Recurrent Hematemesis From Downhill Esophageal Varices: A Therapeutic Challenge for Gastroenterologists.

Downhill or upper esophageal varices have an etiology that differs from that of the "uphill" varices secondary to portal hypertension. Approximately 0.1% of all cases of variceal hemorrhage are due to downhill varices. The underlying etiology is obstruction of the superior vena cava (SVC) which results in the shunting of blood from the systemic circulation into the esophageal plexus, predominantly the upper two-thirds. The management should be directed to relieve the vascular obstruction. One of the causes of SVC obstruction leading to downhill variceal bleeding is dialysis catheter-associated SVC stenosis. We report the case of a 34-year-old male with hematemesis associated with downhill varices due to chronic SVC obstruction because of a central venous catheter.
