What is frozen elephant trunk technique?

What is frozen elephant trunk technique?

A relatively new approach is the frozen elephant trunk (FET) technique, which potentially allows combined lesions of the thoracic aorta to be treated in a 1-stage procedure combining endovascular treatment with conventional surgery using a hybrid prosthesis.

Why is it called frozen elephant trunk procedure?

Abstract. The so-called ‘frozen elephant trunk’ technique is adapted from the classical elephant trunk technique first described by H.G. Borst in 1983 and allows the repair of concomitant aortic arch and proximal descending aortic aneurysms in a single stage.

What is frozen elephant trunk made of?

This new option was termed frozen elephant trunk. The device described in this report is an E-vita open hybrid prosthesis (Jotec, Hechingen, Germany) made out of a proximal woven polyester tube graft and a distal self-expandable nitinol stent graft available in diameters of 24 to 40 mm.

What is an elephant trunk procedure?

The elephant trunk procedure is a two-stage procedure used to treat extensive aneurysms involving both the ascending aorta and aortic arch, and the descending thoracic or thoracoabdominal aorta.

What is tevar procedure?

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. TEVAR is a minimally invasive surgery.

What is Hemiarch replacement?

Hemiarch replacement is defined as the proximal arch repair beyond the level of the innominate artery without involving the arch vessels, and total arch replacement is the replacement of supra-aortic vessels as an island or individual branched grafts.

Can a stent be put in the aortic arch?

Aortic arch stenting is a safe procedure. Aortic arch stenting results in a decrease in systolic blood pressure. Aortic arch stenting results in a decrease in need for antihypertensive medication.

How long does a synthetic aorta last?

At the Aortic Program, a repaired valve is expected to have a life of ten years or more (comparable to the minimum expectation for a bioprosthesis).

Is TEVAR heart surgery?

TEVAR is a minimally invasive surgery. That means it is done with a small cut (incision). With TEVAR, a device called a stent graft is used to reinforce the aneurysm.

How long does a Dacron aorta last?

The function of the aortic valve implanted inside a tubular Dacron graft remains normal at 15 years in most patients after this type of aortic valve–sparing operation.
