BACKGROUND: “Corona mortis” is an abnormal arterial or venous connection between the obturator and the inferior epigastric or external iliac arteries or veins, which can cause torrential bleeding leading to the death of the individual. It may be encountered during acetabular surgeries, hernia surgeries, and gynecological procedures. The purpose of our study is to determine the incidence and variations of corona mortis in the south Indian population. MATERIALS AND METHODS: Forty hemipelves of 20 cadavers were in our study group. With the cadaver in the supine position, dissection was done using Stoppa’s approach. After dissection, data about the presence or absence of corona mortis, the nature of corona mortis (arterial/venous/arteriovenous variant), and the distance between corona mortis and pubic symphysis were collected. RESULTS: Corona mortis was present in 33 (82.5%) hemipelves. It was bilateral in 13 (65%) cadavers. It was present in all the female cadavers on both sides, whereas it was present in 21 (75%) out of the 28 male hemipelves. Venous variant was present in 26 (78.78%), followed by arteriovenous variant in five (15.16%), and arterial variant in two (6.06%) hemipelves. The mean distance of corona mortis from pubic symphysis was 55.65 mm. CONCLUSIONS: The incidence of corona mortis was 82.5% in our study. Our study was dominated by the venous variant compared with the arterial and arteriovenous variants. Corona mortis had gender variations: it was present in all the females in our study, whereas it was not so among males as per our study.
