What does the inferior vena cava do?
The superior vena cava carries blood from the head, neck, arms, and chest. The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.
What causes enlarged inferior vena cava?
The IVC diameter is affected by right heart function, as well as conditions like IVC aneurysm or Budd-Chiari syndrome (BCS), which directly or indirectly increase the volume of the blood in the right heart or increase the back pressure on the systemic circulation ultimately leading to IVC dilation [2,3].
What is the inferior vena cava connected to?
Anatomical terminology. The ‘inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.
What are the major tributaries of the inferior vena cava and what is their distribution?
The inferior vena cava communicates with the superior vena cava through the collateral vessels, which include the azygos vein, lumbar veins, and vertebral venous plexuses. Inferior vena cava in a cadaver. Notice how the largest tributaries are the left and right renal veins.
Which is visceral tributaries of inferior vena cava?
The IVC has: Three anterior visceral tributaries (three hepatic) Three lateral visceral tributaries (suprarenal, renal, gonadal) Five lateral abdominal wall tributaries (inferior phrenic and four lumbar)
What is the most common cause of IVC enlargement?
Inferior Vena Cava Obstruction It most commonly occurs as a result of extension of iliac vein thrombosis and involves predominantly the infrarenal segment. Some conditions that predispose to IVC thrombosis include a central line extending to the IVC, previous surgery, trauma, and the presence of a caval filter.
What are the symptoms of inferior vena cava syndrome?
Inferior vena cava syndrome (IVCS) is characterized by tachycardia, hypotension, tachypnea, hypoxemia, and shortness of breath. The differential diagnosis of IVCS is broad, mainly because it is rarely ever diagnosed as a primary disease process.
Where is inferior vena cava located?
The inferior vena cava (IVC) is the largest vein of the human body. It is located at the posterior abdominal wall on the right side of the aorta. The IVC’s function is to carry the venous blood from the lower limbs and abdominopelvic region to the heart.
What vein typically drains directly into the inferior vena cava?
Portal veins branch out further in the liver parenchyma to form sinusoids. Sinusoids drain into the hepatic veins. Hepatic veins drain into the inferior vena cava, thus providing drainage of both portal and systemic blood into systemic circulation.
