Intermediate Left Gastric Artery Quiz

Q1. Which branches of the left gastric artery ascend through or near the esophageal hiatus?

• Lumbar branches
• Sigmoid branches
• Cecal branches
• Esophageal branches

Q2. After reaching the cardia, how does the left gastric artery usually course?

• It crosses the sigmoid mesocolon
• It enters the splenic hilum
• It runs to the right along the lesser curvature
• It descends behind the kidney

Q3. Which arterial anastomosis forms the principal longitudinal connection along the lesser curvature?

• Left gastric with left colic artery
• Left gastric with ileocolic artery
• Left gastric with renal artery
• Left gastric with right gastric artery

Q4. Which gastric surface regions receive branches from the left gastric artery?

• Anterior and posterior gastric walls near the lesser curvature
• Only the serosa of the greater curvature
• Only the pyloric sphincter
• Only the gastric fundus

Q5. Which artery is the left gastric artery most directly connected to through its distal lesser-curvature anastomosis?

• Appendicular artery
• Right gastric artery
• Middle colic artery
• Inferior mesenteric artery

Q6. Which relationship is characteristic of the left gastric artery near the gastroesophageal junction?

• It gives esophageal branches near the cardia
• It enters the renal sinus
• It supplies the appendix
• It passes through the inguinal canal

Q7. Which thoracic arterial sources can anastomose with esophageal branches of the left gastric artery?

• Inferior rectal arteries
• Sigmoid arteries
• Esophageal branches of thoracic arteries
• Gonadal arteries

Q8. Why can the left gastric artery contribute to collateral circulation around the stomach?

• It is an end artery to the entire stomach
• It drains directly into the portal vein
• It participates in multiple gastric and esophageal anastomoses
• It has no arterial connections

Q9. Which celiac branch supplies the lesser curvature most directly?

• Splenic artery
• Left gastric artery
• Common hepatic artery
• Inferior pancreaticoduodenal artery

Q10. Which statement best describes the usual relationship of the left gastric artery to the lesser omentum?

• It courses within the lesser omentum along the lesser curvature
• It travels in the transverse mesocolon
• It is confined to the retroperitoneum
• It lies only in the greater omentum
