Vascular anomalies are a serendipitous finding during surgeries and diagnostic angiography. Such variations are frequently encountered in the abdominal region. These anomalies are usually asymptomatic but the presence of hepatic arterial variations may lead to injuries of the liver during surgery. The present study was conducted on 35 adult embalmed cadavers, 31 males, 4 females from August 2015 to December 2021 in the Department of Anatomy, Amrita School of Medicine, Amrita Institute of Medical Sciences, Kochi. In this study of 35 cadavers, we present 3 variants: an accessory right hepatic artery, replaced common hepatic artery, replaced common hepatic artery anastomosis with accessory left hepatic artery and an arc of Buhler. One of our variants has not yielded a precedent in literature search. We have compared these variants with Michels and Hiatt classification. It is known that different variants arise at distinct stages of embryonic development. As specialists in anatomy, we have tried to correlate the variants in our study with their embryological origins.

Hepatic Portal System01:21

Hepatic 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...

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...

Arteries 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...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Overview 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...

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...
