What is a fenestrated graft?

A fenestrated endovascular graft is a type of aortic stent-graft with branches for other blood vessels. They can treat aortic aneurysms near your kidneys or complex aneurysms in blood vessels leading to other organs. Your care team uses high-tech CT scans to find and measure your aneurysm.

What is endoluminal grafting?

An abdominal aortic aneurysm is a bulge in the aorta (the main blood vessel coming from the heart) in the abdomen. To repair the aneurysm, the doctor uses a catheter (thin, flexible tube) to guide a graft through a blood vessel and place it inside the aneurysm.

What are stent grafts made of?

Stent grafts comprised of metal struts covered with fabric made of Dacron/polyester or polytetrafluoroethylene were developed for the purpose of achieving an adequate seal at the proximal and distal aspects of thoracic aneurysms, thus excluding sac flow.

What is bifurcated graft?

The bifurcated system developed involves a trouser graft with one long leg and one short. This graft-system is delivered through one femoral artery with deployment of the proximal aortic end infrarenally and the longer trouser leg within the ipsilateral common iliac artery.

What is fenestrated repair?

Fenestrated Endovascular Aortic Repair, also known as FEVAR, is a minimally invasive procedure that allows surgeons to repair the aorta through small incisions in your groin and or arms while still preserving blood flow to the critical branch arteries to your kidneys and other organs.

What is Dacron graft?

A Dacron graft is made out of a man-made (synthetic) polyester material. It is used to replace natural body tissues. Most Dacron grafts are in the shape of a tube to replace or repair blood vessels.

What is AAA Infrarenal?

The standard definition for an infrarenal AAA is a transverse aortic diameter ≥3.0 cm. Other studies have used a definition of 1.5 to 2.0 times the normal adjacent aortic diameter.

What is a fenestrated device?

What is a fenestrated AAA repair?

What is a branched EVAR?

Branched EVAR provides a solution when the target vessels arise from a segment of the aneurysmal aorta. A branched stent graft is deployed in a dilated aorta and, therefore, there is a gap created between the target vessels and stent graft, which requires bridging.

What is a Hemashield graft?

The HEMASHIELD PLATINUM Woven Double Velour Vascular Graft is designed to reduce bleeding at implant and thereby eliminates the operative preclotting step, including cumbersome autoclave techniques. The collagen is designed to be gradually resorbed by the patient.

Where is the infrarenal aorta?

The aorta delivers oxygenated blood pumped from the heart to the rest of the body. The most common location of arterial aneurysm formation is the abdominal aorta, specifically, the segment of the abdominal aorta below the kidneys. An abdominal aneurysm located below the kidneys is called an infrarenal aneurysm.

What is a branched stent graft?

Branch artery stenting Open and covered stents may be used to hold the margin of the stent graft away from the orifice of a branch artery and preserve a channel for branch artery perfusion. In the aortic arch, the additional stent is best inserted through downstream access to the branch artery itself.
