initial clinical experience of endovascular branched stent graft repair for aortic arch aneurysms. ME...

Mycotic aortic aneurysms account for 1–3% of all aortic aneurysms. The management of this disease is controversial. Since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown.Secondary aortoenteric fistulas may occur iatro...
