Advanced Splenic Vein Quiz

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

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

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

• Hepatic veins only
• Short gastric and gastro-omental veins
• Pulmonary veins
• Cerebral 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 lies immediately posterior to the pancreas
• The vein is separated from the pancreas by the vertebral canal
• 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 into the aorta
• Inferior mesenteric drainage to the pulmonary trunk
• Inferior mesenteric drainage to the superior mesenteric vein or portal confluence
• 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?

• Posterior cardinal arteries
• Vitelline venous system
• Umbilical arteries only
• Anterior 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
• The vein has no pancreatic tributaries
• 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?

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

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

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

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

• 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 is an arterial branch of the celiac trunk
• It drains directly from the spleen into the inferior vena cava
