Introduction: Corona Mortis (CMOR) is a term used to
describe an anatomical vascular variant of retropubic
anastomosis located posterior to superior pubic ramus. We
aim to provide sufficient data on the incidence, morphology
and mean location of ‘crown of death’ in Asian population.
Other objectives include to assess the relationship between
CMOR incidence with gender, race and age.
Materials and methods: This is a cross-sectional cadaveric
study involving 164 randomly selected fresh multiracial
Asian hemipelves (82 cadavers). Hemipelves were dissected
to expose and evaluate the vascular elements posterior to
superior pubic rami. Data were analysed using Chi-Square, ttest and with the help of IBM SPSS Statistics v26 software.
Results: CMOR was found in 117 hemipelves (71.3%). No
new morphological subtype was found. The mean distance of
CMOR to symphysis pubis was 54.72mm (SD 9.35). Based
on the results, it is evident that precaution needed to be taken
at least within 55mm from symphysis pubis during any
surgical intervention. The lack of statistically significant
correlation between CMOR occurrence and gender, race and
age suggest that the incidence of CMOR could be sporadic in
manner.
Conclusion: We conclude that CMOR is not just aberrant
vessel as the incidence is high and this finding is comparable
to other studies. The mean location of CMOR obtained in
this study will guide surgeons from various disciplines in
Asia to manage traumatic vascular injury and to perform a
safe surgical procedure involving the pelvis area.
