Variceal pressure is a strong predictor for a first variceal bleed in patients with cirrhosis.
To evaluate whether variceal pressure is also a determinant of the risk of a first variceal bleed in patients with non-cirrhotic portal hypertension.
Variceal pressure was measured non-invasively in 25 patients with non-cirrhotic portal hypertension and large varices while receiving a stable therapeutic regimen. Factors predictive of bleeding were compared with those observed in 87 cirrhotics.
The one year incidence of variceal bleeding was 32% (n=28) for the cirrhotic and 20% (n=5) for the non-cirrhotic patients. There was no difference in factors predicting the risk of bleeding between the groups, except for variceal pressure. For the same level of variceal pressure, the risk of variceal bleeding was lower in patients with non-cirrhotic portal hypertension. Multiple logistic regression analysis revealed the following variables as having a significant predictive power: variceal pressure (p=0.0001), red spots (p=0.004), and the time interval between the first observation of the varices and the moment of variceal pressure measurement (p=0. 0046). For the non-cirrhotics the risk of bleeding increased with higher Child-Pugh score (p=0.0024); this was not the case for the cirrhotic patients (p=0.9521).
Variceal pressure is a major predictor of variceal bleeding in patients with cirrhosis as well as in patients with non-cirrhotic portal hypertension. The risk of bleeding in non-cirrhotics is less than in cirrhotics for the same level of variceal pressure. In patients with non-cirrhotic portal hypertension the risk of variceal bleeding increases more with advancing disease.
静脉曲张压力是肝硬化患者首次发生静脉曲张出血的有力预测指标。
评估静脉曲张压力是否也是非肝硬化门静脉高压患者首次发生静脉曲张出血风险的决定因素。
对25例非肝硬化门静脉高压且伴有大静脉曲张的患者在接受稳定治疗方案期间进行无创静脉曲张压力测量。将预测出血的因素与87例肝硬化患者中观察到的因素进行比较。
肝硬化患者静脉曲张出血的一年发生率为32%(n = 28),非肝硬化患者为20%(n = 5)。除静脉曲张压力外,两组之间预测出血风险的因素没有差异。对于相同水平的静脉曲张压力,非肝硬化门静脉高压患者发生静脉曲张出血的风险较低。多因素逻辑回归分析显示以下变量具有显著预测能力:静脉曲张压力(p = 0.0001)、红点(p = 0.004)以及首次观察到静脉曲张至测量静脉曲张压力的时间间隔(p = 0.0046)。对于非肝硬化患者,出血风险随Child-Pugh评分升高而增加(p = 0.0024);肝硬化患者则不然(p = 0.9521)。
静脉曲张压力是肝硬化患者以及非肝硬化门静脉高压患者静脉曲张出血的主要预测指标。对于相同水平的静脉曲张压力,非肝硬化患者的出血风险低于肝硬化患者。在非肝硬化门静脉高压患者中,静脉曲张出血风险随疾病进展增加得更多。
