This study tests two types of lasers (ND YAG 1064 short and ultra-short pulses) to treat hyperchromic skin lesions secondary to venous hypertension (stasis dermatitis)
Background: Stasis dermatitis with hyperpigmented skin lesions is a serious health problem for patients with chronic venous hypertension. Although no randomized studies have evaluated lasers for this treatment, lasers can be an attractive option.
Methods: This prospective, randomized, 3-arm, open-label, vehicle-controlled study will enroll patients scheduled to undergo treatment for stasis dermatitis with hyperpigmented skin lesions. Patients will be allocated to either Nd: YAG 1064 nm short pulse laser-nanoseconds (group 1), or Nd: YAG 1064 nm ultra-short-pulse laser-picoseconds (group 2), or cold cream vehicle control (group 3). All treatments are scheduled for 6 visits with pre-defined dates, with a final follow-up visit at intervals of 28 to 35 days. Primary outcomes include colorimetry analysis, secondary outcomes pre- and post-photographic analysis, and DLQI quality-of-life assessment.
Conclusions: The results of this trial will provide high-quality evidence to guide clinical practice on optimal management of hyperpigmented skin lesions secondary to stasis dermatitis.

| short-pulse ND: YAG 1064 laser | Procedure | Nd: YAG 1064 nm short pulse laser (5 nanoseconds), 4 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Smart, a Q-Switch Laser produced by Medical San (Lajeado, RS, Brazil). |
| Measure | Description | Time Frame |
|---|---|---|
| Colorimetry | The skin tone dissimilarity (expressed as ΔE) at treated and adjacent areas measured with digital calorimetry. The ΔE value derives from the differences in the International Commission on Illumination L*a*b* (CIELAB) color space. It is a structured approach to quantifying color differences, with specific intervals indicating varying levels of perceptibility with different intensities of pigmentation:

| Measure | Description | Time Frame |
|---|---|---|
| Photographic analysis | The co-primary outcome will be the incidence of post-procedure skin hyperpigmentation improvement after six treatment sessions, evaluated through before-and-after photo documentation analysis by three experienced, independent, and blind observers. All the evaluators will have access to high-definition before-and-after pictures of the patient's legs that were designated for them. Then, according to their expertise, they will answer the question, "Do you think there's post-treatment improvement in hyperpigmentation in the treated areas of this limb, yes or no?" for the affected limb. The answers chosen by most of the evaluators will be considered for data analysis. |
| Measure | Description | Time Frame |

| DLQI - quality-of-life | The DLQI will be applied in the baseline and final visits and includes 10 questions:
