What is an infrarenal aortic aneurysm?


What is an infrarenal aortic aneurysm?

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 intraluminal thrombus?

Intraluminal thrombus (ILT) thickness (red arrow) is defined as the distance from the ventral aneurysm wall to the aortic lumen in the anteroposterior direction on the orthogonal slices.

When should an infrarenal abdominal aortic aneurysm be repaired?

The indication for repair includes either symptomatic aneurysms or aneurysms with a diameter greater than 5.4 cm. Treatment options for the repair of infrarenal aortic aneurysms are open surgical repair (OSR) and endovascular aneurysm repair (EVAR).

How is aortic thrombosis treated?

Therapeutic options are surgical removal, either by aortotomy with endarterectomy, thrombectomy or balloon embolectomy, thrombolysis or anticoagulation [1–10]. We present a case in whom a large, highly mobile thrombus in the descending aorta resolved during therapy with heparin and phenprocoumon.

Can you live with an aortic aneurysm?

Yes, you can live with an aortic aneurysm, and there are many ways to prevent dissection (splitting of the blood vessel wall that causes blood to leak) or worse, a rupture (a burst aneurysm). Some aortic aneurysms are hereditary or congenital, such as bicuspid aortic valve, infection or inflammatory conditions.

What is the difference between thrombosis and aneurysm?

The main difference between an aneurysm and embolism or thrombosis is that the latter two involve blockages, while an aneurysm involves damage to the artery wall. Aneurysms can result from high blood pressure or smoking. A person can also be born with one.

What are the outcomes of thrombosis?

There are 5 main outcomes of thrombosis: lysis, organisation, occlusion, embolism & propagation. Embolism & occlusion will be covered in more detail in later Pathologia modules. 2. Propagation – occurs if a vein is completely occluded.

What causes aortic thrombosis?

Most cases of arterial thrombosis are caused when an artery is damaged by atherosclerosis. Fatty deposits build up on the walls of the arteries and cause them to harden and narrow.

What are the symptoms of arterial bleeding?


  • Cold arm or leg.
  • Decreased or no pulse in an arm or leg.
  • Lack of movement in the arm or leg.
  • Pain in the affected area.
  • Numbness and tingling in the arm or leg.
  • Pale color of the arm or leg (pallor)
  • Weakness of an arm or leg.
