Where is the splanchnic vein located?
The splenic vein is a large vessel located retroperitoneally in the upper part of the abdominal cavity. The main function of this blood vessel is to drain the venous blood from the spleen. In addition to the spleen, it drains parts of the stomach, pancreas and the hindgut.
Where does the splenic vein originate?
Origin and course The splenic vein is formed by splenic tributaries emerging at the splenic hilum in the splenorenal ligament at the tip of the tail of pancreas. It runs in the splenorenal ligament in close association with the splenic artery.
What are the tributaries of the splenic vein?
The tributaries of the splenic vein are the left gastro-epiploic vein, the inferior mesenteric vein, the short gastric vein, and the posterior pancreatic veins.
What forms the hepatic portal vein?
The hepatic portal vein (Figs 4.60, 4.61) is formed by the union of the superior mesenteric and the splenic veins behind the neck of the pancreas.
What is a splanchnic artery?
ANATOMY OF THE SPLANCHNIC ARTERIAL CIRCULATION The splanchnic circulation includes the celiac, superior mesenteric, and inferior mesenteric arteries, which arise from the abdominal aorta (Figure 1). The most proximal is the celiac artery, which has 3 branches: the left gastric, splenic, and common hepatic arteries.
Where does the splenic vein go?
The splenic vein (formerly the lienal vein) is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system. The splenic vein, here called the “lienal vein”, travels from the spleen, above the pancreas, and ends in the portal vein.
What are tributary veins?
Venous tributary – Glossary Ans : A smaller branch draining waste-products in blood into a larger vein.
What is the drainage of the splenic vein?

What is the difference between hepatic portal vein and hepatic vein?
What is the difference between the hepatic portal vein and the hepatic vein? The hepatic portal vein carries nutrient-rich blood from the intestine and other parts such as the gallbladder, pancreas and spleen to the liver, whereas the hepatic vein carries deoxygenated blood from the liver to the vena cava.
What are splanchnic veins?
The splanchnic circulation consists of the blood supply to the gastrointestinal tract, liver, spleen, and pancreas. It consists of two large capillary beds partially in series. The small splanchnic arterial branches supply the capillary beds, and then the efferent venous blood flows into the PV.
Is portal vein part of splanchnic circulation?
An increase in splanchnic blood flow in portal hypertension is the result of a marked vasodilation of arterioles in splanchnic organs, which drain blood into the portal venous system[35].
Does the splenic vein drain directly into the IVC?
On normal anatomy, typically, the splenic vein (SV) joins the superior mesenteric vein (SMV) anteriorly to the IVC and posteriorly to the pancreatic neck to form the PV, which ascends within the hepatoduodenal ligament, posteriorly to the hepatic artery and common bile duct, toward the hepatic hilum, where it divides …
How does blood travel from spleen to heart?
The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels.
