Intermediate Splenic Hilum Quiz

Q1. How does the splenic artery usually behave as it approaches the splenic hilum?

• It becomes the superior mesenteric artery
• It divides into terminal branches near the hilum
• It joins the inferior vena cava
• It remains a single unbranched vessel through the entire spleen

Q2. Why is the splenic hilum closely related to the pancreatic tail?

• The pancreatic head is fused to the splenic capsule
• The pancreatic tail approaches the hilum within the splenorenal ligament
• The main pancreatic duct enters the spleen
• The uncinate process surrounds the splenic artery

Q3. Which lymph nodes are closely associated with lymphatic drainage from the splenic hilum?

• Pancreaticosplenic lymph nodes
• Superficial inguinal lymph nodes
• Popliteal lymph nodes
• Submental lymph nodes

Q4. What is the relationship between the gastrosplenic ligament and splenic hilum?

• It attaches near the hilum and carries gastric vessels
• It carries the superior mesenteric vessels
• It contains the portal triad
• It attaches only to the diaphragmatic surface

Q5. What is the relationship between the splenorenal ligament and splenic hilum?

• It connects the spleen to the urinary bladder
• It transmits splenic vessels and the pancreatic tail toward the hilum
• It contains the inferior mesenteric artery
• It carries the common bile duct

Q6. Why are splenic arterial branches often described as segmental?

• They supply only the splenic capsule
• They supply relatively discrete splenic territories
• They form one continuous arterial ring inside the spleen
• They all drain directly into the portal vein

Q7. Which venous structure is formed by convergence of tributaries leaving the spleen near the hilum?

• Portal vein entirely within the spleen
• Splenic vein
• Inferior mesenteric artery
• Left renal vein

Q8. Which nerve plexus provides sympathetic fibers that travel along the splenic artery toward the hilum?

• Sacral plexus
• Celiac plexus
• Brachial plexus
• Lumbar somatic plexus

Q9. Why is the splenic hilum identifiable on cross-sectional imaging?

• Presence of the common bile duct inside the spleen
• Direct continuity with the inferior vena cava
• A large air-filled cavity within the spleen
• Convergence of splenic vessels at the medial visceral surface

Q10. Why must hilar vessels be carefully controlled during splenectomy?

• The hilum has no vascular structures
• The hilum contains major splenic arterial and venous branches
• The hilum contains only lymphatic capillaries
• The hilum contains the abdominal aorta
