Liver In The Arterees And It’s Branches Of Structure And Clinical Significance Of An Autopsy

Objective:To study the hepatic artery and its branches in the anatomical structure and distribution, measuring the length and diameter. Running records and variant hepatic artery site, increase the awareness of moving the hepatic artery, anatomy of the liver to provide a theoretical basis for the clinical operation of Hepatobiliary Surgery, etc. provide a reference.Materials and Methods:Non-liver deaths,30 cases were fixed in 10% formalin solution after soaking the body of adult liver samples, no rot, no damage, no lesions naked eye. Hepatoduodenal ligament and along the ligament of liver and stomach from the distal to the hepatic Glisson sheath stripping direction, the crack of portal area characteristics and with hilar channel structure in the observed hepatic artery of the course, branches and distribution of the backbone of the hepatic artery and its branches the length and arterial diameter measurements, measurements made caliper in millimeters.Results:1. Hepatic artery length 19.6±8.5mm (5.8-49.3mm), the diameter 4.0±0.13mm (2.3-6.9mm); left hepatic artery length 23.7±11.5mm (18.7-50.9mm),2.8 in diameter±0.3mm (1.4mm-5.5mm); right hepatic artery length 28.4±11.1mm (25.2-68.5mm), diameter of 3.1±0.5mm (1.3m-6.8mm).2. In accordance with the site of hepatic artery course and divided into four types:Ⅰtype left hepatic artery in the left lobe only found 83%(25 cases);Ⅱtype distribution of right hepatic artery in the right liver only 90%(27 cases);Ⅲtype distribution of right hepatic artery to the left liver in 17%(5 cases);Ⅳhepatic distribution to the right side of the left hepatic artery,10%(3 cases).3. Hepatic artery and its branches of distribution and variation of moving quite different patterns of variation of the liver is also more complex, by order analysis, carried out and summarized.Conclusion:1. Hepatic artery and its branches is proportional to the diameter and length, the longer the length, diameter of the more crude.2. By hepatic artery and its branches and the hepatic Traveling can be divided into different parts of four types.3. Hepatic artery branches varied greatly, the analysis concluded, liver and gallbladder surgery can approach the design and accurate positioning to provide anatomical basis for related structures.
