Summary
Anatomical variations of the coeliac trunk branches are common in the Indian population. Understanding these variations is crucial for surgeons and radiologists to prevent complications during abdominal procedures.
Area of Science:
- Anatomy
- Vascular Anatomy
- Surgical Anatomy
Background:
- Anatomical variations of abdominal great vessels, particularly the coeliac trunk, are clinically significant for surgical planning and radiological interpretation.
- Accurate knowledge of these variations is essential for safe and effective medical interventions.
Purpose of the Study:
- To investigate and document the prevalence of anatomical variations in the branching pattern of the coeliac trunk within the Indian population.
- To provide data that can aid in improving surgical and radiological outcomes.
Main Methods:
- Dissection of 50 embalmed cadavers from the Indian population.
- Systematic observation and recording of the branching patterns of the coeliac trunk and its major arteries (left gastric, common hepatic, and splenic arteries).
Main Results:
- The typical trifurcation of the coeliac trunk into the left gastric, common hepatic, and splenic arteries was observed in 86% of cases.
- In 76% of cases, the left gastric artery originated proximal to the bifurcation into the common hepatic and splenic arteries.
- Atypical origins, including all three branches arising directly from the abdominal aorta, were noted in specific instances.
Conclusions:
- Variations in coeliac trunk branching patterns are prevalent and necessitate careful consideration in clinical practice.
- Awareness of these anatomical variations is vital for minimizing surgical complications such as bleeding and necrosis.
- This study contributes valuable anatomical data to enhance the accuracy of radiological interpretations and surgical procedures like liver transplantation.

01:25Abdominal 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.

01:15Thoracic 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,...
01:16Blood 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...

01:10The 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.

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...
01:27Nerve Supply of the GI Tract
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of the GI tract...
