Why is it called a frozen elephant trunk?

Why is it called a frozen elephant trunk? The so-called frozen elephant trunk technique is adapted from the classic elephant trunk technique first described by HG Borst in 1983 and allows the concurrent repair of the aortic arch and descending aortic aneurysms proximal in one step.

What is a Frozen Elephant Trunk? The frozen elephant trunk (FET) procedure, or open stent, is a tool for the combined open and endovascular treatment via median sternotomy of extensive aortic disease involving both the aortic arch and the descending thoracic aorta. .

What is the frozen elephant trunk made of? This new option has been called frozen elephant trunk. The device described in this report is an E-vita open hybrid prosthesis (Jotec, Hechingen, Germany) consisting of a proximal woven polyester tube graft and a distal self-expanding nitinol stent available in diameters of 24 at 40mm.

What is an Elephant Trunk Procedure? The elephant trunk procedure is a two-step procedure used to treat extensive aneurysms involving both the ascending aorta and aortic arch, and the descending thoracic or thoracoabdominal aorta.

Why is it called frozen elephant trunk – Related questions

Who invented Evar?

On , Dr. Parodi teamed up with vascular radiologist Julio Palmaz, MD, to perform the world’s first successful Endovascular Aneurysm Repair (EVAR). The minimally invasive procedure was performed under local anesthesia in a 70-year-old man with severe back pain associated with a 6 cm abdominal aortic aneurysm.

What is the frozen elephant technique?

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

What is the aortic arch?

The aortic arch is the upper part of the main artery carrying blood away from the heart. Aortic arch syndrome refers to a group of signs and symptoms associated with structural problems in the arteries that branch off from the aortic arch.

What is type A dissection?

Type A dissection occurs when the tear develops in the ascending part of the aorta just as it branches from the heart, while type B dissection involves the lower aorta. Although type A dissection is the most dangerous form, chances of survival are greatly improved with early detection and management.

What is the function of the aorta?

The aorta is the large artery that carries oxygen-rich blood from the left ventricle of the heart to other parts of the body.

What is type A and type B aortic dissection?

Aortic dissections are classified into two types: type B dissection involves a tear in the descending part of the aorta and may extend into the abdomen, while type A dissection develops in the ascending part of the aorta. aorta as it branches from the heart.

How long does a synthetic aorta last?

In the Aortic Program, a repaired valve should have a lifespan of ten years or more (comparable to the minimum wait for a bioprosthesis).

Can you replace the whole aorta?

A staged replacement of the entire aorta from the ascending arch to the hypogastric arteries using a hybrid approach. Combined open and endovascular hybrid procedures can be used to treat complex aortic pathology.

How long does the repair of an ascending aortic aneurysm take?

The operation can take 5 hours or more. You may need several surgical repairs in your lifetime. It depends on the health of the aortic valve and heart arteries. You will have a general anesthetic to make you comfortable and sleep during the surgery.

What does Endoleak mean?

An endoleak is a complication that affects approximately 15-25% of patients who have EVAR. This means that some amount of blood flow still remains in the aneurysm cavity.

What is the difference between EVAR and tevar?

EVAR: EndoVascular Repair of Aortic Aneurysms, TEVAR: Thoracic EndoVascular Repair of the Aorta. There are many types of diseases of the main artery of the body, also known as the aorta.

What does tevar mean?

Thoracic Aortic Endovascular Repair (TEVAR) is a procedure to treat an aneurysm in the upper part of your aorta.

What is the Dacron graft?

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

What is the largest vein in the body?

Did you know that your great saphenous vein is the longest vein in the human body? Stretching from the top of your foot to your upper thigh and groin, THIS vein is the main culprit of varicose veins.

What is the Circle of Willis?

The circle of Willis is the area where several arteries join on the lower (lower) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the brain.

What is the aortic joint?

Knob or aortic joint refers to the frontal appearance on chest radiograph of the distal aortic arch as it curves posterolaterally to continue as the descending thoracic aorta. It appears as a laterally projecting bulge because the medial aspect of the aorta cannot be seen separately from the mediastinum.

What is LOEY-Dietz syndrome?

Loeys-Dietz syndrome (LDS) is a disorder that affects the connective tissues of the body and increases the risk of aneurysms in arteries such as the aorta. This condition is rare and was only recently identified as a condition in 2005.

What is the worst type A or B aortic dissection?

Type A is the most common type of aortic dissection and is more likely to be acute than chronic. This makes it more dangerous than type B dissections because it is more likely to rupture the aorta, leading to life-threatening heart disease.

On which side of the body is the aorta?

The aorta, normally on the left side of the body, can be found on the right in dextrocardia, in which the heart is on the right, or situs inversus, in which the location of all organs is reversed. Variations in the branching of individual arteries may also occur.

How long can you live with a type B aortic dissection?

Despite adequate antihypertensive therapy, the long-term prognosis of these patients is characterized by significant aortic aneurysm formation in 25 to 30% at four years, and survival rates of 50 to 80% at five years and 30 to 60% at 10 years.

What is the survival rate for type B aortic dissection?

The actuarial survival rate was 89.4% at 5 years and 71.8% at 10 years.
