Abstract
Anatomical variations of the obturator artery in a group of Sri Lankan subjects: A cadaveric study
Highlights
The aberrant obturator artery (AOA) which crosses the superior pubic ramus is at risk of damage in pelvic trauma and surgeries
The normal pattern of the OA originating from the anterior division of internal iliac artery (IIA) was found in 17 (56.6%) hemipelvises
Out of all the hemipelvises 7(23.3%) OAs originated from the inferior epigastric artery (IEA) while 4(13.3%) OAs originated from the posterior division of IIA
Summary
Samarawickrama MB1*, Rodrigo PM1, Nanayakkara PGCL1, Chamara AGD1, Tharaka NGS1, Karunadasa THAS1. The aberrant obturator artery (AOA) which crosses the superior pubic ramus is at risk of damage in pelvic trauma and surgeries. The knowledge of its common variations and incidence are important in clinical practice.
