Purpose
To study the anatomical variations in origin of the internal iliac artery branches in females
using 3 Tesla contrast enhanced Magnetic resonance angiography before uterine artery
embolization.
Methods and Materials
The current study was retrospectively performed.
•
Pre-embolization (before uterine artery embolization) contrast enhanced
magnetic resonance angiography studies from 22 females (Age range 30-53
years) were included in the current study.
•
All evalautions were performed by two radiologists in consensus.
•
A 3 Tesla magnetic resonance imaging unit was used & three dimensional
images Fig. 1 on page 2 were reconstructed using Syngo Vessel View
Application.
•
For each branch the percentage of each point of origin was documented.
•
The evalauted branches Fig. 2 on page 3 were:
1. The uterine artery
2. The superior vesical artery
3. The middle rectal artery
4. The obturator artery
5. The pudendal artery
6. The inferior gluteal artery
7. The superior gluteal artery
8. The lateral sacral artery
9. The iliolumbar artery

Results
Of the studied 44 arteries:
•
•
•
•
•
•
•
•
•
The uterine artery was seen in 44, originating from the anterior division Fig.
3 on page 7 in 29 (65%), the main stem in 2 (5%), the bifurcation point
in 6 (14%) & indirectly from the anterior division by a common trunk with
other arteries in 7 (16%).
The superior gluteal artery was seen in all patients and always originated
from the posterior division (100%)
The inferior gluteal artery was also seen in all patients and originated from
the anterior division in 35 (80%) & from the posterior division in 9 (20%).
The lateral sacral artery seen in 44 originated from the posterior division in
34 (77%), the main stem in 6 (14%), the bifurcation point in 3 (7%), & from
the inferior gluteal artery in 1 (2%).
The iliolumbar artery seen in 43 originated from the main stem in 19 (44%),
the posterior division in 11 (26%) & from the bifurcation point in 13 (30%).
The superior vesical artery seen in 21 originated from the anterior division in
20 (95%) and by a common segment with the internal pudendal in 1 (5%).
The middle rectal seen in 12 arteries originated from the anterior division in
all of them (100%).
The internal pudendal artery seen in 44 originated from the anterior division
in 42(95%), indirectly from the anterior division in 1 (2.5%) and from the
bifurcation point in 1 (2.5%).
The obturator artery seen in 42 originated from the anterior division in 18
(43%), from the inferior epigastric artery in 11 (26%), the posterior division in
5 (12%), bifurcation point in 1 (2%) & indirectly from the anterior division in 7
(17%).

Conclusion
•
The internal iliac artery shows a wide range of origin of its different branches
in females.
•
Knowing these variations of origin are of utmost importance before
performing pelvic interventional procedures in females e.g uterine artery
embolization.
