The Celiac Trunk: Anatomical Variants and Malformations - A Narrative Review
Chirurgia (Bucharest, Romania : 1990)
|July 10, 2025
Summary
The celiac trunk (CT), a vital artery supplying foregut organs, shows significant anatomical variation beyond the typical trifurcation. Understanding these celiac trunk anomalies is crucial for safe surgical and radiological interventions.
Area of Science:
- Anatomy
- Vascular Biology
- Embryology
Background:
- The celiac trunk (CT) is the primary arterial supply for foregut-derived organs.
- The typical branching pattern is a trifurcation (Tripus Halleri).
- Significant anatomical variability exists in CT origin, branching, and structure.
Purpose of the Study:
- To review the embryological basis of CT variations.
- To explore the physiological anatomy and classifications of CT anomalies.
- To discuss the clinical implications of CT variations in medicine.
Main Methods:
- Literature review of anatomical and clinical studies.
- Synthesis of data from cadaveric, radiological, and clinical research.
- Analysis of historical and contemporary CT classification systems.
Main Results:
- Variations include bifurcation, tetrafurcation, and heptafurcation of the CT.
- CT anomalies have implications for hepatobiliary surgery and liver transplantation.
- Morphological variability is influenced by developmental, genetic, and ethnic factors.
Conclusions:
- Thorough anatomical knowledge of CT variations is essential for radiological diagnostics.
- Understanding CT anomalies is critical for effective surgical planning.
- CT variability necessitates individualized approaches in clinical practice.

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.

2.4K
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...

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

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,...

01:24Esophageal Varices-I: Introduction
354
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
