Where is the splenic confluence?
Also called the portal splenic confluence. This is the area where the splenic vein meets the superior mesenteric vein. Together, posterior to the neck of the pancreas, these veins form the portal vein.
What does the splenic vein drain?
blood
What is splenorenal shunting?
The splenic vein (a part of the portal vein), is connected to the renal vein.
Is the portal confluence composed of superior mesenteric vein or inferior mesenteric vein and splenic vein?
AnswerThe portal confluence is the area where the superior mesenteric vein and the splenic vein meet. They run posterior to the pancreas and form the portal vein.
What does the inferior mesenteric vein drain?
The Inferior Mesenteric Vein (iMV) drains into the splenic vein. The splenic vein ultimately "meets up" with the Superior Mesenteric Vein (SMV) to form the Hepatic Portal Vein (HPV)
The hepatic portal system is formed by the union of?
Splenic vein and superior mesenteric vein.
Can splenic vein thrombosis cause variceal bleeding?
yes
What are the three veins that form and empty the hepatic portal vein?
The hepatic portal vein is created by the anastamoses between the superior mesenteric vein and spleinc vein. It is arguable that the inferior mesenteric vein joins at this same anastomoses but generally it actually joins the splenic vein which then meats the sup. mesenteric vein as stated above. The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.
Which vessels drain into the hepatic portal vein?
inferior mesentaric and splenic
When is the spleen removed during a pancreatectomy?
If the disease affects the splenic artery or vein, the spleen is also removed.
What is the purpose of a splenoportography?
It is used to diagnose blockages in the splenic vein and portal-vein thrombosis and to assess the patency and location of the vascular system prior to liver transplantation.
How do insulin and glucagon reach distant cells in the liver?
To understand you need to know the anatomy of the portal vein system. The pancreatic veins drain into the major splenic vein which all drain into the hepatic portal vein. Although the artery supplying the pancreas is directly from the desceding aorta. The hepatic portal vein drains into the Liver. So insulin and glucagon are released into the splenic vein and eventually reach the liver via the portal system.
