The ligamentum teres hepatis is the obliterated umbilical vein, which joins the left portal vein; the ligamentum venosum is the obliterated ductus venosus, which joins the left portal vein to left hepatic vein.
What does ligamentum venosum represent?
The ligamentum venosum, also known as Arantius’ ligament, is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis. It may be continuous with the round ligament of liver.
What is ligamentum teres in abdomen?
Ligamentum teres (or round ligament) of the liver is a cord-like ligament found within the falciform ligament on the inner surface of the anterior abdominal wall and represents a remnant of the umbilical vein, which is a connecting venous structure between the placenta and the umbilical portion of the left portal vein.
Is round ligament and ligamentum teres the same?
The round ligament of the liver (or ligamentum teres, or ligamentum teres hepatis) is a ligament that forms part of the free edge of the falciform ligament of the liver. It connects the liver to the umbilicus. It is the remnant of the left umbilical vein.
Where is the ligamentum venosum located?
The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis (gateway to the liver). It may be continuous with the round ligament of liver (ligamentum teres hepatis).
What is the difference between the Ligamentum Arteriosum and the ductus arteriosus?
Ligamentum arteriosum (also known as Ligament of Botallo or Harvey’s ligament) is a fibrous remnant of the fetal ductus arteriosus (ductus Botalli, Botallo’s duct). The ductus arteriosus is a vessel connecting the pulmonary trunk and the aortic arch or descending aorta in the fetus.

The ligamentum venosum is the fibrous remnant of the ductus venosus of the fetal circulation. Usually, it is attached to the left branch of the portal vein within the porta hepatis (gateway to theliver). It may be continuous with the round ligament of liver (ligamentum teres hepatis).
What is the other name for round ligament?

The ligamentum teres is the remnant of the umbilical vein working throughout fetal life. Initially a pair of the umbilical veins entered the sinus venosus.
What is unique about ligamentum teres?
The ligamentum is considered particularly strong, even at birth, as a result of its collagenous formation, it is composed of collagen type I, III, IV. Gray and Villar [10] suggested that by virtue of the topography of the fovea the ligamentum is tightest in adduction, flexion and external rotation of the hip.
What is fissure for ligamentum teres?
The fissure for ligamentum teres sign or extrahepatic ligamentum teres sign is a radiographic sign of pneumoperitoneum. It represents the outline of the ligamentum teres (remnant of an obliterated left umbilical vein) with free abdominal gas in a supine patient, as seen on a plain abdominal radiograph.
What does falciform ligament carry in fetus?
The falciform ligament derives from the ventral mesentery, which is a part of the embryological foregut and forms a connection between the ventral abdominal wall and the liver. The umbilical vein, which is within the umbilical cord, carries oxygen-rich blood from the placenta to the fetal liver.
Where is the Ligamentum Venosum?
What does the ductus venosus become after birth?
[7] At birth, the remnant of the ductus venosus gradually develops into a ligament called the ligamentum venosum.
What is the remnant of the ductus venosus?
After it closes, the remnant is known as ligamentum venosum. If the ductus venosus fails to occlude after birth, it remains patent (open), and the individual is said to have a patent ductus venosus and thus an intrahepatic portosystemic shunt (PSS).
Where is the ligamentum venosum?
Is ligamentum teres a ligament?
What is the Ligamentum Teres? The ligamentum teres (LT) or ligamentum capitis femoris is a flat pyramidal shaped ligament located intra-articularly in the hip connecting the transverse acetabular ligament to the fovea capitis of the femoral head.
What is function of ligamentum teres?
They concluded that the ligamentum teres functions as a sling, preventing the femoral head from inferior subluxation during flexion and abduction. It may also provide stability to the hip joint when the capsuloligamentous structures are insufficient [12].
