目的比较用于四肢软组织静脉畸形的各影像学检查方法的临床价值。方法  收集2009年2月-2014年2月于我院就诊的27例四肢软组织静脉畸形患者，所有患者均行X线平片、超声、CT、MRI及血管造影检查，并对各检查结果进行统计描述，比较各检查的优缺点。结果 四肢软组织静脉超声检查可表现大小不等、分布不均、形状不规则的蜂窝或网状液性暗区，软组织中的畸形静脉多表现为可压缩的低回声，明确病变畸形静脉的形态、大小以及范围，并可用于术中动态观察，但该检查方式的病变界限欠清。而MRI检查能够清楚分辨畸形静脉的部位、大小。定位准确，明确病变血管累及范围，并能明确软组织成分，虽相对较昂贵，但对于静脉畸形的诊断有重要的指导意义。结论  MRI以及超声检查对于畸形血管的诊断以及明确病变范围有重要的临床指导意义，值得临床推广及应用。

Objective To compare the clinical value of each imaging modality in extremity soft tissue malformations. Methods 27 patients with extremity soft tissue malformations in our hospital from February 2009-February 2014 were selected; all patients were treated by ray, ultrasound, CT, MRI and angiography, and descriptive statistics the examination results, to compare the advantages and disadvantages of each inspection. Results Extremity soft tissue venous ultrasound examination may show varying sizes, uneven distribution of irregularly shaped cellular or mesh liquid dark area, soft-tissue venous malformations showed more compressible hypoechoic, morphological lesions clear vein malformation, size, and range, can be used for intraoperative dynamic observation, but the boundaries of the lesion is less clear way of checking. MRI examination can clearly distinguish venous malformation location, size, positioning accuracy, clear vascular lesions involving the scope,clear soft tissue components, although relatively expensive, but for the diagnosis of venous malformations has important guiding significance. Conclusion MRI and ultrasound for the diagnosis of vascular malformations and lesions clearly has important clinical significance, it's worthy of being applied in clinic.
