Introduction: The right and left common iliac arteries are the two terminal direct branches of abdominal aorta. Similarly internal iliac artery and external iliac artery are the two terminal branches of the common iliac arteries supplying the pelvis and the lower extremities. The present study is an observational analysis of morphometry of Common iliac artery (CIA), internal iliac artery (IIA) and external iliac artery (EIA) in human cadavers. Materials and Methods: Thirty formalin fixed cadavers were dissected in the Department of Anatomy, SMS Medical College, Jaipur. The abdominal aorta, common iliac arteries, internal iliac arteries and external iliac arteries were exposed with fine dissection and their lengths were measured. The statistical analysis was done by excel. Results: The average length of the right common iliac artery was 6.07 cm (± 0.97) and that of the left common iliac artery was 5.53 cm (± 1.18) in males (n=21). In females (n=9) the average length of the right common iliac artery was 4.07 cm (± 0.9) and of the left common iliac artery was 4.44 cm (± 1.13). The average lengths of right and left internal iliac arteries in males were 3.65 cm (± 0.96) and 4.14 cm (± 1.0) respectively. Similarly, the average lengths of right and left internal iliac arteries in females were 4.33 cm (± 0.78) and 4.6 cm (± 2.49) respectively. The average lengths of right external iliac arteries in male and female (9.27 cm ± 1.37 and 10.73 cm ± 2.49 respectively) cadavers were more than the average length of left external iliac arteries in both male and female (8.76 cm ± 1.06 and 10.27 cm ± 3.1 respectively) cadavers. No statistical difference was observed in CIA, IIA and EIA lengths between males and females. Conclusions: The knowledge of the morphometric and morphological anatomy of the of major vessels of lower abdomen and pelvis is of great clinical significance. The course, length or branching pattern of these vessels are having their clinical impact based on the prior proper knowledge. The interventional radiologists and vascular surgeons should be aware of this knowledge.
