摘　　要：目的 探讨葡萄酒色痣（PWS）的超声特征及其诊断价值。方法 收集上海交通大学医学院附属第九人民医院2015年1月至2016年1月经病理或临床证实并经超声检查的PWS患者128例（病灶162处）。根据超声表现，将PWS分为平坦型、增厚型、结节型，对其超声特征进行回顾性分析。结果 平坦型PWS患者共95例，病灶118处，病灶处皮肤层厚度显著高于相应健侧，但两者厚度差异主要在0.2 mm以下；低回声79处（67%），未见血流信号75处（64%），测及静脉频谱15处，峰值（3.33 ± 1.80） cm/s。增厚型PWS患者17例，病灶24处，病灶处皮肤层厚度（1.80 ± 0.70） mm，亦显著高于相应健侧［（1.14 ± 0.43） mm］，差异有统计学意义（t = 6.834，P 〈 0.001）；病灶低回声24处（100%），不丰富血流信号15处（62%），测及静脉频谱18处，峰值（6.61 ± 3.87） cm/s。结节型PWS患者16例，病灶20处，病灶厚度（6.45 ± 4.68） mm，低回声18处（90%），丰富血流信号15处（75%），测及静脉频谱15处，峰值（10.00 ± 5.39） cm/s，动脉频谱19处，收缩期峰值（24.58 ± 13.82） cm/s，阻力指数0.59 ± 0.13。增厚型和结节型PWS皮损厚度显著高于平坦型（均P 〈 0.05），结节型显著高于增厚型（P 〈 0.05）；3型静脉峰值亦各不相同（F = 10.630，P 〈 0.001），且增厚型和结节型PWS皮损静脉峰值显著高于平坦型（均P 〈 0.05），而结节型与增厚型差异无统计学意义（P 〉 0.05）。结论 超声对PWS的诊断具有一定的价值。Objective To investigate ultrasound features of port-wine stains （PWS）, and to evaluate the diagnostic value of ultrasound imaging. Methods A total of 128 patients with pathologically or clinically confirmed PWS （162 lesions）, who were also subjected to ultrasound examination, were collected from Shanghai Ninth People′s Hospital affiliated to Shanghai Jiao Tong University School of Medicine between January 2015 and January 2016. According to ultrasound findings, these PWS lesions were divided into 3 types： flat type, hypertrophic type and nodular type, and the ultrasound features were retrospectively analyzed. Results For 95 patients with flat PWS （118 lesions）, the skin thickness was significantly higher in the lesion areas than in the normal areas, but most of the thickness difference was less than 0.2 mm. Of the 118 lesions, 79 （67%） showed hypoechoic areas, 75 （64%） showed no blood flow signal, and the vein spectrum was detected in 15, with a peak of （3.33 ± 1.80） cm/s. For 17 patients with hypertrophic PWS （24 lesions）, the lesion areas showed significantly increased skin thickness compared with the normal areas （1.80 ± 0.70 mm vs. 1.14 ± 0.43 mm, t = 6.834, P 〈 0.001）. All （100%） of the 24 lesions showed hypoechoic areas, low blood flow signals were observed in 15 （62%）, and the vein spectrum was detected in 18 lesions, with a peak velocity of （6.61 ± 3.87） cm/s. For 16 patients with nodular PWS （20 lesions）, the skin thickness in the lesion areas was （6.45 ± 4.68） mm. Of the 20 lesions, 18 （90%） showed hypoechoic areas, and abundant blood flow signals were observed in 15 （75%）. Additionally, the vein spectrum was detected in 15 lesions, with a peak velocity of （10.00 ± 5.39） cm/s, and the artery spectrum was detected in 19 lesions, with a systolic peak velocity of （24.58 ± 13.82） cm/s and a resistance index of 0.59 ± 0.13. The skin lesions was significantly thicker in the hypertrophic PWS group and nodular PWS group than in t
