彩色多普勒超声对Parkes-Weber综合征的诊断

Diagnosis of Parkes-Weber syndrome by color doppler ultrasound

目的探讨彩色多普勒超声对Parkes-Weber综合征（PWS）的诊断价值。方法回顾性分析首都医科大学附属北京安贞医院经临床和影像学检查确诊的21例PWS患者彩色多普勒超声检查资料，对其动静脉病变进行比较。结果超声检查发现PWS患者下肢皮肤的葡萄酒色血管痣或血管瘤21例（100．0％）；患肢增粗、增长21例（100．0％）；超声发现浅静脉曲张和深浅静脉发育不良及畸形20例（95．2％），发育不良静脉管径明显小于同名动脉。超声对动静脉瘘口显示率为78．0％（32／41），为多发动静脉瘘，瘘口处可见花色血流信号，瘘口近心段静脉管径相对较粗，伴流速增高，呈动静脉混合频谱。结论彩色多普勒超声是PWS初步诊断及监测的最佳无创检查方法。

Objective To evaluate the diagnostic value of color doppler ultrasound of Parkes-Weber syndrome （PWS）. Methods We retrospectively analyzed results of color doppler ultrasound examination of 21 cases of PWS diagnosed by clinical and imaging methods in our hospital and lesions of arteries and veins were compared. Results Lower extremity ultrasound examination revealed wine-colored skin vascular nevi or hemangioma and thickening of the involved limb in 21 of the PWS patients （ 100.0% ） ; lower extremity ultrasound examination revealed varicose of the superficial veins and dysplasia and malformations of the deep and superficial veins in 20 of the PWS patients （95.2%） ;the diameter of the dysplasia veins were significantly less than artery accompanied. 78.0% （32/41） orifice of arteriovenous fistula cases could be revealed by ultrasound. The arteriovenous fistula were multiple. Color flow signals could be seen in the orifice of the fistula, diameter of the proximal segment of the vein near the orifice vein dilated and flow rate increased with mixed arteriovenous doppler spectrum. Conclusion Color doppler uhrasound is the best noninvasive examination methods for preliminay diagnosing and monitoring PWS.
