Intermediate Suprarenal Veins Quiz

Q1. With which vein does the left suprarenal vein commonly unite before entering the left renal vein?

• Inferior mesenteric vein
• Portal vein
• Right gonadal vein
• Left inferior phrenic vein

Q2. Why is the right suprarenal vein surgically important during adrenalectomy?

• It is short and enters the inferior vena cava directly
• It is the longest adrenal vein
• It drains into the portal vein
• It passes through the renal pelvis

Q3. Why is the left suprarenal vein often easier to identify and control than the right during surgery?

• It has no connection to a major vein
• It usually has a longer extra-adrenal course
• It is located inside the renal pelvis
• It drains into the inferior vena cava through a shorter course

Q4. What structural feature is characteristic of the central adrenal vein?

• Cartilage rings
• Skeletal muscle fascicles
• Prominent longitudinal smooth muscle
• Keratinized epithelium

Q5. What is the relationship between the central adrenal vein and the gland's sinusoidal circulation?

• The central vein supplies arterial blood to the cortex
• Sinusoids converge toward the central adrenal vein
• The central vein drains only the capsule
• Sinusoids empty into the renal pelvis

Q6. How does adrenal venous anatomy contrast with adrenal arterial anatomy?

• Many arterial branches converge to a dominant suprarenal vein
• The adrenal gland has no venous drainage
• Both systems consist of a single vessel
• One artery accompanies dozens of major suprarenal veins

Q7. Which nearby vessel is most at risk if the right suprarenal vein is avulsed at its termination?

• Splenic vein
• Inferior vena cava
• Left renal artery
• Superior mesenteric artery

Q8. What route does blood from the left adrenal gland usually follow to reach the inferior vena cava?

• Left suprarenal vein to inferior mesenteric vein to portal vein
• Left suprarenal vein to left renal vein to inferior vena cava
• Left suprarenal vein to portal vein to inferior vena cava
• Left suprarenal vein to splenic vein to portal vein

Q9. Why is knowledge of the left inferior phrenic vein relevant in left adrenal surgery?

• It drains directly into the renal pelvis
• It is the principal artery of the gland
• It replaces the left renal vein
• It commonly joins the left suprarenal vein

Q10. Which side demonstrates the greater asymmetry between a very short adrenal vein and a nearby large central vein?

• Left side
• Right side
• Neither side
• Both sides are anatomically identical
