Advanced Gastrosplenic Ligament Quiz

Q1. Why can division of the gastrosplenic ligament cause gastric bleeding if performed without vascular control?

• It contains the inferior vena cava
• It contains short gastric and left gastro-omental vessels
• It contains the superior mesenteric artery
• It contains the hepatic veins

Q2. Which developmental event is central to formation of the gastrosplenic ligament?

• Development of the spleen within the dorsal mesogastrium followed by gastric rotation
• Rotation of the midgut around the inferior mesenteric artery
• Fusion of the ventral pancreatic bud with the liver
• Descent of the gonads through the inguinal canal

Q3. How does the gastrosplenic ligament participate in peritoneal compartment anatomy?

• It closes the epiploic foramen from the right
• It separates the pleural cavities
• It forms the entire anterior abdominal wall
• It contributes to the left-sided peritoneal boundary of the lesser sac

Q4. Which vascular relationship distinguishes the gastrosplenic ligament from the splenorenal ligament?

• It contains no vascular structures
• It carries gastric vessels rather than the main splenic vessels and pancreatic tail
• It carries the portal triad rather than gastric vessels
• It contains the superior mesenteric vessels

Q5. Why can excessive traction on the gastric fundus during splenic mobilization injure vessels?

• Short gastric vessels directly tether the fundus to the splenic hilar region
• The inferior mesenteric vein anchors the fundus
• The portal vein directly tethers the fundus to the spleen
• The renal artery runs through the gastric wall

Q6. Which anatomical plane is entered when the gastrosplenic ligament is divided to access the space posterior to the stomach?

• Pericardial cavity
• Lesser sac
• Pleural cavity
• Retrovesical space

Q7. How does the ligament's embryologic origin explain its relationship to the spleen?

• The spleen develops from the mesonephric duct
• The spleen develops in the ventral mesogastrium beside the liver
• The spleen develops from pancreatic endoderm
• The spleen develops within the dorsal mesogastrium from which the ligament is derived

Q8. Why must the left gastro-omental vessels be considered near the inferior portion of the gastrosplenic ligament?

• They pass from the splenic region toward the greater curvature within the ligament
• They enter the liver through the porta hepatis
• They supply the sigmoid colon
• They descend with the ureter

Q9. What relationship allows disease or fluid in the lesser sac to be anatomically close to the gastrosplenic ligament?

• The ligament lies in the posterior mediastinum
• The ligament is part of the left-sided boundary relationships of the lesser sac
• The ligament forms the pelvic floor
• The ligament is completely retroperitoneal

Q10. Which statement best integrates the anatomy of the gastrosplenic ligament?

• It is a ventral-mesogastrium-derived fold carrying the portal triad
• It is a retroperitoneal fascia connecting pancreas to kidney
• It is a vascular peritoneal fold between stomach and spleen derived from the dorsal mesogastrium
• It is a pleural fold connecting spleen to diaphragm
