Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

3.5K
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...

Abdominal Aorta01:25

Abdominal Aorta

1.5K
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...

Esophageal Varices-I: Introduction01:24

Esophageal Varices-I: Introduction

630
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...

Esophageal Varices-II: Clinical Features and Management

220
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Hepatic Portal System01:21

Hepatic Portal System

3.8K
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...

Veins of Thorax01:19

Veins of Thorax

1.5K
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
The...

Area of Science:

  • Gastroenterology
  • Vascular Surgery
  • Anatomy

Background:

  • Upper gastrointestinal (GI) bleeding is a common clinical issue.
  • Accessory splenic arteries are rare vascular anomalies.
  • Previous literature describes only two cases of GI bleeding due to accessory splenic arteries.

Observation:

  • This report presents a unique case of upper GI bleeding.
  • The bleeding originated from a submucosal accessory splenic artery.
  • This anomalous artery arose from the left phrenic artery.

Findings:

  • The patient required multiple endoscopic interventions.
  • Endovascular embolization was necessary to control the bleeding.
  • This is the first reported instance of a submucosal accessory splenic artery causing GI hemorrhage.

Implications:

  • Vascular anatomic variants can complicate diagnosis and treatment.
  • Awareness of such anomalies is crucial for effective patient management.
  • This case expands the understanding of rare accessory splenic artery presentations and their clinical significance.
