Summary
Hepatic artery variations occur in 33-41% of individuals. Careful cadaveric dissection is favored over angiography for defining aberrant hepatic arterial anatomy to prevent surgical complications.
Area of Science:
- Anatomy
- Vascular Surgery
- Surgical Education
Background:
- Hepatic arterial anatomy exhibits significant variation in 33-41% of individuals.
- Understanding aberrant anatomy is crucial for peripancreatic surgery and liver transplantation.
- Cadaveric dissections offer valuable insights into normal and variant arterial patterns.
Purpose of the Study:
- To document observed hepatic artery variations during cadaveric dissection.
- To characterize the macroscopic patterns of human hepatic arterial vascularization.
Main Methods:
- Dissection of twenty human cadavers of Caucasian origin.
- Study focused on the source and topographic arrangement of hepatic arterial supply.
Main Results:
- Nineteen cadavers (95%) displayed typical hepatic arterial supply originating from the celiac axis.
- One female cadaver (5%) presented with dual hepatic arterial supply to the liver and gallbladder.
- The dual supply involved an artery from the celiac axis and another from the superior mesenteric artery.
Conclusions:
- Aberrant hepatic vascularization necessitates preoperative assessment via imaging techniques to mitigate fatal complications.
- Careful surgical dissection is advocated as a superior method for defining arterial anatomy compared to angiography.

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.

01:21Hepatic Portal System
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...

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.
Encircling the heart, the coronary arteries form a ring-like structure before...

01:12Arteries of the Upper Limbs
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...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:11Overview of Systemic Arteries
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.
