The aorta is one of the retroperitoneal structures, and at the level of L4 it divides into the left and right common iliac arteries, each of which then divide into the Left and right iliac arteries.
When does this arterial "tour" stop being retroperitoneal?
I just wondered that after answering to a Uworld question that says that "arterial puncture above the inguinal ligament increases the risk of retroperitoneal hemorrhage, as the area is directly over the retroperitoneal space".
Note: remember that above the inguinal ligament level the artery is called external iliac artery and below the ligament it is the common femoral artery
