Aortic Aneurysm (Definition)

"Aneurysm" has scary implications for many people. It just means an enlargement of an artery. The problem is that when arteries (including the aorta) get too large, their walls become weak and prone to tear (dissection) or rupture. If this happens in the aorta it can be a catastrophe. Management of aortic aneurysms depends on where it is, how big, whether it's growing, ...Read more

Rare type is infected or inflammatory /fever. ...Read more

Dilated aorta: Approx. 75% of aortic aneurysms are infrarenal. If the diameter of the aneurysm increases >= 0.5 cm/6mo. Period, early intervention advised. Once the aneurysm is 5cm or about twice the diameter of the non involved aorta, elective repair is advised. If 4cm dia and enlarging, repair advised to lower risk of death from exanguinating rupture.

Can you diagnose abdominal aortic aneurysm with a stethoscope?

No: You may hear a noise- bruit.

Surgery observation: Small aneurysms (less tha 5 cm) are typically followed with ultrasound unless there are factors that worry the doc. Surgery may be done with an abdominal incision - to open the aneurysm and replace it with a plastic graft. More recently, endovasculat techniques enable stenting of the ane3urysm and use smaller incisions. ...Read more

Size: Abdominal aneurysms should be treated surgically if greater than or equal to 6 cm (sometimes 5.5 cm depending on the age and risks), if symptomatic or if it grows at a rate greater than 0.5 cm/ 6 months.
The treatment is endovascular repair unless the anatomy is unfavorable (unusual).
You should see a board certified vascular surgeon with endovascular experience. ...Read more

SEVERAL: If it is not tool larger, medicines to control your blood pressure will help prevent it from getting larger. However, if it is expanding rapidly or is large, then there is the danger of it rupturing, which could be fatal. Depending on the location and size, sometimes this can be repaired with a stent meaning that no incision is necessary. Otherwise, an open operation is needed. ...Read more

Why is the abdominal aortic aneurysm more common?

Less wall elastin: The aorta, the main artery that delivers blood from the chest to the belly, has a protein known as elastin in its wall. Smoking and COPD affect biochemistry destroying elastin, leading to weakening in the wall causing it to bulge out forming an aneurysm. Why most common in abdomen? Cause elastin layer is thickest in chest thins at renal arteries in abdomen - no surprise they often form there 1st! ...Read more
