Objectives: The aim of this study is to determine the topographic position of the corona mortis on fresh cadavers and also to determine anatomical landmarks that will facilitate surgeons to consider to this structure during operations by clarifying the relationship of the corona mortis with the surrounding anatomical structures. Methods: A total of 50 autopsy cases of 31 men and 19 women, all examined within 24 hours post-mortem, were evaluated bilaterally for the presence of corona mortis. When identified, the vascular characteristics (arterial/venous) of the corona mortis were documented. The topographic position of the corona mortis was determined by measuring the distances to the pubic symphysis, promontory, obturator nerve and anterior superior iliac spine. The study also investigated whether some anthropometric measurements affect these distances. Results: Out of the 100 hemipelves examined, corona mortis were observed in 50 cases. Among these, 34% were arterial (n=17), and 66% were venous (n=33). Anastomoses were identified in the hemipelves of 22 women and 28 men, with no significant gender difference (p>0.05). The average distances to anatomical landmarks were as follows: 5.43 cm to the pubic symphysis, 1.77 cm to the obturator nerve, 9.87 cm to the promontory, and 10.56 cm to the anterior superior iliac spine. Conclusion: Corona mortis poses a significant risk in surgical procedures. Knowing the vascular anatomy of the pelvis is vital for gynecological, urological and orthopedic interventions, while investigating deaths caused by pelvic trauma is important for forensic practice. This anatomical study contributes to a better understanding of the complex and intricate pelvic structure.
