Why is it called corona mortis?

The name “corona mortis” or crown of death testifies to the importance of this feature, as significant hemorrhage may occur if accidentally cut and it is difficult to achieve subsequent hemostasis. It constitutes a hazard for orthopedic surgeons especially in the anterior approach to the acetabulum.

Does everyone have corona mortis?

The incidence of venous corona mortis is between 27% (1) and 100% (2). On the other hand, the incidence of arterial corona mortis is between 14.8% (3) and 36% (4). The corona mortis may have several anatomic variations.

What means corona mortis?

Corona mortis, Latin for “crown of death”, is a common variant vascular anastomosis between the external iliac artery or deep inferior epigastric artery and the obturator artery.

What muscles does the obturator artery supply?

The obturator artery supplies the pelvic muscles it crosses, the head of the femur, the muscles of the medial compartment of the thigh and gives a small branch to the knee capsule. The iliac branch supplies the bone and the iliacus muscle. It also has a cutaneous supply to the medial thigh.

What is internal iliac artery?

The internal iliac arteries (IIA) supply the majority of the pelvis and the structures within, and the external iliac artery continues down to supply the lower extremities. The arteries within the pelvis can have numerous variations and these become important during surgery within the pelvis.

Where is the femoral artery?

thigh
Where is the femoral artery located? The location of the femoral artery is at the top of your thigh in an area called the femoral triangle. The triangle is just below your groin, which is the crease where your abdomen ends and your legs begin. The femoral artery runs to the lower thigh and ends behind the knee.

Is the femoral artery deep?

The deep artery of the thigh, (profunda femoris artery or deep femoral artery) is a large branch of the femoral artery. It travels more deeply (posteriorly) than the rest of the femoral artery.

When does external iliac become common femoral?

The exit point of the external iliac arteries is lateral to the insertion point of the inguinal ligament on the pubic tubercle, approximately one-third the distance from the pubic tubercle to the anterior superior iliac spine. Distal to the inguinal ligament, the external iliac artery becomes the common femoral artery.

What comes off the external iliac artery?

The external iliac artery provides the main blood supply to the legs. It passes down along the brim of the pelvis and gives off two large branches – the “inferior epigastric artery” and a “deep circumflex artery.” These vessels supply blood to the muscles and skin in the lower abdominal wall.
