PurposeCorona 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 MethodsTwelve cadavers (24 hemipelvises; 11 males and 1 female) with a mean age of 68 (range, 54–82) years were included in this study.ResultsCorona 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.ConclusionThe frequency of venous corona mortis was higher than arterial corona mortis and the majority (83.3%) were small calibre (<4 mm). The presentation pattern and the number of arterial or venous anastomoses were different in the majority of hemipelvises and dissimilar in both hemipelvises of the same cadaver in the majority of cases.

Variations of the testicular vessels were observed during routine dissection of the posterior abdominal wall in a male North Indian cadaver. On the right side, the testicular vein drained into the right renal vein and the right testicular artery passed posterior to the inferior vena cava. The left testicular vein was composed of the lateral and medial testicular veins which drained into the left renal vein independently. Left renal vein had received an additional tributary, first lumbar vein, and the left testicular artery had hooked this additional tributary to run along its normal course.
