门脉高压（Portal hypertension）为描述肝门静脉系统高压的状态。目前的定义为肝门静脉梯度高于或等于6mmHg[1]。门脉高压最常见的原因就是肝硬化，其他较罕见的原因则称为非肝硬化性门脉高压（non-cirrhotic portal hypertension）。当门脉高压已造成问题，则必须适当纾解门脉压力[来源请求]。
症状和征象
门脉高压的症状和征象包含：
病因
门脉高压可借由病灶发生的位置分为肝前性、肝内性、肝后性等。最常见的因素为肝硬化，其他原因则包含[2][5][6]：
| 非肝硬化性门脉高压的相关因子 | |
|---|---|
| 肝前性 | 门静脉或脾静脉血栓 |
| 动静脉瘘管 | |
| 脾肿大（增加门脉血流） | |
| 肝内性 | 所有造成肝硬化的原因，包含酗酒、慢性病毒性肝炎、胆道闭锁等等 |
| Primary biliary cirrhosis | |
| Primary sclerosing cholangitis | |
| Chronic pancreatitis | |
| Hereditary haemorrhagic telangiectasia | |
| 血吸虫症 | |
| Congenital hepatic fibrosis | |
| Nodular regenerative hyperplasia | |
| Fibrosis of space of Disse | |
| Granulomatous or infiltrative liver diseases (Gaucher, mucopolysaccharidosis, sarcoidosis, lymphoproliferative malignancies, amyloid deposition, …) | |
| 毒素（如砷、铜、氯乙烯、矿物油、维生素A、azathioprine、dacarbazine、methotrexate、amiodarone...） | |
| 病毒性肝炎 | |
| 脂肪肝 | |
| Veno-occlusive disease | |
| 肝后性 | 下腔静脉阻塞 |
| (Right-sided) heart failure, e.g. from constrictive pericarditis | |
| 布加综合征 | |
| Budd-Chiari syndrome |
病生理
门脉高压的直接原因主要是血管的阻力增加，但造成血管阻力增加的原因则相当多样。一般来说还会合并星状细胞及肌成纤维细胞活化。内源性血管扩张剂也可能导致静脉血流增加[2][7]。
