hard · MCQ · Q-DE23CF
A 60-year-old male with a history of cirrhosis presents with hematemesis. Doppler ultrasound of the abdomen reveals hepatofugal flow in the portal vein, splenomegaly, and a dilated tortuous vessel running along the lesser curvature of the stomach. Which of the following collateral pathways is primarily responsible for the vessel seen along the lesser curvature?
- A.Left gastric vein (coronary vein) to esophageal veinsCorrect answer
- B.Inferior mesenteric vein to rectal veins
- C.Paraumbilical veins to subcutaneous abdominal veins
- D.Splenic vein to short gastric veins
Solution
Portal hypertension leads to portosystemic collaterals. The left gastric vein (also known as the coronary vein) communicates with the lower esophageal veins, forming gastroesophageal varices which are commonly visualized along the lesser curvature of the stomach and distal esophagus. This is the most common pathway leading to variceal bleeding.
