Crucial anatomy and technical cues for laparoscopic transabdominal preperitoneal repair: Advanced manipulation for groin hernias in adults

Figure 9 Corona mortis. Corona mortis and complicated vascular connection between the epigastric and obturator vessels. The corona mortis is classically defined as the arterial anastomosis between the obturator artery and the inferior epigastric artery via the ectopic obturator artery. The existence of the obturator artery results in annular communication between the inferior epigastric artery, common iliac artery, internal iliac artery, external iliac artery, and obturator artery. There may be several variants of anastomosing vascular branches. Brisk bleeding is difficult to control because of the dual vascular supply from the obturator and iliac vessels.
