Where does the superior mesenteric vein go?

The superior mesenteric vein is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the hepatic portal vein.

What does splenic vein drain?

The splenic vein drains the spleen, part of the pancreas, and part of the stomach.

What organ does the superior mesenteric vein supply?

How do you treat superior mesenteric vein thrombosis?

Anticoagulation is the treatment of choice for acute mesenteric venous thrombosis. Thrombolysis using systemic or transcatheter route is another option. Patients with peritoneal signs or refractory to initial measures require surgical exploration.

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.

How does the superior mesenteric vein drain blood from organs?

What is the superior mesenteric vein (SMV)?

The superior mesenteric vein (SMV) is a major venous tributary of the abdominal cavity.

Is the splenic vein turndown technique effective in blunt abdominal trauma?

Only one other case exists regarding the successful use of the splenic vein turndown technique in blunt abdominal trauma. Conclusion: There is little information regarding the feasibility and success of this technique in traumatic SMV disruption. Future studies are required to assess its role in abdominal vascular trauma.

What is splanchnic vein thrombosis?

Blood clotting within the splanchnic veinous systems leads to splanchnic vein thrombosis. It includes thrombosis in the splenic vein, mesenteric vein, portal vein, or hepatic vein (Budd-Chiari syndrome).
