Fascinating history of groin hernias: Comprehensive recognition of anatomy, classic considerations for herniorrhaphy, and current controversies in hernioplasty

Figure 12  Corona mortis. The corona mortis is classically defined as the arterial anastomosis between the obturator and the inferior epigastric arteries by means of the ectopic obturator artery. The existence of the obturator artery results in annular communication among the inferior epigastric, common iliac, internal iliac, external iliac, and obturator arteries. Brisk bleeding is difficult to control because of the dual vascular supply from the obturator and iliac vessels.
