Insights

The corona mortis, a common pelvic vascular variant, involves vessels crossing the pubic ramus, posing a significant bleeding risk during trauma or surgery. Awareness and reporting of this anatomy are crucial for patient safety.

Area of Science:

  • Anatomy
  • Vascular Anatomy
  • Pelvic Anatomy

Background:

  • The corona mortis is a frequent anatomical variation in the pelvis.
  • It involves arterial or venous vessels crossing the superior pubic ramus.
  • This course makes the vessels vulnerable to injury in pelvic trauma and surgery.

Purpose of the Study:

  • To review the anatomy of the arterial corona mortis.
  • To illustrate its clinical significance using imaging examples.
  • To emphasize its importance as a leading pelvic vascular variant.

Main Methods:

  • Computed tomography angiography (CTA).
  • Digital subtraction angiography.
  • Review of anatomical variations and clinical scenarios.

Main Results:

  • The arterial corona mortis is a prevalent pelvic vascular variant.
  • Its anatomical course presents a high risk of hemorrhage.
  • Radiologists must recognize and report this variant when clinically relevant.

Conclusions:

  • The arterial corona mortis is a clinically significant pelvic vascular variant.
  • Familiarity with its anatomy and associated hemorrhagic risk is essential for radiologists.
  • Explicitly reporting the corona mortis in radiological findings can improve patient care.

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Thoracic Aorta01:15

Thoracic Aorta

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
Uterus and Cervix01:18

Uterus and Cervix

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...
Anatomy of Blood Vessels01:20

Anatomy of Blood Vessels

The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...
Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...
Veins of Thorax01:19

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
The...
