2023年10月9日 · 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. In this article, we shall look at the borders, contents and clinical relevance of Calot’s triangle.

Drawings of the Calot's triangle from anatomy texts are very different from the anatomy seen during the performance of a cholecystectomy. In the first place all the structures forming the boundaries of the Calot's triangle are not seen during surgery as they are covered with tissue.

2024年8月28日 · The hepatocystic triangle, also known as hepatobiliary triangle or Calot triangle, is a small 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.

The cystohepatic triangle (or hepatobiliary triangle or Calot's triangle) is an anatomic space bordered by the cystic duct laterally, the common hepatic duct medially, and the inferior surface of the liver superiorly.. Cystohepatic triangle, marked with green. The cystic artery lies within the hepatobiliary triangle. The triangle is used to locate the cystic artery during a laparoscopic ...

2023年1月23日 · The hepatocystic triangle (triangle of Calot) is a surgical anatomical landmark created by the cystic duct laterally, the common hepatic duct medially, and the liver edge superiorly. This triangle is of surgical importance because this is the location for the most common path of the cystic artery to the gallbladder.

Calot's triangle is an anatomical landmark of special value in cholecystectomy. First described by Jean-François Calot as an "isosceles" triangle in his doctoral thesis in 1891, this anatomical space requires careful dissection before the ligation and division of the cystic artery and cystic duct during cholecystectomy.

The Triangle of calot (Hepatocystic Triangle) is anatomical space located near the porta hepatis. It is an area of focus during cholecystectomy. The Triangle of calot is defined by three structures: Superior: Inferior surface of the liver; Lateral: Cystic Duct; Medial: Common Hepatic Duct. The cystic artery normally resides within the triangle ...

2023年10月13日 · Calot’s triangle, also known as the cystohepatic triangle, is a well-known feature of hepatobiliary system that is recognized and dissected during safe cholecystectomy. In various modern textbooks, the borders of Calot’s triangle are defined to be the inferior surface of the liver superiorly, the cystic duct laterally and the common hepatic ...

The latter is often enlarged due to inflammation of the gallbladder (e.g., cholecystitis ) or biliary tract (e.g., cholangitis) and can be removed along with the gallbladder during surgical treatment (cholecystectomy). The Calot triangle, which contains the cystic artery, may also include an accessory right hepatic artery or abnormal sectoral bile ducts.

2016年9月7日 · CHAPTER 8 Cholecystectomy Ashley H. Vernon Step 1. Surgical anatomy ♦ The triangle of Calot is the most important anatomic boundary that needs to be defined when performing cholecystectomy. It is formed by the boundaries of the cystic duct, common hepatic duct, and cystic artery. ♦ Roughly parallel to this triangle is the hepatocystic triangle…
