Anatomical description of the lumbar branch of the iliolumbar artery
Lumbar branch of iliolumbar artery[edit]
The lumbar branch of the iliolumbar artery is a significant blood vessel that supplies the iliac fossa and the psoas major muscle. It is a branch of the iliolumbar artery, which itself is a branch of the internal iliac artery.
Anatomy[edit]
The lumbar branch of the iliolumbar artery arises from the iliolumbar artery shortly after it branches from the internal iliac artery. It travels laterally and superiorly, passing behind the psoas major muscle. The artery supplies blood to the iliacus muscle and the quadratus lumborum muscle, as well as contributing to the blood supply of the vertebral column.
Function[edit]
The primary function of the lumbar branch of the iliolumbar artery is to provide oxygenated blood to the muscles and structures in the lumbar region. This includes the iliacus, psoas major, and quadratus lumborum muscles, which are important for movements of the hip and stabilization of the lumbar spine.
Clinical significance[edit]
In surgical procedures involving the pelvis or lumbar spine, the lumbar branch of the iliolumbar artery may be at risk of injury. Understanding its course is important for surgeons to avoid inadvertent damage, which could lead to bleeding or compromised blood supply to the lumbar muscles.
