ABSTRACT
Background: The deep circumflex iliac artery(DCIA) is a lateral branch of external iliac artery(EIA) arising posterior to the inguinal ligament(IL).DCIA flaps are used extensively in oromandibular reconstruction. This study focusses on the normal and anatomical variations in the origin of the deep circumflex iliac artery.
Material and Methods: Fifty adult lower limb specimens were obtained from the embalmed cadavers at the department of Anatomy, Stanley Medical College,Chennai.The inguinal regions and the corresponding femoral triangles were dissected.The origin of the DCIA in relation to the inguinal ligament was noted.Variations present in the origin of DCIA was identified and studied.
Results: Out of the 50 lower limb specimens,in 32 cases(64%) the DCIA arose laterally from the EIA posterior to the inguinal ligament.In 14 cases(28%) the deep circumflex iliac artery took origin from the femoral artery(FA) below the IL.In 4 specimens(8%) it arose from the EIA above the IL.
Conclusion: There are variations present in the origin of theDCIA.The DCIA flaps are used in mandibular reconstruction procedures and their dissection needs a good anatomical knowledge of the normal and variant origins of the deep circumflex iliac artery
Key words: Deep circumflex iliac artery,External iliac artery,Inguinal ligament,femoral artery.
