What are the 4 anatomical lobes of the liver?
Anatomically the liver has four lobes: right, left, caudate, and quadrate. The quadrate lobe is located on the inferior surface of the right lobe. The caudate lobe is located between the left and right lobes in an anterior and superior location.
How many lobes does a cat liver have?
six lobes
The canine and feline liver consists of six lobes with several processes. In dogs and cats the liver is located within the ribcage.
What structure lies in between the left lobe of the liver and the caudate lobe?
The ligamentum venosum (the obliterated ductus venosus) is attached to the inferior surface of the liver between the caudate lobe and the left lateral sector.
What separates the left lobe from the caudate lobe?
The right lobe is separated from the other lobes by the gallbladder fossa and the fossa for the inferior vena cava on the visceral surface of the liver. The left lobe includes the caudate and quadrate lobes. The caudate lobe lies between the fissure for the ligamentum venosum and the fossa for the inferior vena cava.
Which of the following are names of lobes in a cat’s liver?
A cat liver has five lobes—right medial, right lateral, left medial, left lateral, and caudate—whereas a human liver only has four lobes.
Where is the caudate lobe located?
the liver
The caudate lobe of the liver is located deep in the liver, in front of the inferior vena cava (IVC) behind the three major hepatic veins, and cranial to the hilar plate.
How is the caudate lobe of the liver defined?
Discussion In the present study, we clearly defined the caudate lobe of the liver based on portal segmentation. The concept of diving the caudate lobe into three portions may be classical, but there has been no international consensus of the definition on the caudate lobe especially on the right-sided boundary of the paracaval portion of the liver.
What does the anatomy of the caudate lobe have to do with surgery?
The anatomy of the caudate lobe has technical and possibly oncologic implications for surgeons. The complex anatomy of the lobe is clarified by embryologic and anatomic analysis. This posterior sector is embryonically and anatomically independent of the right and left liver and the main portal fissu …
When is caudate lobectomy indicated in the treatment of hilar bile duct cancer?
In the case of hilar bile duct cancer, which may extend into the dorsal ducts (especially the right lateral duct), partial or total caudate lobectomy is often necessary for complete extirpation of the tumor.
Where does blood drain from the caudate lobe?
Blood from the caudate lobe drains directly into the vena cava. It is also known as the lobule of Spiegel. The caudate section of the liver is connected to the right lobe by a narrow bridge called the caudate process.
