While alcoholic cirrhosis is the most common cause of portal hypertension and associated gastrointestinal bleeding, portal vein occlusion can produce similar clinical manifestations. Ultrasonography is an accurate, noninvasive procedure for detecting portal vein thrombosis and distinguishing infrahepatic venous obstruction from intrahepatic obstruction due to cirrhosis.
虽然酒精性肝硬化是门静脉高压及相关胃肠道出血的最常见原因，但门静脉闭塞也可产生类似的临床表现。超声检查是一种准确的无创检查方法，可用于检测门静脉血栓形成，并区分肝下静脉阻塞与肝硬化所致的肝内阻塞。
