Internal iliac artery (IIA) ligation is one of the emergency methods of postpartum haemorrhage. Understanding the anatomy of the pelvic artery and its related landmarks is very important and essential for the obstetrician and gynecologist. Objective: To study (1) the characteristics of the internal iliac artery, (2) relationship between the internal iliac artery and anatomical landmarks. Methods: Descriptive cross-sectional study is conducted from 10/2019 to 05/2020. 18 left and right internal iliac arteries of 18 cadavers preseved in formalin solution in department of Anatomy, the University of Medicine and Pharmacy at HCM city. Results: Most of the principal IIA is at the level of the lumbar vertebrae 4 - 5. The average distance from the principal of the IIA to the sacral promontory is 33.95 + 3.35 mm (left) and 31.70 + 4.64 mm (right). The always has two big branches, the front and the back branch. A third branch is the iliolumbar artery, which is also a common branch accounting for 43.33%. The diameter of the IIA artery branches is similar between the left and right side, the branches of the same name are usually slightly larger in diameter on the left than the right. Conclusion: The Internal iliac artery is an important artery that supplies blood to the pelvic region and female reproductive organs. IIA always has two large branches, the anterior and posterior branches, in some cases the artery has the third branch, the iliolumbar artery. The length of the IIA from the principal artery to the first lateral branching is similar in both the right and left sides. The distance from the principal of the IIA to the sacral promontory suggests to the surgeon the location of the IIA after determining the sacral promontory during surgery. Anatomical correlation is the ureter crosses the IIA and the uterine artery, the distance as well as the position of the cross is essential in the direction of dertemining the ureter in obstetrics and gynecology.
