What is the middle hepatic vein?
Middle hepatic vein: This vein runs at the middle portal fissure, dividing the liver into right and left lobes. It runs just behind the IVC. Left hepatic vein: This vein is found in the left portal fissure, splitting up the left lobe of the liver into a more medial and lateral sections.
What is a right hepatectomy?
Right hepatectomy is a well-standardized procedure consisting of resection of liver parenchyma on the right side of Cantlie’s line in the right side of the MHV (see Fig. 108B. 4). The inclusion of the MHV corresponds to an extended right hepatectomy.
What does the middle hepatic vein drain?
The hepatic veins are the veins that drain de-oxygenated blood from the liver into the inferior vena cava. There are usually three upper hepatic veins draining from the left, middle, and right parts of the liver….

What are the 3 major hepatic veins?
Three large intrahepatic veins drain the liver parenchyma, into the inferior vena cava (IVC), and are named the right hepatic vein, middle hepatic vein and left hepatic vein. The veins are important landmarks, running in between and defining the segments of the liver.
What is the right hepatic vein?
The right hepatic vein is the largest. It divides your liver’s right lobe from front to back. The left hepatic vein divides the left lobe from left to right. Each hepatic vein can have two or more branches inside the liver.
What does the right hepatic vein drain?
The right hepatic vein drains the segments VI and VII, and occasionally parts of segments V and VIII. The vein terminates by draining into the inferior vena cava near the upper border of the caudate lobe of the liver, just below the central tendon of the diaphragm.
How do you do a right hepatectomy?
Conclusion. The preliminary results of this 5-steps stapling technique for right hepatectomy using the liver hanging maneuver are encouraging as the technique resulted in little intraoperative blood loss and short operation time, and it caused no major complications and mortality.
Can the right lobe of the liver be removed?
This is called a liver resection (or a hepatectomy). The liver is made up of two halves called the right lobe and the left lobe. If the entire right lobe is to be removed, that is called a right hepatectomy, and if the left lobe is to be removed that is a left hepatectomy.
What causes dilated hepatic vein?
Passive hepatic congestion, also known as congested liver in cardiac disease, describes the stasis of blood in the hepatic parenchyma, due to impaired hepatic venous drainage, which leads to the dilation of central hepatic veins and hepatomegaly.
What is the function of hepatic artery and hepatic vein?
The liver receives a blood supply from two sources. The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients.
What organs are drained by the hepatic vein?
Approximately 75% of total liver blood flow is through the portal vein, with the remainder coming from the hepatic artery proper. The blood leaves the liver to the heart in the hepatic veins….
