Downhill Esophageal Varices: A Prevalent Complication of Superior Vena Cava Obstruction From Benign and Malignant Causes

摘要

Objective: Downhill esophageal varices (DEV) usually develop secondary to superior vena cava (SVC) obstruction. Downhill esophageal varices have been less well characterized compared to uphill varices. The aim of the study was to characterize the anatomy and etiology of DEV by contrast-enhanced computed tomography.
