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. [2]
Should initial medical management fail or there is the involvement of a major branch of the aorta, vascular surgery may be needed for these type B dissections. Treatment may include thoracic endovascular aortic repair (TEVAR) with or without extra-anatomic bypass such as carotid-carotid bypass, carotid-subclavian bypass, or subclavian-carotid ...
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."
The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated with Marfan syndrome.
Aortic valve repair or aortic valve reconstruction is the reconstruction of both form and function of a dysfunctional aortic valve. Most frequently it is used for the treatment of aortic regurgitation. [1] It can also become necessary for the treatment of aortic aneurysm, less frequently for congenital aortic stenosis.
In 1963, Christiaan Barnard and Velva Schrire were the first to use DHCA to repair an aortic aneurysm, cooling the patient to 10 °C. [13] Randall B. Griepp , in 1975, is generally credited with demonstrating DHCA as a safe and practical approach for aortic arch surgery.
If the left sided outflow root needs to be enlarged to fit the pulmonary autograft, the procedure is called Ross-Konno. [3] An alternative to a pulmonary homograft is the stentless xenograft roots such as the Freestyle Porcine Aortic Root by Medtronic. [2] [12] An external Dacron graft can be used to reinforce the pulmonary autograft. [2]
[2] [3] The implantated valve is delivered via one of several access methods: transfemoral (in the upper leg), transapical (through the wall of the heart), subclavian (beneath the collar bone), direct aortic (through a minimally invasive surgical incision into the aorta), and transcaval (from a temporary hole in the aorta near the navel through ...
