Insights

This study analyzed celiac trunk (CeT) and hepatic artery (HA) variations using CT angiography. Understanding these anatomical branching patterns is crucial for preventing surgical complications.

Area of Science:

  • Radiology
  • Vascular Anatomy
  • Medical Imaging

Background:

  • Anatomical variations in the celiac trunk (CeT) and hepatic artery (HA) can complicate surgical and radiological procedures.
  • Accurate classification and understanding of these variations are essential for patient safety.

Purpose of the Study:

  • To analyze the distribution of anatomical variations in celiac trunk (CeT) and hepatic artery (HA) branching patterns.
  • To propose a unified classification system for CeT and HA vascular anatomy.

Main Methods:

  • Observational study utilizing CT angiography.
  • Evaluation of CeT and HA branching patterns in 340 patients.
  • Classification of variations into five types and ten subtypes, analyzed by age and gender.

Main Results:

  • The classic branching pattern (Type 1) was observed in 70.6% of cases.
  • Variations in HA branching (Type 2) occurred in 19.12%, and anomalous CeT variants (Types 3-5) in 11.17%.
  • No significant differences in variation frequency were found based on gender or age.

Conclusions:

  • Awareness of CeT and HA anatomical variations, particularly concurrent variations, is vital for surgical and radiological planning.
  • Understanding these patterns helps prevent iatrogenic injuries and complications.
  • A unified classification aids in consistent reporting and interpretation of vascular anatomy.

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...

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,...

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

The Arch of Aorta01:10

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

The Aorta01:14

The Aorta

The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
