Advanced Splenic Vein Quiz

Q1. Why is the splenic vein particularly relevant during pancreatic surgery?

• It is confined to the liver
• It is closely related to the posterior pancreatic body and tail
• It passes through the urinary bladder
• It lies inside the common bile duct

Q2. Which venous pathway can enlarge when splenic venous outflow is obstructed near the pancreas?

• Pulmonary veins
• Hepatic veins only
• Short gastric and gastro-omental veins
• Cerebral veins

Q3. Why can splenic vein obstruction produce prominent gastric venous collaterals?

• The splenic vein is an artery supplying the stomach
• The renal veins drain directly into the gastric lumen
• The gastric fundus drains only to the inferior vena cava
• Short gastric veins connect the gastric fundus with the splenic venous system

Q4. Which anatomical relationship explains why pancreatic inflammation can affect splenic venous flow?

• The vein is separated from the pancreas by the vertebral canal
• The vein lies only in the pelvis
• The vein lies within the gallbladder
• The vein lies immediately posterior to the pancreas

Q5. Which variation in inferior mesenteric venous drainage changes the tributary pattern of the splenic vein?

• Inferior mesenteric drainage into the aorta
• Inferior mesenteric drainage to the superior mesenteric vein or portal confluence
• Inferior mesenteric drainage to the pulmonary trunk
• Inferior mesenteric drainage into the common bile duct

Q6. Which developmental venous system forms the main embryologic basis of the portal venous channels receiving splenic blood?

• Umbilical arteries only
• Vitelline venous system
• Posterior cardinal arteries
• Anterior cardinal arteries

Q7. Why can preservation of the splenic vein be technically difficult in spleen-preserving distal pancreatectomy?

• The vein has no pancreatic tributaries
• The vein passes through the pancreatic duct
• Numerous pancreatic tributaries tether the vein to the pancreas
• The vein is fused to the aorta

Q8. Which venous route can provide an alternative drainage pathway from the spleen when the main splenic vein is not preserved but the spleen remains?

• Short gastric and gastro-omental collateral pathways
• Portal arteries through the liver
• Renal arteries through the kidney
• Hepatic veins through the gallbladder

Q9. How does the splenic vein differ from the major hepatic veins in relation to hepatic circulation?

• The splenic vein contributes to portal inflow, while hepatic veins provide hepatic outflow
• Both drain the liver directly into the inferior vena cava
• The splenic vein is an artery
• Hepatic veins carry blood from the spleen to the portal vein

Q10. Which statement best integrates the anatomy of the splenic vein?

• It is an arterial branch of the celiac trunk
• It drains directly from the spleen into the inferior vena cava
• It courses from the splenic hilum behind the pancreas and joins the superior mesenteric vein to form the portal vein
• It travels through the hepatoduodenal ligament as a hepatic outflow vein
