Learning objectives Describe the anatomical characteristics and clinical significance of corona mortis (CM). Highlight the importance of recognizing CM as a potential cause of life-threatening hemorrhage in the context of pelvic trauma or surgery.
Read more Background Corona mortis (Latin for “crown of death”) refers to an anatomical variant involving a vessel (in this poster, the arterial variant) from the external iliac artery system that crosses the superior pubic ramus, forming an arterial anastomosis with branches of the internal and external iliac vessels [1, 2]. This vascular variant is significant because injury to CM can result in life-threatening hemorrhage [4, 5], particularly in pelvic trauma and surgeries. Studies have reported an arterial CM prevalence ranging from 26.2%...
Read more Findings and procedure details The arteries that commonly contribute to CM are the obturator artery and the inferior epigastric artery. The obturator artery is a branch of the internal iliac artery, supplies the muscles around the hip joint, and follows a trajectory along the pelvic rim, exiting the pelvis through the obturator canal [4, 5]. [fig 1] [fig 2] The inferior epigastric artery is a branch of the external iliac artery and supplies the rectus sheath [1, 4].The CM typically crosses the superior pubic ramus and may...
Read more Conclusion Corona mortis prevalence is higher than previously thought. Recognizing the existence of CM is essential in preventing acute or delayed life-threatening hemorrhage in trauma and surgical contexts. Careful preoperative and intraoperative vascular mapping, including the use of CTA or DSA, can significantly reduce complications related to CM. When obturator arterial injury is initially suspected at CT due to acetabular or pubic rami fractures and adjacent hemorrhage, external iliac angiography is prudent.
