摘要
目的探讨彩色多普勒超声在部分脾栓塞术(PSE)中的应用价值。方法36例患者行PSE治疗,分别于栓塞术前1周内,栓塞后1-6周及2-6个月行彩色多普勒超声检查。观察脾脏大小,门静脉及脾静脉的内径、血流参数,了解栓塞区回声变化及外周血象变化,分析结果判断疗效。结果PSE 2个月后脾脏开始萎缩变小,6个月后显著性缩小;栓塞区的脾实质内无动静脉血流信号;栓塞后门静脉及脾静脉的血流速度明显减慢,血流量显著性减少;术后2 -6个月门静脉及脾静脉内径显著性缩小;外周血象明显改善。结论彩色多普勒超声可作为评价PSE临床疗效的客观依据之一。
Objective To investigate the application value of partial spleen embolism （PSE） with color Doppler flow imaging （CDFI）. Methods Thirty-six patients were all treated by PSE, and the size of spleen and the inner-diameter of portal vein and spleen vein, the parameter of blood stream, the change of embolism echo were detected with color Doppler uhrasonography one week before PSE, 1～6 weeks and 2～6 months respectively after PSE. Results two months after PSE the spleens began to atrophy and diminish, and after six months the spleens dwindled observably; there is no signal of blood stream of artery and vein in essence of spleen, the flow velocity of portal vein and spleen vein were lower and there was a significant decrease in their blood flow volume, and the inner-diameter of portal vein shrink remarkably. Conclusion Color Doppler uhrasonography is one of the objective indexes that estimate the clinical curative effects of PSE.
