Arterial System

Branches of Internal Iliac Artery

I Love Going Places In My Very Own Underwear”:

  • Ileolumbar
  • Lateral sacral
  • Gluteal (superior and inferior)
  • Pudendal (internal)
  • Inferior vesicle (uterine in females)
  • Middle rectal
  • Vaginal
  • Obturator
  • Umbilical

Coelic trunk: branches

  • Left Hand Side (LHS):
  • Left gastric artery
  • Hepatic artery
  • Splenic artery

Descending abdominal aorta branches from diaphragm to iliacs

Prostitutes Cause Sagging Swollen Red Testicles [in men] Living In Sin”:

  • Phrenic [inferior]
  • Celiac
  • Superior mesenteric
  • Suprarenal [middle]
  • Renal
  • Testicular [“in men” only]
  • Lumbars
  • Inferior mesenteric
  • Sacral

Descending abdominal aorta: seven divisions

Sometimes Intestines Get Really Stretched Causing Leakage”:

  • Suprarenals [paired]
  • Inferior mesenteric
  • Gonadal [paired]
  • Renals [paired]
  • Superior mesenteric
  • Celiac
  • Lumbar [paired]

Female pelvic organs’ blood supply

3 organs, each get 2 blood supplies”:

Uterus: uterine, vaginal.

Rectum: middle rectal, inferior rectal [inferior rectal is the end of pudendal].

Bladder: superior vesical, inferior vesical.

Femoral artery deep branches

Put My Leg Down Please”:

  • Profundus femoris (deep femoral artery)
  • Medial circumflex femoral artery
  • Lateral circumflex femoral artery
  • Descending genicular arteries
  • Perforating arteries

Inferior vena cava tributaries

I Like To Rise So High”:

  • Illiacs
  • Lumbar
  • Testicular
  • Renal
  • Suprarenal
  • Hepatic vein.

Think of the IVC wanting to rise high up to the heart.

Internal iliac artery: anterior branches

What Bill admitted to Hilary: “IMilked Our Insatiable Intern’s Udders Under the Desk”:

  • Inferior gluteal
  • Middle rectal
  • Obturator
  • Inferior vesical artery
  • Internal pudendal artery
  • Umbilical
  • U/D=Uterine artery (female)/ Deferential artery (male)

Internal iliac artery: posterior branch

PILS:

  • Posterior branch
  • Iliolumbar
  • Lateral sacral
  • Superior gluteal

Portal-systemic anastomoses: main 2 places that retroperitoneals connect into systemic

RetroPeritoneals hook up with Renal and Paravertebral veins.

Ureter to ovarian/testicular artery relation

Water under the bridge”:

The ureters (which carry water), are posterior to the ovarian/testicular artery.

Clinically important, since a common surgical error is to cut ureter instead of ovarian artery when removing uterus.

Internal pudendal branches

I Pee Pee But Don’t Dump!”:

  • Inferior rectal
  • Posterior scrotal (or labial)
  • Perineal
  • Bulb
  • Deep artery
  • Dorsal artery

 You can suggest more mnemonics …
