Sclerotherapy is a widely used method for the obliteration of blood vessels. Hyperpigmentation is a frequent complication that results from haemosiderin (FeO) accumulation. Hyperpigmentation and changes in the skin can be observed with ultrasound.
The aim of this study was to evaluate the efficacy of hyperpigmentation elimination using an intense pulse light generator (IPL) equipped with radio waves (RF) under ultrasonography (US) control.
Twenty-one women with permanent hyperpigmentation (after sclerotherapy or crossectomy combined with sclerotherapy) underwent a hyperpigmentation eliminating therapy with the use of IPL + RF and were monitored by using US. The thicknesses of the dermis and the subcutaneous tissue as well as the echogenicities of each layer were assessed.
As a result of the therapy, a complete regression of hyperpigmentation was achieved in 90.48% of the women, and in 9.52% of the women, the therapy led to a reduction in hyperpigmentation but did not cause its complete disappearance. An increase in dermal echogenicity and a decrease in subcutaneous tissue echogenicity were observed, but there was no change in their thicknesses. After the therapy, the ultrasound images of areas of previous hyperpigmentation corresponded with images that were characteristic of healthy skin.
IPL + RF therapy is effective for eliminating permanent skin hyperpigmentation after sclerotherapy. US is also useful in this therapeutic method.
硬化疗法是一种广泛应用于血管闭塞的方法。色素沉着是一种常见的并发症,是由于铁蛋白(FeO)积累引起的。超声可以观察到色素沉着和皮肤变化。
本研究旨在评估在超声(US)控制下使用配备无线电波(RF)的强脉冲光发生器(IPL)消除色素沉着的疗效。
21 名女性因硬化疗法或交叉切除术联合硬化疗法后出现永久性色素沉着接受了 IPL + RF 色素沉着消除治疗,并通过 US 进行监测。评估了真皮和皮下组织的厚度以及各层的回声强度。
治疗后,90.48%的女性完全消退了色素沉着,9.52%的女性治疗后色素沉着减轻,但未完全消退。真皮回声强度增加,皮下组织回声强度降低,但厚度无变化。治疗后,先前色素沉着区域的超声图像与健康皮肤的特征性图像相对应。
IPL + RF 治疗对硬化疗法后永久性皮肤色素沉着有效。US 在这种治疗方法中也很有用。
