目的 评价肝硬变病人行部分脾栓塞术 (PSE)前后门脉血流动力学变化。方法 应用多普勒彩超检测 2 2例肝硬变门静脉高压病人经PSE前后门脉系统血流动力学变化。结果 PSE后门脉血流量、脾静脉血流量、肠系膜上静脉血流量及内脏血流量均下降。结论 多普勒彩超测肝硬变病人的门脉血流动力学变化为PSE选择病例及判断疗效提供临床依据 ,PSE可改善门脉高动力循环状态。
Objective To evaluate the changes of portal hemodynamics in patients with cirrhosis before and after partial splenic embolization (PSE). Methods Doppler ultrasound was used to detect the changes of hemodynamics in portal vein before and after PSE in 22 patients with cirrhotic portal hypertension. Results The posterior portal blood flow, splenic venous blood flow, superior mesenteric vein blood flow and visceral blood flow decreased after PSE. Conclusions The changes of portal hemodynamics in patients with cirrhosis by Doppler echocardiography provide the clinical evidence for selecting patients and judging the efficacy of PSE. PSE can improve the portal hyperdynamic circulation.
