目的探讨皮肤软组织血管瘤的声像图和彩色血流信号特点及在血管瘤诊断中的价值。方法应用高频超声及彩色多普勒超声对23例经临床及病理证实的皮肤软组织血管瘤进行观察,包括病变的大小、位置、边界、内部回声、周边及内部的血流信号密度,脉冲多普勒判断为动脉还是静脉,测血流信号速度。结果 91.3%血管瘤边界清晰,轮廓规整,显示为局限性的实性肿物图像。小的病变以低回声为主,大的病变以混合回声为主。48%(11例)显示有彩色血流信号,其中90.1%(10例)为2岁以下的婴幼儿,以动脉血流信号为主。2岁以下儿童的血管瘤体积明显大于2岁以上儿童及成年人,病变的彩色血流信号也明显较2岁以上者丰富。成人血管瘤血流信号不丰富。大的病变较小的病变血流信号丰富。结论高频超声及彩色多普勒超声是诊断血管瘤非常有效的方法。幼儿血管瘤体积较大,多为混合回声,动脉血管丰富。病变内部丰富的动脉血管可以作为婴幼儿血管瘤的特异性诊断指标。对于成人血管瘤或进入消退期的儿童血管瘤则不适用。
Objective To investigate the characteristics of ultrasonography and color flow signals of skin and soft tissue hemangiomas and their value in the diagnosis of hemangiomas. Methods 23 cases of skin and soft tissue hemangiomas confirmed clinically and pathologically were observed by high-frequency ultrasound and color Doppler ultrasonography, including lesion size, location, boundary, internal echo, peripheral and internal blood flow signal density, Puller to determine the artery or vein, measuring blood flow signal speed. Results 91.3% of the hemangiomas had a clear boundary and a regular outline, which showed a limited solid tumor image. Small lesions with low echo, the main lesion to mix the echo-based. Color flow signals were found in 48% (11 cases), of which 90.1% (10 cases) were infants under 2 years of age with arterial blood flow signals. The volume of hemangiomas in children younger than 2 years old was significantly larger than that of children and adults aged 2 years and older. The color flow signals of lesions were significantly more abundant than those older than 2 years old. Adult hemangiomas blood flow signal is not rich. Lesions lesser lesions of large blood flow signals rich. Conclusion High-frequency ultrasound and color Doppler ultrasound is a very effective method for the diagnosis of hemangiomas. Infant hemangioma larger volume, mostly mixed echo, rich in arterial blood vessels. Abundant vascular lesions can be used as a specific diagnosis of infantile hemangiomas. Not suitable for adult hemangiomas or hemangiomas entering the regression phase.
