106. Common iliac artery. External iliac artery. Femoral artery

Covers the common iliac artery's origin at the bifurcation of the abdominal aorta and its division into internal and external branches, then the external iliac artery and its branches before it passes under the inguinal ligament, including the anastomosis forming the Crown of Death. Ends with the femoral artery's course through the inguinal canal, femoral triangle and adductor canal, listing its superficial and deep branches, and the femoral triangle itself.

  1. COMMON ILIAC ARTERY
  2. EXTERNAL ILIAC ARTERY
  3. FEMORAL ARTERY
  4. Femoral triangle:

COMMON ILIAC ARTERY

  • Arise from the abdominal aorta bifurcation at the L4 level.
  • They are left & Right common iliac artery. each divide into their terminal branches:

Abdominal aorta

  • L4
  • Right common iliac artery. → 1 cm longer than the left.
  • medial aspect of psoas major muscle → between L5-S1 ←
  • External
  • Internal.
  • Left common iliac artery
  • External
  • Internal.

EXTERNAL ILIAC ARTERY

  • Larger than the Internal iliac artery.
  • Course: Inguinal canal (vascular space) → Become Femoral Artery.
  • O: Abdominal aorta →L4 Common iliac artery →Sacroiliac joint R/L External iliac artery.
  • Before passes under the inguinal ligament it gives branches:

EIA

  • Deep Circumflex artery
  • from distal end of EIA.
  • S: Abdomin muscles of the anterior muscles of the pelvic girdle.
  • Inferior epigastric artery
  • Connect Sup. epigastric art. (a branch of internal thoracic art.)
  • * Pubic branch
  • Make anastomosis with the pubic branch of the obturator artery (branch of internal iliac artery).
  • They form the Crown of Death
  • In males: Cremasteric
  • S: the testis
  • In Females: art. of rounded ligament
