Ans:A. Intrahepatic obstruction from cirrhosis
Image shows:
Uphill esophageal varices. Barium swallow demonstrates multiple serpiginous filling defects primarily involving the lower one third of the esophagus with striking prominence around the gastroesophageal junction. The patient had cirrhosis secondary to alcohol abuse.
Esophageal Varices
- Dilated submucosal veins due to increased collateral blood flow from portal venous system to azygos system
- Collateral blood flow from portal vein via azygos vein into SVC (usually lower esophagus drains via left gastric vein into portal vein)
- Most common cause is portal hypertension secondary to cirrhosis
- Varices in lower half of esophagus to the level of the carina (azygos vein)
- More common than downhill varices
Causes
- Intrahepatic obstruction from cirrhosis
- Splenic vein thrombosis (usually gastric varices only)
- Obstruction of hepatic veins
- IVC obstruction below hepatic veins
- Marked splenomegaly / splenic hemangiomatosis (rare)
Downhill varices
- Collateral blood flow from SVC via azygos vein into IVC / portal venous system (upper esophagus usually drains via azygos vein into SVC)
- Varices in upper 1/3 of esophagus
- Usually extend down to the level of the carina (azygos vein)
- Less common than uphill varices
Causes
- Obstruction of superior vena cava distal to entry of azygos vein due to
- Lung cancer (most common)
