“Crown of Death”; Corona Mortis, a Common Vascular Variant in Pelvis

The corona mortis, literally meaning “crown of death,” is a critical vascular variant that every laparoscopic hernia surgeon must recognize and respect. This arterial or venous connection between the external iliac or inferior epigastric system and the obturator vessels courses over the superior pubic ramus, precisely in the operative field during laparoscopic inguinal hernia repair. In both Transabdominal Preperitoneal Repair (TAPP) and Totally Extraperitoneal Repair (TEP), dissection of the preperitoneal space and mesh fixation near Cooper’s ligament places this vessel at particular risk. Unrecognized injury to the corona mortis can result in sudden, profuse hemorrhage that is difficult to control laparoscopically due to vessel retraction behind the pubic bone. Therefore, careful and gentle dissection in the retropubic (Retzius) space is mandatory, with clear identification of vascular structures before clip application or tack fixation. Surgeons should avoid blind stapling or tacking below the iliopubic tract and maintain strict awareness of the so-called “triangle of doom” and adjacent danger zones. If bleeding occurs, prompt compression, precise bipolar coagulation, or secure clipping is essential to prevent hemodynamic instability. Ultimately, systematic anatomical orientation and respect for this vascular variant significantly enhance safety and reduce potentially life-threatening complications in laparoscopic hernia repair.
