Summary
The corona mortis (CM) anatomy, or vascular connection between the obturator artery and femoral artery, is present in one-third of individuals. This vascular anatomy is more lateral in females and absent in smaller pelvises.
Area of Science:
- Anatomy
- Vascular Surgery
- Radiology
Background:
- The corona mortis (CM) is an important vascular structure in the pelvic region.
- Understanding its anatomy is crucial for surgical procedures and emergency interventions.
Purpose of the Study:
- To evaluate the anatomy of the corona mortis (CM) using three-dimensional computerized tomography angiography (CTA).
Main Methods:
- 100 patients (66 males, 34 females; average age 67.8 years) underwent CTA.
- Parameters assessed included anastomosis incidence, artery diameter, distance from the symphysis pubis, and pelvic size.
Main Results:
- 66 (33%) arterial anastomoses were found in 200 arteries.
- Average diameters were 2.4 mm (right) and 2.24 mm (left).
- CMs were more lateral in females and absent in smaller pelvises.
Conclusions:
- One-third of CTAs revealed competent CMs.
- Awareness of CM anatomy is vital for surgeons and radiologists for safe decision-making.
- CMs can be absent in patients with smaller pelvic dimensions.
