Height of portal pressure correlates with severity of alcoholic cirrhosis. Portal pressure indices are not however used routinely as predictors of survival.
To examine the clinical value of a single portal pressure measurement in predicting outcome in cirrhotic patients who have bled.
A series of 105 cirrhotic patients who consecutively underwent hepatic venous pressure measurement were investigated. The main cause of cirrhosis was alcoholic (64.8%) and prior to admission all patients had bled from varices.
During the follow up period (median 566 days, range 10-2555), 33 patients died, and 54 developed variceal haemorrhage. Applying Cox regression analysis, hepatic venous pressure gradient, bilirubin, prothrombin time, ascites, and previous long term endoscopic treatment were the only statistically independent predictors of survival, irrespective of cirrhotic aetiology. The predictive value of the pressure gradient was much higher if the measurement was taken within the first or the second week from the bleeding and there was no association after 15 days. A hepatic venous pressure gradient of at least 16 mm Hg appeared to identify patients with a greatly increased risk of dying.
Indirectly measured portal pressure is an independent predictor of survival in patients with both alcoholic and non-alcoholic cirrhosis. In patients with a previous variceal bleeding episode this predictive value seems to be better if the measurement is taken within the first two weeks from the bleeding episode. A greater use of this technique is recommended for the prognostic assessment and management of patients with chronic liver disease.
门静脉压力高度与酒精性肝硬化的严重程度相关。然而,门静脉压力指标并未常规用作生存预测指标。
探讨单次门静脉压力测量对肝硬化出血患者预后的预测临床价值。
对连续接受肝静脉压力测量的105例肝硬化患者进行了研究。肝硬化的主要病因是酒精性(64.8%),入院前所有患者均有静脉曲张出血。
在随访期间(中位时间566天,范围10 - 2555天),33例患者死亡,54例发生静脉曲张出血。应用Cox回归分析,无论肝硬化病因如何,肝静脉压力梯度、胆红素、凝血酶原时间、腹水和既往长期内镜治疗是仅有的具有统计学意义的独立生存预测指标。如果在出血后的第一周或第二周内进行测量,压力梯度的预测价值要高得多,15天后则无相关性。肝静脉压力梯度至少16 mmHg似乎可识别出死亡风险大幅增加的患者。
间接测量的门静脉压力是酒精性和非酒精性肝硬化患者生存的独立预测指标。对于既往有静脉曲张出血发作的患者,如果在出血发作后的前两周内进行测量,这种预测价值似乎更好。建议更多地使用该技术对慢性肝病患者进行预后评估和管理。
