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 a GORE TEX vascular graft?

Improving grafting in peripheral, aortic, and vascular access procedures. In vascular surgery, superior graft performance is essential. A vascular graft must be inert and biocompatible, as well as strong, conformable and easy-to-handle.

What is an endoluminal graft?

What is endovascular grafting? Endovascular grafting is a minimally invasive method to treat an aortic aneurysm. Instead of an open aneurysm repair in which your chest/abdomen are surgically opened, your surgeon may consider a procedure called an endovascular aneurysm repair (EVAR).

What is Dacron graft?

A synthetic polyester graft (such as Dacron) is sutured to the aorta to repair an ascending aortic aneurysm.

What is PTFE graft?

PTFE Grafts PFTE, also known as Teflon, is a synthetic material, readily available. It has been shown that PTFE grafts are easy to implant, cannulate with ease and carry a relatively low rate of infection. PTFE grafts can typically be used for dialysis within 2-3 weeks.

What is Gore Tex graft made of?

It is composed of stretched polytetrafluoroethylene (PTFE), which is more commonly known by the generic trademark Teflon. The material is formally known as the generic term expanded PTFE (ePTFE).

What is a vascular graft used for?

A vascular graft (also called vascular bypass) is a surgical procedure that redirects blood flow from one area of the body to another by reconnecting the blood vessels.

What are vascular grafts made of?

Expanded polytetrafluoroethylene, Dacron® and polyurethane are currently used as synthetic vascular grafts. Polyurethane is better able to match the compliance of native vasculature, but the patency rates of grafts composed of synthetic, nondegradable materials is relatively poor.

What is an Acuseal graft?

The GORE® ACUSEAL Vascular Graft allows for earlier removal or avoidance of a central venous catheter (CVC), providing an alternative for your hemodialysis patients. Early cannulation: Cannulate within 24 hours with the leading1 on-label early cannulation graft to allow for earlier removal or avoidance of a CVC.

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 a Type 2 graft leak?

Type II endoleak: Type II endoleaks are the most common. These are leaks that happen when blood flows into the aneurysm sac from branches of the aorta, or other blood vessel treated with a stent. The blood flows into the aneurysm sac cavity through small branches which enter the treated aneurysm.

Can you live a normal life after aortic aneurysm repair?

The study found that short-term crude, or actual, survival rates improved among patients who underwent surgery to repair a ruptured abdominal aortic aneurysm. The relative survival rate held steady at about 87 percent. On average, patients who underwent repair for a ruptured aneurysm lived 5.4 years after surgery.

What is ascending aorta graft?

The procedure involves excision of the ascending aorta and underside of the aortic arch, and placement of a thoracic aortic stent graft into the descending aorta at the time of arch repair. The native aortic valve and root are repaired, and the ascending aorta and proximal arch are replaced with a Dacron graft.

What is aorta graft surgery?

The surgical removal of some portion of diseased aorta is called aortic resection. A polyester graft is used to replace the diseased aortic tissue. The polyester grafts (such as Dacron) are an excellent example of successful substitution of a synthetic material within the human body.

What is the aortic root?

The aortic root is the section of the aorta closest to and attached to the heart. An aneurysm is an abnormal bulge in the wall of an artery. If the aneurysm develops in the aortic root, the aorta can dilate and the aortic valve can leak (regurgitation).

What is Nonautogenous graft?

Non-autogenous grafts are available either as allogeneic or xenografts. Allogenic bone grafts are obtained from genetically dissimilar donors of the same species, whereas xenografts are obtained from a different species [27]. These grafts are available as mineralized, demineralized, fresh, frozen, or freeze-dried bone.

What is polytetrafluoroethylene used for?

Polytetrafluoroethylene is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals.

What does PTFE mean?

Polytetrafluoroethylene Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties.

Why is Gore Tex so good?

GORE-TEX is an amazing breathable, waterproof textile found in high-performance clothes such as walking/hiking boots and mountain coats. Unlike ordinary synthetic textiles like nylon, GORE-TEX stops rain from getting in but lets perspiration out.

How long does a vascular graft last?

In general, a vein bypass in the leg can be expected to last five years or longer in 60 to 70 percent of patients, although about one-quarter to one-third will require additional procedures to maintain the function of these grafts.

What is the difference between a graft and a stent?

Blood Vessels Theoretically, the graft creates a barrier to exclude diseased arterial wall and provides a smooth flow conduit, while the stent support affixes the graft and may enhance luminal patency by resisting external compression.

How does vascular grafting work?

Grafting: Once the bypass site is exposed and the graft is harvested, the surgeon will sew the graft into a tiny opening below the diseased artery. The other end of the graft will be sewed to another part of a healthy artery.

What are the types of vascular grafts?

In general, someone’s own vein (autograft) is the preferred graft material (or conduit) for a vascular bypass, but other types of grafts such as polytetrafluoroethylene (Teflon), polyethylene terephthalate (Dacron), or a different person’s vein (allograft) are also commonly used.

What is a vessel grafting?

Coronary artery bypass surgery restores normal blood flow to the heart by creating a “detour” (bypass) around the blocked artery/arteries. This is done by using a healthy blood vessel, called a graft. Grafts usually come from your own arteries and veins located in the chest, leg or arm.

When are vascular grafts used?

Vascular grafts are used on damaged or diseased blood vessels, when surgeons need to redirect blood flow by replacing the blood vessel, oftentimes by using synthetic grafts (Keefer, 2003).

How long does it take to heal from vascular surgery?

Avoid standing for long periods or sitting with your feet down (elevate your feet whenever you sit). Expect a full recovery in approximately 4 to 8 weeks.

What is a vein graft in the leg?

A vein taken from another area in your leg is attached above and below the blockage. This is called a graft. The blood is rerouted through the graft around the blockage. In some cases, a man-made graft may be used, rather than a vein graft. Percutaneous transluminal angioplasty (PTA) of the femoral arteries.

What is Propaten?

The PROPATEN graft is an artificial vascular graft made from ePTFE and coated on the inner (luminal) surface with low molecular weight heparin (CBAS 2-heparin). The graft incorporates stretch technology which is intended to improve anastomotic compatibility, length forgiveness and kink resistance.

What is Acuseal?

The GORE ACUSEAL Graft is a new trilayer graft that has been cleared by the US Food and Drug Administration for vascular access and has the claim of early cannulation. The use of this graft has the potential to shift the paradigm of catheter usage.
