What is an endograft?
A device known as an endoluminal stent graft (or endograft) can be placed inside the thoracic portion of the aorta to provide support for the weakened artery. This endograft is a hollow, fabric-covered tube, surrounding a mesh metal cylinder (or stent).
What is an endograft made of?
Zenith endografts are composed of woven polyester fabric and Gianturco stainless-steel stents.
What does TEVAR stand for?
Thoracic endovascular aortic repair (TEVAR) is a procedure to treat an aneurysm in the upper part of your aorta. The aorta is your body’s largest artery. An aneurysm is a weak, bulging area in the aorta wall. If it bursts (ruptures), it can be deadly.
What is the difference between EVAR and TEVAR?
Endovascular aortic aneurysm repair (EVAR) is a surgery used to treat an abdominal aortic aneurysm (AAA). For a patient with a thoracic aortic aneurysm (aneurysm in the chest area), the procedure is termed thoracic endovascular aortic aneurysm repair (TEVAR).
What is a fenestrated endograft?
Fenestrated and branched endografts are stents (small metal scaffolds or tubes) that have reinforced openings (fenestrations) or branches that allow the physician to attach arteries that lead to other organs.
What is AAA endograft?
Endovascular Stent Systems for Repair of Abdominal Aortic Aneurysms. Endovascular stents (endografts) are used to repair AAAs within the blood vessel without open surgery. They are generally composed of a metal frame covered with a woven polyester material that is similar to the standard surgical grafts.
What is an endograft repair?
Endovascular stents (endografts) are used to repair AAAs within the blood vessel without open surgery. They are generally composed of a metal frame covered with a woven polyester material that is similar to the standard surgical grafts.
What is fenestrated endograft?
In a fenestrated endovascular repair, surgeons create holes called fenestrations in the endograft to accommodate blood flow to the branch vessels of the kidneys, small bowel and liver. The surgeon customizes the holes in the endograft for each patient based on their individual anatomy.
What is a tebar?
Tébar is a municipality located in the province of Cuenca, Castile-La Mancha, Spain. According to the 2004 census (INE), the municipality has a population of 387 inhabitants.
What is a frozen elephant trunk procedure?
Abstract. The frozen elephant trunk (FET) procedure, or open stent grafting, is a tool for the combined open and endovascular treatment via a median sternotomy of extensive aortic disease involving both aortic arch and descending thoracic aorta.
Who performs TEVAR?
In these cases, cardiac surgeons perform endovascular aneurysm repair using branched, or fenestrated, endografts. Your surgeon uses the same TEVAR technique to advance a graft to the diseased region of the aorta. They then expand it so the branches on the graft extend into the natural branches protruding off the aorta.
Where is a thoracic aneurysm?
“Thoracic” refers to the part of the aorta that runs through the chest (thoracic aortic aneurysm). Aneurysms occur more often in the portion of the aorta that runs through the abdomen (abdominal aortic aneurysm).
What is an endoleak after endograft surgery?
Once an endograft has been placed, there is a need for long-term surveillance to ensure that the graft remains in the correct position, that flow through the graft is normal and that the aneurysm is not expanding. An “endoleak” is present if there is flow in the aneurysm sac outside the endograft.
What does xenograft mean in medical terms?
medical Definition of xenograft. : a graft of tissue taken from a donor of one species and grafted into a recipient of another species — called also heterograft, heterotransplant, xenotransplant; compare homograft. —.
Is there a relationship between Endograft migration and thrombosis?
Although potential risk of endograft migration and thrombosis can be evaluated using computational simulation and in vitro experiment, the conclusion is a preliminary conclusion and needs further study.
What is a heterograft?
: a graft of tissue taken from a donor of one species and grafted into a recipient of another species — called also heterograft, heterotransplant, xenotransplant; compare homograft.
