Portal hypertension is a frequent consequence of liver disease, especially alcoholic cirrhosis. Unabated elevations in portal pressure may presage an esophageal variceal hemorrhage. Propranolol or isosorbide therapy is effective in the prophylaxis of variceal bleeding. In patients with acute variceal hemorrhage, endoscopic sclerotherapy or ligation is the best initial intervention. Stapled esophageal transection is often effective when endoscopic management fails. Surgical shunts have a lower associated mortality rate when they are performed electively and involve partial shunting of hepatic blood flow. Transjugular intrahepatic portosystemic shunts are indicated as a salvage procedure or as a bridge to liver transplantation. Ultimately, liver transplantation offers the best survival rate.
门静脉高压是肝脏疾病的常见后果,尤其是酒精性肝硬化。门静脉压力持续升高可能预示食管静脉曲张出血。普萘洛尔或异山梨酯疗法在预防静脉曲张出血方面有效。对于急性静脉曲张出血患者,内镜下硬化疗法或套扎术是最佳的初始干预措施。当内镜治疗失败时,吻合器食管横断术通常有效。选择性进行且涉及部分肝血流分流的手术分流术相关死亡率较低。经颈静脉肝内门体分流术适用于挽救性手术或作为肝移植的桥梁。最终,肝移植提供最佳生存率。
