title: Corona mortis anastomosis: a three-dimensional computerized tomographic angiographic study.
abstract: OBJECTIVE
  We evaluated the corona mortis (CM) anatomy by means of three-dimensional computerized tomography angiographic (CTA).
  
  
  METHODS
  Patient demographic, anastomosis incidence, artery diameter, artery distance from the symphysis pubis, and pelvic size (distance between both acetabular upper labrum) parameters were assessed. The 100 patients included 66 males and 34 females (average age of 67.8 years).
  
  
  RESULTS
  There were 66 (33%) arterial anastomoses in the 200 evaluated arteries, 30 in the right side and 36 in the left side, 36 unilaterally and 15 bilaterally. No anastomoses were detected in 49 patients. The average diameter was 2.4 mm for the right-sided arteries and 2.24 in the left-sided ones. The distance was 55.2 mm from the right symphysis and 57.2 from the left symphysis (greater for females, 62.2 versus 55.85 mm [p = 0.037] only on the left side). The artery disappears in smaller-sized pelvises. There was a non-occluded arterial pattern in 47 (71%) and a partially occluded one in 19 (29%, all with peripheral vascular disease).
  
  
  CONCLUSIONS
  One-third of the evaluated CTAs revealed competent CMs. CMs were more lateral in females than in males and were absent in small-sized pelvises. It is highly recommended that the radiologist and the surgeon should be familiar with CM existence for decision-making with regard to emergency radiology imaging and intervention as well as when operating in proximity of that anatomic site.
