Pelvic congestion syndrome — also called pelvic venous insufficiency — is a chronic pain condition associated with blood flow problems in your pelvic veins. “Chronic” means pain lasting longer than 6 months that isn’t associated with either your menstrual cycle or pregnancy.
The arteries of the pelvis are derived from the abdominal aorta, which bifurcates into a left and right common iliac artery on the left hand side of the fourth lumbar vertebra. The common iliac arteries bifurcate at the sacroiliac joint to give off an internal and a larger external iliac artery.
The pelvic cavity contains the organs of reproduction, urinary bladder, pelvic colon, rectum and numerous muscles. Its arterial supply is largely via the internal iliac artery, with some smaller arteries providing additional supply.
The pelvic cavity opens superiorly to, and is continuous with, the abdominal cavity through the pelvic inlet. Whilst the pelvic outlet is enclosed by the pelvic floor, made of the pelvic diaphragm. There are two parts of the pelvis; greater (false) pelvis and lesser (true) pelvis.
Vasculature of the Pelvis. The vasculature within the pelvis can be split into the arteries of the pelvis and venous drainage of the pelvis. The arteries of the pelvis provide oxygenated blood to the organs and tissues of the pelvis and also transmit blood that supplies the lower limbs.
The veins of the pelvis drain deoxygenated blood and return it to the heart. There are three major vessels involved in the venous drainage of the pelvis - the external iliac vein, internal iliac vein and common iliac vein (these correspond the major major pelvic arteries).
The iliac arteries are blood vessels that provide blood to the legs, pelvis, reproductive organs and other organs in the pelvic area. The pelvis is the lower part of your torso, just above where your legs connect at the hips.
In the pelvis, the spinal column ends in the sacrum, five fused vertebral bones that form the back of the pelvis. Behind it is the sacral plexus, a collection of nerves that serve the pelvic...
The abdominal and pelvic vasculature harbors numerous vessels critical in surgical contexts, such as incision-related injuries, ureter damage in pelvic surgeries, and metastatic routes. Lower abdominal wall incisions risk injuring the inferior epigastric artery.
The internal iliac artery (IIA), or hypogastric artery, is the primary artery supplying the pelvic viscera and an important contributor to structures of the pelvic wall, perineum, gluteal region, and thigh.
