Advanced Uterine Artery Quiz

Q1. Why is the uterine artery at risk during hysterectomy?

• Its close relationship to the ureter near the cervix
• It lies inside the urinary bladder lumen
• It passes through the femoral nerve
• It travels within the ovarian follicle

Q2. What is the significance of the uterine artery and ovarian artery anastomosis?

• It forms the main blood supply of the rectum
• It connects internal iliac and ovarian arterial territories
• It supplies the lower limb through the femoral artery
• It connects the portal and systemic venous systems

Q3. Which uterine arterial branches are transformed during normal placentation?

• Straight endometrial arteries only
• Inferior gluteal arteries
• Spiral arteries
• Obturator arteries

Q4. What is the functional purpose of spiral artery remodeling in pregnancy?

• To stop uterine perfusion
• To divert blood exclusively to the ovary
• To convert arteries into lymphatic vessels
• To create low resistance maternal blood flow to the placenta

Q5. Why can uterine artery embolization reduce bleeding from uterine leiomyomas?

• It reduces arterial perfusion to fibroid tissue
• It blocks the external iliac artery
• It removes the endometrium surgically
• It increases venous pressure in the kidney

Q6. Which feature helps the uterine circulation accommodate pregnancy?

• Conversion of uterine arteries into veins
• Loss of all ovarian arterial connections
• Complete postconception obliteration of the uterine arteries
• Marked enlargement and increased uterine arterial flow

Q7. What is the relationship of the uterine artery to the cardinal ligament?

• It courses within the cardinal ligament region toward the cervix
• It lies within the sacrospinous ligament
• It runs through the round ligament to the labium majus
• It passes through the suspensory ligament of the ovary from the aorta

Q8. Why can pelvic arterial anastomoses preserve some uterine perfusion after uterine artery occlusion?

• The uterus has no arterial anastomoses
• Collateral connections provide alternate arterial routes
• Venous valves pump arterial blood into the uterus
• The ureters replace the arterial supply

Q9. Which anatomical relationship is especially important when clamping the uterine artery near the cervix?

• The sciatic nerve lies within the uterine artery
• The ovarian follicle lies below the artery
• The ureter lies inferior to the uterine artery
• The femoral vein lies between the artery and cervix

Q10. Which statement best integrates uterine artery anatomy?

• An external iliac branch passing through the inguinal canal to the uterus
• An internal iliac branch crossing above the ureter and supplying the uterus through extensive arterial networks
• An aortic branch supplying only the ovary
• A venous channel connecting the uterus to the portal system
