Background: The corona mortis is defined as the vascular connections between the obturator and external iliac systems. These small vessels anastomose behind the pubic symphysis between the obturator and external iliac arteries and have been described in classic anatomy texts. This article reviewed the literature in relation to incidence, anatomy and clinical relevance of the corona mortis. Methods: A systematic search was performed using MEDLINE, EMBASE and CINAHL. Both cadaveric and clinical studies were included. The review identified 38 articles published between 1968 and 2015. Studies were analyzed with narrative data synthesis. Results: There was potential discrepancy between anatomic cadaveric studies and clinical studies in terms of incidence and location. The present study reviewed the relevant literature and provides a comprehensive outline of the anatomy and clinical importance of the corona mortis vessels. We identified reports of both arterial and venous ‘corona mortis’ with a preponderance for venous vessels. Conclusions: There is paucity in the report of adverse events in relation to the corona mortis. Nevertheless, special attention needs to be paid to these vascular anastomoses in the context of pelvic trauma, pelvic surgery, lower abdominal wall hernia as well as laparoscopic procedures.
