Esophageal varices can develop when cirrhosis (scarring) of the liver interrupts circulation. A thrombosis or blood clot in the vessels supplying the liver can also lead to esophageal varices. Schistosomiasis, a parasitic infection, causes damage to various bodily organs including the liver. This damage can interrupt blood flow and cause esophageal varices, as well.
