Insights

Arterial corona mortis, a vascular variation, was found in 45% of dissections. Understanding this anatomy is crucial for preventing severe bleeding during pelvic surgeries and managing trauma.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Surgical Anatomy

Background:

  • The arterial corona mortis represents a vascular anastomosis.
  • Variations in pelvic vasculature can pose surgical risks.

Purpose of the Study:

  • To determine the prevalence of arterial corona mortis.
  • To describe its anatomical characteristics and clinical significance.

Main Methods:

  • Dissection of 60 hemipelvises (50 male, 10 female).
  • Measurement of obturator artery and anastomotic branch caliber and length.
  • Statistical analysis using GraphPad Prism 6.

Main Results:

  • Arterial corona mortis was present in 45% of the sample.
  • The obturator artery most commonly originated from the internal iliac artery.
  • Average caliber of the anastomotic branch was 2.7mm and the obturator artery was 2.6mm.

Conclusions:

  • Vascular connections between obturator, iliac, and epigastric arteries are common.
  • Variations in diameter and trajectory of these anastomotic arteries exist.
  • These variations can lead to life-threatening hemorrhage in iatrogenic injuries and fractures.

Gross Anatomy of Bone01:17

Gross Anatomy of Bone

The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Gross Anatomy of Skeletal Muscles

The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...

Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Anatomical Terminology01:20

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

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,...
