Advanced Splenic Hilum Quiz

Q1. Why can ligation of individual terminal splenic arterial branches permit partial splenic resection?

• All splenic tissue receives blood only from short gastric arteries
• Terminal arterial branches supply relatively discrete splenic vascular territories
• Splenic segments are separated by cartilage
• The splenic artery has no branches at the hilum

Q2. What surgical risk arises from the pancreatic tail's proximity to the splenic hilum?

• Rupture of the urinary bladder
• Pancreatic tail injury with postoperative pancreatic leakage
• Obstruction of the urethra
• Injury to the right recurrent laryngeal nerve

Q3. Why may splenic hilar dissection be performed close to the spleen during spleen removal when preservation of the pancreatic tail is important?

• It can reduce the risk of injuring the nearby pancreatic tail
• It removes the need to control splenic vessels
• It prevents all gastric blood flow
• It avoids the diaphragm entirely

Q4. Which anatomical feature underlies the concept of superior and inferior vascular territories of the spleen?

• Attachment of the spleen to the falciform ligament
• Terminal branching of the splenic artery near the hilum
• Drainage by the inferior vena cava
• Division of the spleen by the pancreatic duct

Q5. Why can traction at the splenic hilum endanger the gastric fundus?

• The common bile duct attaches the fundus to the spleen
• The left renal artery enters the stomach
• Short gastric vessels connect the hilar region with the gastric fundus
• The portal vein directly connects the spleen to the fundus

Q6. How does the splenic hilum relate to the lesser sac?

• It lies within the right paracolic gutter
• It is located in the pelvic cavity
• It lies adjacent to peritoneal folds at the left side of the lesser sac
• It forms the epiploic foramen itself

Q7. Why is vascular variation at the splenic hilum surgically important?

• The spleen is always supplied by a single vessel with no branches
• The splenic artery always enters through the diaphragmatic surface
• Hilar veins never vary
• Terminal splenic vessel branching patterns vary between individuals

Q8. Which relationship best explains why distal pancreatic surgery and splenic hilar surgery are anatomically linked?

• The uncinate process forms the splenic capsule
• The pancreatic head lies inside the splenic hilum
• Pancreatic tail and splenic vessels converge near the hilum within the splenorenal ligament
• The spleen shares a duct with the pancreas

Q9. How does the absence of extensive intraparenchymal arterial anastomosis affect splenic vascular territories?

• Splenic perfusion depends entirely on the inferior mesenteric artery
• Occlusion of a terminal branch can produce localized segmental ischemia
• All terminal branches freely compensate for one another
• Every arterial occlusion immediately affects only the stomach

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

• It is an avascular region on the superior splenic border
• It is a retroperitoneal duct connecting the spleen to the kidney
• It is the visceral gateway for splenic vessels, nerves, lymphatics, and adjacent peritoneal ligament relationships
• It is the smooth convex surface facing the diaphragm
