| Popis: | Purpose: Corona mortis is an abnormal arterial or venous anastomosis between the external iliac and the obturator system of vessels and may cause significant hemorrhage during pelvi-acetabular fracture surgeries, hernia repair and laparoscopic gynecological procedures. Previous studies have estimated a prevalence of corona mortis between 34% and 70%. This cadaveric study was conducted to estimate the prevalence of corona mortis in the North Indian population. Materials and Methods: Twelve cadavers (24 hemipelvises; 11 males and 1 female) with a mean age of 68 (range, 54-82) years were included in this study. Results: Corona mortis was observed in 14 hemipelvises (58.3%). A total of 19 (79.2%) vascular anastomoses of diameter greater than 1 mm were observed; 5 hemipelvises (20.8%) had corona mortis on the right side, 9 hemipelvises (37.5%) on the left side and bilateral in 5 (41.7%) cases. Two hemipelvises (8.3%) had an arterial connection. An aberrant obturator artery was observed in 1 (4.2%) hemipelvis. A venous connection was found in 14 specimens (58.3% of hemipelvises). The average distance of the connecting vein from the symphysis pubis was 41 (35-70) mm. A vessel diameter of greater than 4 mm was observed in 4/24 (16.7%) of hemipelvises. Conclusion: The frequency of venous corona mortis was higher than arterial corona mortis and the majority (83.3%) were small calibre ( |
