“Corona mortis” means “crown of death”. During routine dissection of an82-year-old male cadaver with no
medical history, we observed an abnormal obturator artery arising from the inferior epigastric artery. The obturator artery
is usually described as a branch of the anterior division of the internal iliac, although this variant has been reported only in
25% of cases.It is considered aberrant when it originates from the inferior epigastric artery and is closely related to
Gimbernat’s ligament. The aberrant obturatorartery crosses medial to, lateral to, or directly over the femoral ring and over
Cooper's ligament. Infrequently, both an aberrant and a normal obturator artery are present, with rich anastomoses at the
obturator canal. Such a vascular arrangement is also called the "circle of death" because of the profuse bleeding that can
occur when either vessel is severed.

Key words: Obturator vessels, inferior epigastric artery,anatomical variation,complications
