Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
Prior to the advent of endovascular aneurysm repair (EVAR), OAS was the only surgical treatment available for aortic aneurysms. The shift away from open aortic surgery towards endovascular surgery since 2003 has been driven by worse perioperative mortality associated with OAS, particularly in patients in relatively frail health.

Endovascular coiling is an endovascular treatment for intracranial aneurysms and bleeding throughout the body. The procedure reduces blood circulation to an aneurysm or blood vessel through the implantation of detachable platinum wires, with the clinician inserting one or more into the blood vessel or aneurysm until it is determined that blood flow is no longer occurring within the space.
Patients with aneurysms which have a diameter less than 5 cm are at <1% rupture risk per year. When the aneurysm meets size criteria it can be treated with aortic replacement or EVAR. Thoracic. Thoracic aortic aneurysms are contained in the chest. Aneurysms of the descending aorta can often be treated with thoracic endovascular aortic repair or ...
An aortic aneurysm can occur as a result of trauma, infection, or, most commonly, from an intrinsic abnormality in the elastin and collagen components of the aortic wall. Aortic aneurysm development and progression have been directly associated with a deficiency of elastin as well as a loss of collagen type 1. [19]
Ohio woman underwent 12 procedures. Between Jan. 5 and Feb. 14, Smith underwent at least 12 procedures to treat the brain aneurysm, according to her husband.
A true aneurysm is one that involves all three layers of the wall of an artery (intima, media and adventitia).True aneurysms include atherosclerotic, syphilitic, and congenital aneurysms, as well as ventricular aneurysms that follow transmural myocardial infarctions (aneurysms that involve all layers of the attenuated wall of the heart are also considered true aneurysms).
