Summary
A rare hepato-hepatic trunk variation, an incomplete coeliac axis, was found in a cadaver. This arterial anomaly, with separate splenic artery origin, highlights the need for anatomical knowledge in liver surgery.
Area of Science:
- Anatomy
- Vascular Surgery
- Radiology
Background:
- Aberrant arterial variations of the coeliac trunk are significant for surgical and radiological interventions.
- Precise anatomical knowledge is crucial for successful hepato-biliary procedures.
Purpose of the Study:
- To report a rare arterial variation: a hepato-hepatic trunk.
- To emphasize the importance of understanding coeliac trunk anomalies in surgical planning.
Main Methods:
- Case report of a rare arterial variation identified during cadaveric dissection.
- Detailed anatomical description of the aberrant branching pattern.
Main Results:
- Identification of a unique incomplete coeliac trunk, termed the hepato-hepatic trunk.
- Separate origin of the splenic artery from the abdominal aorta.
- Specific arrangement of hepatic arteries and gastric branches, including an absent left hepatic artery and a ring-shaped vascular structure around the caudate lobe.
Conclusions:
- This rare hepato-hepatic trunk variation underscores the diversity of coeliac trunk anatomy.
- Accurate pre-operative mapping of vascular variations is essential for liver transplantation, tumor therapy, and laparoscopic procedures.

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 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.

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,...

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 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...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
