目的探讨彩色多普勒在肝硬化合并脾功能亢进患者行部分脾动脉栓塞术前及术后的应用。方法30例肝硬化脾功能亢进患者行部分脾动脉栓塞术,治疗前后应用彩色多普勒检测脾脏大小,门、脾静脉管径及血流动力学变化,并做定量分析和对比。结果脾脏肿大程度、血流量与栓塞面积呈正相关,栓塞后门、脾静脉管径缩小(P<0.01),平均血流速度降低(P<0.01),血流量减小(P<0.01)。结论彩色多普勒能对术前病例的选择、栓塞面积大小做出指导,对术后门、脾静脉的血流动力学改变做出客观评价。
Objective To investigate the application of color Doppler before and after partial splenic arterial embolization in patients with cirrhosis and hypersplenism. Methods Thirty patients with partial hepatic cirrhosis and hypersplenism underwent splenic arterial embolization. Before and after treatment, the diameters of spleen, portal vein and splenic vein were measured by color Doppler. Hemodynamic changes were measured and compared quantitatively. Results The degree of splenomegaly and blood flow were positively correlated with the area of the embolization. The diameters of the posterior portal and splenic vein were decreased (P <0.01), the average blood flow velocity was decreased (P <0.01) and the blood flow was decreased (P <0.01). Conclusions Color Doppler can guide the choice of preoperative cases and the size of the embolization area, and make an objective evaluation on the hemodynamic changes of the posterior portal and splenic vein.
