Corona mortis: incidence and location.

The right hemipelvis of 98 patients was examined by angiography to determine the occurrence and location of the corona mortis artery. This arterial anastomosis was found in 28.5% (28 of 98). Its incidence was 30.5% (18 of 59) in men and 25.6% (10 of 39) in women; this difference was not significant ( p>0.05). The distance from the symphysis pubis to the anastomotic artery averaged 33.4 mm (range 21.4-41 mm). It was 31.8 mm (range 21.4-39.3 mm) in men and 36.2 mm (range 25-41 mm) in women; this difference was significant ( p<0.05).
