摘要
食管曲张静脉压力测定是预测食管曲张静脉出血的最主要因素 ,食管曲张静脉的压力可在内镜下测定。 Palm er于195 1年首次报道静脉内测压 ,1982年瑞士学者 Monismann利用呼吸压力测定原理进行食管曲张静脉血管外测压。该方法不断改进 ,无创测压与直接穿刺测压的比较研究发现两者有极好的直线相关关系。目前 ,无创性食管曲张静脉测压研究仍处于实验室阶段 ,尚未获得公认 。
Variceal pressure is a strong predictor of variceal haemorrhage in patients with portal hypertension.Noninvasive variceal pressure measurement was intially described by Mosimann in 1982,Bosch have further developed this technique.In clinical study,an excellent correlation between noninvasive pressure and invasive pressure was obtained.Then,a series of hepatic hemodynamic study have been carried out from 1982 to 2000.Above all,how to measure the variceal pressure nonivasively and correctly is still an issue which need to be further studied.To diminish the variation result from variceal wall tension is most importment.
