心内平滑肌瘤病的彩色多普勒血流成像诊断

Color Doppler flow imaging in diagnosis of intracardiac leiomyomatosis

目的认识心内平滑肌瘤病(ICL)的彩色多普勒血流成像(CDFI)图像特点,探讨CDFI诊断ICL的临床应用价值。方法采用HP5500彩色多普勒超声仪分别对7例心内平滑肌瘤病患者进行心脏、下腔静脉和髂静脉检查,观察静脉内和心内平滑肌瘤病的超声图像特点,并与手术病理结果比较。结果7例患者超声图像均显示右心内随心动周期漂浮样运动的网格状或实质性的肿物回声,并与下腔静脉和/或髂静脉内的肿物回声相连,诊断为心内平滑肌瘤病。4例患者行手术治疗,病理结果与超声结果一致。结论彩色多普勒血流成像技术可为准确诊断心内平滑肌瘤病提供重要的信息,有广泛的临床应用价值。

Objective To recognize the ultrasound characterizations of intracardiac leiomyomatosis （ICL）, and discuss the value of color Doppler flow imaging （CDFI） in diagnosing ICL. Methods Seven patients with ICL were examined with color Doppler flow imaging. The characteristics of the heart, inferior cave vein, and iliac vein on CDFI were observed and compared with those of surgery. Results A large, freely mobile, filamentous cast appearing in the right atrium was demonstrated in all of patients. The cast extended from the dilated inferior cave vein into the right atrium, and the inferior cave vein, common iliac vein, internal iliac vein were also filled with free-floating cast. Four patients underwent surgery, and the pathological results were correlated with CDFI. Conclusion CDFI provides important information on location and extension of the leimyomatosis in the patients with ICL.
