超声诊断在评价门腔静脉分流术后门静脉血流动力学中的研究价值
The Value of Ultrasonography in Detection of Hemodynamic Changes in Portal System before and after Direct Intrahepatic Portacaval Shunt
摘要
Abstract
Objective To investigate the hemodynamic changes of portal vein system in portal hypertension before and alter direct intrahepatic portacaval shunt(DIPS), and evaluate the clinical value of ultrasonography. Methods The vessel diameter, flow direction, flow velocity and pressure changes of main portal and portal branches were compared on ultrasonography and angiography among 12 patients pre- and post-DIPS. Results Technical successes were achieved in all 12 patients; The hepatofugal flow was detected through the stent, and no leakage was detected around it; Hie diameter of the main and right branch of portal vein, splenic vein and superior mesenteric vein were narrow after procedure than those before DIPS (P<0.05), while no significant change was observed in the left branch of portal vein (P>0.05). The blood flow velocity of portal vein system increased (P<0.01). Conclusion DIPS can reduce portal pressure by diverting blood flow of Portal system to inferior vena cava. As the first choice to observe the hemodynamic changes and evaluate the stent function, ultrasonography is helpful as the evidences for surgical treatment.关键词
