What vein does the splenic vein drain into?
Hepatic portal vein
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….Splenic vein.
| Drains from | Splenic lobar veins |

| Drains to | Hepatic portal vein |
Is splenic a vein or artery?
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….

| Artery | splenic artery |

Where is the splenic artery and vein located?
The splenic artery is one of the terminal branches of the celiac trunk, passing left from the celiac axis across the left crus of diaphragm and left psoas muscle. It is a tortuous artery, running superior to the pancreas before turning forward into the splenorenal ligament to the hilum of the spleen.
What order is the splenic artery?
Splenic artery
| Origin | Celiac trunk |
|---|---|
| Branches | Pancreatic branches (dorsal pancreatic, transverse, and greater pancreatic artery); short gastric arteries, left gastroepiploic artery, posterior gastric |
| Supply | Pancreas, stomach, spleen |
Does the splenic vein have valves?
The spleen may be regarded as a specialized portion of the portal reservoir. Valves are absent from the portal vein and its large tributaries, but are present in some of its smaller tributaries, notably the gastric veins.
What happens when the splenic vein is occluded?
Obstruction of splenic venous outflow leads to the enlargement of collateral vessels along the short gastric and gastroepiploic veins, which results in the formation of gastric varices along the greater curvature and fundus of the stomach, as well as esophageal varices secondary to increased flow to the coronary vein.
Is splenic artery an end artery?
Arteries which do not anastomose with their neighbors are called end arteries. There is no collateral circulation present besides the end arteries. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.
What does splenic artery mean?
Splenic artery: A large artery within the abdomen that arises from an arterial vessel called the celiac trunk, which emerges from the aorta. The splenic artery supplies blood not only to the spleen, but also to the esophagus, stomach, duodenum, liver, and pancreas.
What is the normal size of splenic vein?
The mean splenic length was 10.29 ± 1.89 cm. The mean portal vein diameter was 10.27 ± 1.78 mm. A statistically significant correlation was found between the spleen size and portal vein diameter; the Pearson correlation was significant at the 0.01 level.
What does the splenic artery give rise to?
The splenic artery or lienal artery is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas….Structure.
| Branch | Description |
|---|---|
| posterior gastric | posterior of stomach, gastric region superior to the splenic artery |
What two major veins lack valves?
In adults, the portal vein and its tributaries have no valves; in the fetus and for a short postnatal period valves are demonstrable in the tributaries, usually atrophying but occasionally persisting in degenerate form.
How do you know if you have a splenic vein?
The splenic vein lies posterior to and closely approximated to the body of the pancreas, and it runs from the pancreatic tail to the neck of the gland. Immediately dorsal to the neck, the splenic vein joins with the superior mesenteric vein to form the portal vein.
What is the function of the splenic vein?
The splenic vein works in opposition to the splenic artery, which branches off the celiac artery. The splenic artery feeds oxygenated blood to the spleen and the surrounding areas, and the course of the splenic vein runs close to the artery. Since the spleen is vital to the circulatory system, it needs constant functionality…
What does the splenic artery supply to the spleen?
The splenic artery feeds oxygenated blood to the spleen and the surrounding areas, and the course of the splenic vein runs close to the artery. Since the spleen is vital to the circulatory system, it needs constant functionality from both blood vessels.
What are the tributaries of the splenic vein?
Along its course, the splenic vein receives several tributaries that drain the surrounding structures. These tributaries include: The short gastric veins, which drain the fundus of the stomach. The left gastroomental (gastroepiploic) vein, which drains the greater curvature of the stomach.
What vein drains blood away from the spleen?
Splenic vein. As such, the spleen’s role is not only active in the circulatory system, but in the body’s immune system as well. Formerly the lienal vein, the splenic vein services the spleen. It drains deoxygenated blood away from the spleen to a junction with the superior mesenteric vein. As a result, the hepatic portal vein is formed.
