摘要
应用彩色多普勒血流显像(CDFI)对35例肝硬化患者21例扩张的胃冠状静脉血流动力学进行研究,对其中18例进行了术中冠状静脉及门静脉测压。结果发现;肝硬化冠状静脉压力比正常明显升高(P<0.01),并约有三分之一的冠状静脉压力明显高于门脉主干压力(P<0.05),冠状静脉压力与其扩张的程度、血流速度及血流量均有很好的相关性,胃冠状静脉压力升高是食道静脉曲张的主要原因,对胃冠状静脉的彩色多普勒血流显像可估测其压力程度及上消化道出血的可能性。
The hemodynamics of 21 dilated coronary vein was studied in 35 patients with liver cirrhosis by means of Color Doppler Flow Imaging(CDFI), the portal venous pressure (PVP) and coronary venous pressure(CVP) of 18 patients were measured intraoperatively. The results showed that CVP was significantly increased in cirrhosis patients (P<0.05)。 Significant correlation was found among CVP, diameter of vessels, blood velocity, blood flow in dilated coronary vein. The hyperdynamic blood pressure in coronary vein was a principal factor in the formation of gastroesophageal varices. CDFI can be used for the evaluation of coronary vein pressure and the risk of gastrointestinal bleeding,
