Where does blood go after the internal iliac artery?
Where does blood go after the internal iliac artery?

What organs does the internal iliac artery drain?
The internal iliac vein drains the blood from the pelvic organs and pelvic wall, perineum and external genitalia, gluteal region and medial region of the thigh.

Is internal iliac artery retroperitoneal?
Abdominal aorta The ovarian artery, median sacral artery, external iliac artery, internal iliac artery and its branches are important structures of pelvic retroperitoneal vasculature (Figure 5).
What are the risks of bilateral ligation of the iliac artery?
It is for this reason that other workers have advocated bilateral ligation of the internal iliac arteries to significantly improve the chances of reducing pelvic pulse pressure and facilitate hemostasis5. Reported complications include nerve injury, inadvertent ligature of the common iliac artery, prolonged blood loss and prolonged operative time.
What are the side effects of hypogastric artery ligation?
Specific complications of hypogastric artery ligation may include the following: Infertility and impotence in men. Buttock and thigh claudication. Damage to the ureter. Ischemic limb from damage to common or external iliac artery. Damage to other pelvic vessels. Damage to pelvic nerves, including the hypogastric plexus. Spinal ischemia.
What is the prevalence of internal iliac artery aneurysms?
Internal iliac artery aneurysms (IIAA) are a rare condition. Its prevalence is estimated as 0.03%[1], representing 0.3% of all aortoiliac aneurysms and less than 20% of all isolated iliac artery aneurysms[2].
What are the two branches of the iliac artery?
The common iliac artery bifurcates into two main branches – the external iliac artery (which becomes the femoral artery at the inguinal ligament) and the internal iliac (hypogastric) artery which descends into the true pelvis.
