| Abstract | Corona mortis (CM) is an anastomotic vessel that crosses behind the superior pubic ramus. The presence of the anastomoses is not persistent and has many variations of patterns, and locations. The aim of this study was to provide prevalence and the anatomical details of CM. This study was performed on fresh cadavers. The number and patterns of CM were recorded, consisting of the lengths, diameters, and distances, which were measured from anatomical landmarks of interest. Sixty-eight hemipelvises were studied. The CM were found in 24 (35.29%) hemipelvises. The arterial corona mortis (ACM) presented in 10 hemipelvises. Seven ACM were the anastomoses between the external iliac artery (EIA) and the obturator artery (OA), 4 were OA, which originated from EIA or the inferior epigastric artery (IEA). The venous corona mortis (VCM) was found in 13 (19.12%) hemipelvis. Eleven VCM were anastomoses between external iliac vein (EIV) and obturator vein (OV), 3 were OV drained to EIV or inferior epigastric vein (IEV), and in 4 (5.8%), the hemipelvises had multiple CM. The mean diameters, lengths, and distances from the symphysis of CM were 2.98, 33, and 45 mm, respectively. In this study, the Prevalence of CM was 35.29%. Twenty-eight percent of CM were aberrant obturator vessels, which originated from external iliac system. Six percent of hemipelvis had 2 or more anastomoses. During surgery, great care should be taken to identify all vessels traversing behind the superior pubic ramus in the retropubic space in order to prevent catastrophic hemorrhage. |
