UTERINE ARTERY

 

 

ORIGIN: Anterior division of the internal iliac artery.

 

COURSE/DISTRIBUTION: Springs from the anterior division of the internal iliac artery as a branch that supplies the uterus. It is therefore the equivalent of the inferior vesical artery in the female. It runs below the obturator artery and above and anterior to the internal pudendal and middle rectal arteries. It runs initially on the levator ani to approach the cervix. 2cm to this organ it passes just lateral to lateral fornix of vagina and is crossed at right angles by the ureter, which it supplies. It then turns at a right angle to ascend in the broad ligament of the uterus close to the cervix and uterine body. At the uterotubal junction, it runs in the mesosalpinx where it anastomoses with the ovarian artery. The uterine branches are two anterior and posterior arcuate arteries which run on the corresponding positions into the uterine substance from where tortuous helicine arteries take their origin and form arterioles (including spiral arterioles), that supply the endometrium.

 

BRANCHES:

  • Anterior arcuate arteries to the uterus
  • Posterior arcuate arteries to the uterus
  • Vaginal branches which anastomose with the branches of vaginal artery
  • Cervical arteries
  • Ureteric branch.
  • Vaginal artery (sometimes).

 

BRANCHES:

  • Rectal branches.

 


UVTO longitudinal anasotomes running from ovarian artery superiorly through the uterine artery, vaginal artery and the azygos artery of the vagina in the perineum, and then with the anastomosis from the perineal branch of internal pudendal artery. It joins the systemic circulation superiorly through the ovarian artery and abdominal aorta ,and inferiorly through the perineal branch of the internal pudendal artery. Check UTVO circulation
