【摘要】 目的探讨二维及彩色多普勒超声在评价新型栓塞剂海藻酸钠微球(KMG)用于子宫动脉栓塞(UAE)治疗子宫肌瘤近期疗效中的价值。方法49例子宫肌瘤患者在应用KMG经UAE术前3～7d及其后1、3、6个月进行二维及彩色多普勒超声检查,观察其二维声像图、血流动力学变化。结果栓塞6个月后肌瘤体积明显缩小(缩小35%～90%),早期瘤内回声明显增强,后出现液性暗区、钙化等改变,术后肌瘤内血流完全消失。结论KMG是一种有效的用于UAE治疗子宫肌瘤的栓塞剂,而超声对评价其效果、不良反应及术后的长期随访具有重要价值,是无创性检查的首选方法。更多还原

【Abstract】 Objective To explore the effectiveness of a new kind of embolization agent-sodium alginate(KMG), and to evaluate the clinical value of 2D color Dopper ultrasound in assessing the therapeutic effect of uterin arterial embolization (UAE) in leiomyomas. Methods Forty nine patients with symptomatic leiomyomas were undertaken UAE with KMG for the treatment. Sonography was performed at 3 ～ 7 days before and,1,3,6 months after UAE with 2D color Doppler for evaluating the 2D echograms and hemodymamics. Results Forty nine leiomyomas were studied after UAE,showing a marked reduction in the size(35% - 90%). No blood flow was demonstrated in the leiomyomas either 3 - 7 days or 1 month or 3 months after the procedurc. The reappearance of blood flow could be seen in only one case. Conclusion KMG is an efficient embolization agent for the treatment of symptomatic leiomyomas with UAE,and ultrasonography is a useful tool to assess the effectiveness.
