Summary
Anatomic variants in abdominal arteries are common. This case highlights a rare variant of the hepatic artery and gastroduodenal artery, crucial for surgical planning.
Area of Science:
- Vascular anatomy
- Surgical planning
- Medical imaging
Background:
- Anatomic variants of the celiac trunk and superior mesenteric artery are frequently encountered.
- Knowledge of these variations is critical for successful preoperative planning in abdominal surgeries and interventional procedures.
Observation:
- A rare case of replaced proper hepatic artery and replaced gastroduodenal artery was identified using CT angiography and diagnostic angiography.
- The patient presented with upper gastrointestinal hemorrhage.
Findings:
- The common hepatic artery was absent, with aberrant origins for its branches.
- The replaced proper hepatic artery originated from the superior mesenteric artery.
- The replaced gastroduodenal artery originated from the gastrosplenic trunk.
Implications:
- This case underscores the necessity of thorough preoperative imaging analysis.
- Identifying such vascular anomalies is vital to prevent intraoperative complications during abdominal surgery and interventional procedures.

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.

01:16Blood Supply to the Digestive System
3.4K
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...

01:21Hepatic Portal System
3.4K
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...

01:24Esophageal Varices-I: Introduction
552
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

01:15Thoracic Aorta
964
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,...

01:17Gross Anatomy of the Liver
1.3K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...
