What size descending aortic aneurysm requires surgery?

The 2017 European Society for Vascular and Endovascular Surgery (ESVS) guidelines on descending thoracic aortic disease suggested that endovascular repair should be considered for descending TAAs > 60 mm diameter, as this is the diameter where risk of rupture sharply escalates (classification IIa, level B evidence).

What is a descending aortic aneurysm?

Aortic arch, the part of the aorta that arches and turns downward before it becomes the descending aorta. Descending aorta, which branches into the thoracic and abdominal aorta. A descending aortic aneurysm that extends to the abdomen is a thoracoabdominal aneurysm. Abdominal aorta, which is located below the diaphragm.

What is the success rate of aortic aneurysm surgery?

Surgical procedures for the repair of abdominal aortic aneurysms have a high success rate, with more than 95 percent of patients making a full recovery.

How long does aortic stent last?

Current generation stent grafts correlated with significantly improved outcomes. Cumulative freedom from conversion to open repair was 93.3% at 5 through 9 years, with the need for prior reintervention (OR, 16.7; P = 0.001) its most important predictor. Cumulative survival was 52% at 5 years.

How to diagnose a descending thoracic aortic aneurysm?

Diagnosing A Descending Thoracic Aortic Aneurysm. If you have a descending thoracic aortic aneurysm, you may experience severe or dull pain in the abdomen, chest, lower back or groin and/or sharp, sudden pain in the back or abdomen. Our specialists can diagnose you through a series of tests, including: Chest X-ray.

What is the anatomy of a descending aorta?

The descending aorta provides important blood flow to the spinal cord. The anatomy of the descending aorta makes it more favorable for endovascular approaches in some cases, however, more complex problems will still require open surgery. Aneurysms involving the descending and abdominal aorta are classified as thoracoabdominal aortic aneurysms.

Are there any surgical options for descending aortic aneurysms?

DESCENDING THORACIC AORTIC ​ANEURYSMS. The gold standard for repair of descending aortic aneurysms is open surgical repair. However, certain diseases of the descending thoracic aorta lend themselves to endovascular therapies. In addition, patients who are old and frail and with many medical problems, specifically,…

Can a descending aorta be replaced with a Dacron graft?

Thoracoabodominal Aortic Aneurysm (TAAA) – Extent II. This procedure is indicated for aneurysmal disease involving the entire descending aorta and extending below the diaphragm to involve the entire abdominal aorta. The aorta is replaced from the left subclavian artery to the infrarenal aorta with a Dacron graft.
