Insights

A rare aberrant right hepatic artery variation was observed during cholecystectomy in a 91-year-old male. This anatomical finding highlights critical considerations for hepatobiliary surgery.

Area of Science:

  • Anatomy
  • Vascular Surgery
  • Surgical Education

Background:

  • Understanding arterial and hepatobiliary ductal anatomy is vital for safe cholecystectomy.
  • Aberrant arterial pathways can complicate surgical procedures.

Observation:

  • A unique right hepatic artery originating directly from the common hepatic artery was identified in a 91-year-old male.
  • This aberrant artery followed an unusual course, crossing the common bile duct anteriorly and passing the cystic duct posteriorly.

Findings:

  • The common hepatic artery sequentially branched into the left hepatic, right gastric, gastroduodenal, and the aberrant right hepatic arteries.
  • The aberrant right hepatic artery ascended on the right side of the common bile duct before entering the liver's right lobe.

Implications:

  • Recognition of this rare arterial anomaly is crucial for preventing intraoperative injury during hepatobiliary surgery.
  • This case underscores the importance of detailed preoperative imaging and anatomical knowledge in surgical planning.

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...
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...
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 responsible...
Blood Supply to the Digestive System01:16

Blood 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...
Arteries of the Upper Limbs01:12

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...
Thoracic Aorta01:15

Thoracic 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,...
