Chapter 51: Liver- Anatomy Flashcards
Identify the branches of the celiac trunk
- Celiac trunk
- Splenic artery
- Left gastric artery
- Common hepatic artery
- Gastroduodenal artery
- Proper hepatic artery
- Left hepatic artery
- Right hepatic artery
What is the venous supply?
Portal vein (formed from the splenic vein and the superior mesenteric vein)
What is the hepatic venous drainage?
Via the hepatic veins, which drain into the IVC (three veins: left, middle, andright)
What sources provide oxygen to the liver?
Portal vein blood—50%
Hepatic artery blood—50%
From what sources does the liver receive blood?
Portal system—75%
Hepatic artery system—25%
Identify the segments of the liver (French system)
What is the overall arrangement of the segments in the liver?
Clockwise, starting at segment 1
What is the maximum amount of liver that can be resected while retaining adequate liver function?
>80%
What is Child’s class? (Child–Turcotte–Pugh)
Classification system that estimates hepatic reserve in patients with hepatic failure and mortality
How can the criteria comprising the modified Child’s classification be remembered?
Use the acronym: “A BEAP”:
Ascites
Bilirubin
Encephalopathy
Albumin
PT (prothrombin time)
What is the operative mortality for a portacaval shunt versus overal lintraabdominal operations with cirrhosis in the following Child’s classes:
A
<5% versus overall = 10%
What is the operative mortality for a portacaval shunt versus overal lintraabdominal operations with cirrhosis in the following Child’s classes:
B
<15% versus overall = 30%
What is the operative mortality for a portacaval shunt versus overal lintraabdominal operations with cirrhosis in the following Child’s classes:
C
≈33% versus overall = 75%
What does the MELD score stand for?
Model for End-stage Liver Disease
What is measured in the MELD score?
- INR
- total bilirubin
- serum creatinine (SCR)
