The hemodynamics of the ultrasound (US) features of port-wine stains (PWSs) have not been reported. The purpose of this study was to evaluate the high-frequency US findings of PWSs.
We retrospectively reviewed 98 PWS cases and categorized them into 4 groups based on clinical manifestations and pathologic findings (14 nodular, 28 thickened, 52 flattened, and 4 acquired). We evaluated the US findings with 10- and 22-MHz transducers.
For nodular PWSs, the mean thickened skin ± SD was 0.6 ± 0.5 mm, and the nodule thickness was 5.7 ± 3.3 mm; 63.6% of skin lesions showed vessel density of 2.16 ± 0.93/cm with venous flow of 4.6 ± 1.1 cm/s, and all nodules showed vessel density of 6.14 ± 1.92/cm with arterial and venous flow of 26.6 ± 17.9 and 9.9 ± 5.1 cm/s, respectively. The thickened skin of the thickened type was 1.4 ± 2.7 mm; 76.5% of skin lesions showed vessel density of 3.81 ± 1.98/cm with venous flow 4.6 ± 2.1 cm/s. The thickened skin of 36 flattened lesions was 0.1 ± 0.1 mm; 91.7% of skin lesions showed vessel density of 1.08 ± 0.28/cm . The thickened skin of 4 acquired lesions was 0.7 ± 0.4 mm; 50% showed vessel density of 1.08 ± 0.28/cm . The thickened skin and vessel density of nodular and thickened PWSs were thicker and higher than those of the flattened ones. The 22-MHz transducer produced clearer contrast and higher vessel density than the 10-MHz transducer.
These results showed differences in US findings of PWSs, which may be useful for clinical diagnosis.
鲜红斑痣（PWS）超声（US）特征的血流动力学情况尚未见报道。本研究的目的是评估PWS的高频超声表现。
我们回顾性分析了98例PWS病例，并根据临床表现和病理结果将其分为4组（14例结节型、28例增厚型、52例扁平型和4例后天型）。我们使用10兆赫和22兆赫的换能器评估超声表现。
对于结节型PWS，增厚皮肤的平均厚度±标准差为0.6±0.5毫米，结节厚度为5.7±3.3毫米；63.6%的皮肤病变显示血管密度为2.16±0.93/厘米，静脉血流速度为4.6±1.1厘米/秒，所有结节显示血管密度为6.14±1.92/厘米，动脉和静脉血流速度分别为26.6±17.9和9.9±5.1厘米/秒。增厚型的增厚皮肤为1.4±2.7毫米；76.5%的皮肤病变显示血管密度为3.81±1.98/厘米，静脉血流速度为4.6±2.1厘米/秒。36例扁平型病变的增厚皮肤为0.1±0.1毫米；91.7%的皮肤病变显示血管密度为1.08±0.28/厘米。4例后天型病变的增厚皮肤为0.7±0.4毫米；50%显示血管密度为1.08±0.28/厘米。结节型和增厚型PWS的增厚皮肤和血管密度比扁平型的更厚、更高。22兆赫的换能器比10兆赫的换能器产生更清晰的对比度和更高的血管密度。
这些结果显示了PWS超声表现的差异，这可能对临床诊断有用。
