What is bifurcation of aorta?

Bifurcation of the aorta refers to the point where the aorta, the largest artery in the body, splits into two branches known as the left and right common iliac arteries. This occurs in the lower abdomen near the level of the fourth lumbar vertebra, typically at the level of the navel.

The bifurcation of the aorta is an important anatomical landmark and plays a critical role in the circulation of blood throughout the lower body. It supplies oxygen-rich blood to the pelvic region, hips, and legs.

Abnormalities or diseases affecting the bifurcation of the aorta can lead to serious health complications, such as abdominal aortic aneurysm, a condition where the walls of the aorta weaken and bulge, putting the artery at risk of rupturing. Treatment options for such conditions may include medication, surgery, or endovascular repair.
