What is 3.7 cm infrarenal aortic aneurysm?

A 3.7cm infrarenal aortic aneurysm refers to a localized bulge or enlargement in the abdominal aorta, the main artery that supplies blood to the abdomen and lower body. The aneurysm occurs in the portion of the aorta located below the renal arteries, which supply blood to the kidneys.

The size of the aneurysm is measured in centimeters (cm). In this case, the aneurysm measures 3.7 centimeters in diameter. Aneurysms are considered to be large when they reach a diameter of 5 centimeters or more.

Infrarenal aortic aneurysms are relatively common, especially in older individuals and those with certain risk factors, such as smoking, high blood pressure, and atherosclerosis (hardening of the arteries). They can cause a range of symptoms, including abdominal pain, back pain, and a pulsating sensation in the abdomen. However, many aneurysms do not cause any symptoms and are discovered during routine medical examinations.

Treatment for infrarenal aortic aneurysms depends on their size and the patient's overall health. Small aneurysms may be monitored closely with regular imaging tests to track their growth. Larger aneurysms or those that are causing symptoms may require surgical repair, either through traditional open surgery or less invasive endovascular techniques.
