The umbilical arteries are actually the anterior division of the internal iliac arteries, and retain part of this function after birth. [3] The umbilical arteries are one of two arteries in the human body, that carry deoxygenated blood, the other being the pulmonary arteries. The pressure inside the umbilical artery is approximately 50 mmHg. [4]
An umbilical line is a catheter that is inserted into one of the two arteries or the vein of the umbilical cord.Generally the UAC/UVC (Umbilical Artery Catheter/Umbilical Vein Catheter) is used in Neonatal Intensive Care Units (NICU) as it provides quick access to the central circulation of premature infants.
As the umbilical vein is directly connected to the central circulation, it can be used as a route for placement of a venous catheter for infusion and medication. The umbilical vein catheter is a reliable alternative to percutaneous peripheral or central venous catheters or intraosseous canulas and may be employed in resuscitation or intensive ...
The medial umbilical ligament, cord of umbilical artery, or obliterated umbilical artery is a paired structure found in human anatomy. It is on the deep surface of the anterior abdominal wall , and is covered by the medial umbilical folds ( plicae umbilicales mediales ).
In some situations, venous access is obtained by inserting catheters into the large central veins of the trunk of the body such as the internal jugular, subclavian, or femoral veins. This type of venous access is performed with central venous catheters (CVCs) , and is required in certain situations where peripheral access is inadequate.
CVCs can be mistakenly placed in an artery during insertion (for example, the carotid artery or vertebral artery when placed in the neck or common femoral artery when placed in the groin). During subclavian vein central line placement, the catheter can be accidentally pushed into the internal jugular vein on the same side instead of the ...
Steps in a TIPS procedure: A) portal hypertension has caused the coronary vein (arrow) and the umbilical vein (arrowhead) to dilate and flow in reverse. This leads to varices in the esophagus and stomach, which can bleed; B) a needle has been introduced (via the jugular vein) and is passing from the hepatic vein into the portal vein; c) the ...
Occasionally, during pregnancy, there is a single umbilical artery (SUA) present in the umbilical cord, as opposed to the usual two. [1] This is sometimes also called a two-vessel umbilical cord, or two-vessel cord. Approximately, this affects between 1 in 100 and 1 in 500 pregnancies, making it the most common umbilical abnormality.
