Advanced Splenic Vein Quiz

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

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

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

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

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

• 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
• The splenic vein is an artery supplying the stomach

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

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

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

• Inferior mesenteric drainage to the superior mesenteric vein or portal confluence
• Inferior mesenteric drainage into the aorta
• 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?

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

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

• The vein passes through the pancreatic duct
• Numerous pancreatic tributaries tether the vein to the pancreas
• The vein has no pancreatic tributaries
• 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 is an artery
• The splenic vein contributes to portal inflow, while hepatic veins provide hepatic outflow
• Both drain the liver directly into the inferior vena cava
• 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 travels through the hepatoduodenal ligament as a hepatic outflow vein
• It courses from the splenic hilum behind the pancreas and joins the superior mesenteric vein to form the portal vein
• It drains directly from the spleen into the inferior vena cava
