External Iliac Artery Dissection

External Iliac Artery Dissection occurs when the wall of the external iliac artery, a blood vessel in the pelvic region, tears or separates. This condition can lead to various complications, making it crucial to understand its causes, symptoms, diagnosis, and treatment options.

The external iliac artery is a vital blood vessel that supplies blood to the lower limbs. Dissection refers to the tearing of the artery wall, which can cause blood to leak into the surrounding layers. This can lead to reduced blood flow and potentially serious complications.

Types:

External Iliac Artery Dissection can be categorized into two main types:

  1. Traumatic Dissection: Resulting from physical injury or trauma to the pelvic region.
  2. Spontaneous Dissection: Occurs without an apparent cause and is often associated with underlying vascular conditions.

Causes of External Iliac Artery Dissection:

  1. Atherosclerosis: Buildup of fatty deposits in the artery walls.
  2. Hypertension: High blood pressure that strains the artery walls.
  3. Genetic Factors: Family history of vascular disorders.
  4. Connective Tissue Disorders: Conditions affecting the tissues supporting blood vessels.
  5. Infection: Arterial inflammation due to infection.
  6. Smoking: Tobacco use can contribute to artery wall damage.
  7. Trauma or Injury: Physical impact leading to artery wall tears.
  8. Pregnancy: Increased pressure on the pelvic vessels.
  9. Aneurysm: Weakening and bulging of the artery wall.
  10. Arteritis: Inflammation of the artery walls.
  11. Coagulation Disorders: Conditions affecting blood clotting.
