At which vertebral level does the abdominal aorta bifurcate?

The abdominal aorta typically bifurcates into the common iliac arteries at the level of the fourth lumbar vertebra, which is L4. This bifurcation occurs as the aorta descends through the abdomen and approaches the pelvis.

Understanding the anatomical landmarks is important in both clinical and surgical settings, as knowing the precise locations of major vessels can aid in diagnosis and interventions. The bifurcation at L4 allows for the proper distribution of blood to the lower extremities and pelvic organs. This knowledge is vital for healthcare professionals when considering vascular surgery, trauma assessment, and imaging interpretation.
