What is calot triangle?
Calot triangle or cystohepatic triangle is a small (potential) triangular space at the porta hepatis of surgical importance as it is dissected during cholecystectomy. Its contents, the cystic artery and cystic duct must be identified before ligation and division to avoid intraoperative injury.
What is the node of calot?
The cystic lymph node of Lund (also known as the Calot or Mascagni node) is the sentinel node for the gallbladder, and one of the structures in Calot triangle. It lies in close proximity to the cystic artery and is one of the structures removed during cholecystectomy.
What is Rouviere’s sulcus?
Rouviere’s sulcus is a 2-3 cm cleft running to the right of the liver hilum anterior to segment 1 and is usually containing the right portal triad or its branches. The sulcus indicates the plane of common bile duct accurately.
Where is the common hepatic duct?
liver
A tube that carries bile from the liver. It starts where the right and left hepatic (liver) ducts join outside the liver. It ends where the cystic duct from the gall bladder joins it to form the common bile duct.
How do you perform a Cholangiogram?
How It’s Done
- Put a clip on the cystic duct, which runs right into your gallbladder. This stops anything from flowing in or flowing out.
- Then, put a thin tube into the cystic duct.
- Push a contrast dye into the tube, which helps highlight the bile ducts.
- Take live X-rays with a tool called a fluoroscope.
What is the definition of the triangle of Calot 1?
To the Editor:— Recently I came across the following definition of the triangle of Calot 1: The cystic duct, which is often tortuous and has a beaded appearance, passes downward and to the left to join the common duct; and the cysticartery arises from the hepatic artery and passes under the common hepatic duct to the gallbladder.
Is the cystic artery in the Calot triangle?
The Calot triangle, which contains the cystic artery, may also contain an accessory right hepatic artery or abnormal sectoral bile ducts. As a result, the dissection in Calot’s triangle is misguided until more lateral structures have been removed and the identification of the cystic duct is definitive.
Where is the Calot’s triangle located in the liver?
Calot’s Triangle. Calot’s triangle (cystohepatic triangle) is a small anatomical space in the abdomen. It is located at the porta hepatis of the liver – where the hepatic ducts and neurovascular structures enter/exit the liver.
When did Jean Francois Calot describe the isosceles triangle?
First described by Jean-François Calot as an “isosceles” triangle in his doctoral dissertation in 1891, this anatomical space requires careful dissection before ligature and division of the cystic artery and cystic duct during cholecystectomy.
