目的探讨高频彩色多普勒超声对上肢血管瘤诊断和治疗的指导价值。方法对2006年7月至2009年3月收治的12例上肢血管瘤应用日本产Aloka SSD prosoundα10型高频彩色多普勒超声进行检查,并对9例患者予以手术治疗。手术后3周进行复诊观察手术效果。结果对9例患者进行了手术治疗,高频彩色多普勒超声显示与手术所见完全相符。二维超声显示:肿瘤平均大小6.6cm×4.0cm,形态不规则,与周围组织分界不清,内为不规则低无回声暗区,似“蜂窝”状,可见扩张的血管或血窦内血栓形成及钙化,呈现强回声,后方有声影,压迫肿物或者变换体位时肿物可以增大。彩色多普勒见有丰富的血流信号,血流Alder分级均为Ⅲ级,异常血流区域平均大小7.2cm×5.0cm,比较二维超声范围增大。压迫肿物可见暗区扩张,血流信号增多。结论高频彩色多普勒超声对上肢血管瘤的定性及准确的定位诊断、侵袭范围以及对术中指导和手术后疗效的评价具有重要的临床价值。
Objective To investigate the value of high-frequency color Doppler ultrasound in the diagnosis and treatment of upper limb hemangiomas. Methods 12 cases of upper extremity hemangiomas from July 2006 to March 2009 were examined by Japanese Aloka SSD prosoundα10 high frequency color Doppler ultrasound and 9 cases were treated surgically. Three weeks after surgery, follow-up was performed to observe the effect of surgery. Results Nine patients underwent surgical treatment. High-frequency color Doppler ultrasound showed complete agreement with the surgical findings. Two-dimensional ultrasound showed: the average size of the tumor 6.6cm × 4.0cm, irregular shape, with the surrounding tissue unclear boundaries, irregular low echo-free dark areas, like “honeycomb ” shape, showing the expansion of blood vessels or sinusoids Thrombosis and calcification, showing a strong echo, the back of the sound shadow, oppression of the tumor or change the position when the tumor can increase. Color Doppler see a rich blood flow signal, blood flow Alder grading are grade Ⅲ, the average size of abnormal blood flow area 7.2cm × 5.0cm, compared with two-dimensional ultrasound range increases. Compression mass visible dark area expansion, increased blood flow signals. Conclusion High-frequency color Doppler ultrasonography of upper limb hemangiomas qualitative and accurate positioning diagnosis, invasion range and evaluation of intraoperative guidance and postoperative efficacy has important clinical value.
