![]() ![]() While analyzing the full sample, researchers determined that the only independent variable with statistical significance was the treatment device. Researchers sought a primary endpoint of at least 50% improvement in lesion appearance. These photographs were each assessed by blinded graders the analyses determined the degree of PWB improvement using a 1 to 5 analog scale-with 1 representing poor improvement and 5 representing complete, 100% improvement.ĭuring inclusion, researchers also collected patient data, including: Participants (n=160) had been treated either with the NPDL (n=80) or PPDL 595-nm (n=80) devices at one of two treatment sites and had to be accompanied by follow-up photographs. Researchers collected data from patients with PWBs between 2011 and November 2021. They cited the tendency of heterogenous ectatic vessels to remain untreated or improperly treated if not addressed in infancy as well as research supporting the efficacy of NPDLs in treating photoaging, poikiloderma, and rosacea. All this means is that the patient will need a ‘maintenance’ treatment every few years in order to keep the desired effect.In a retrospective study 1 and comparative analysis, researchers sought to compare treatment parameters and outcomes in patients whose PWBs were treated using either the prior generation pulsed dye laser (PPDL) or the larger spot NPDL. Since laser treatment is aimed at the effect and not the cause of portwine stains, it stands to reason that the lesion will eventually return. One of the controversies concerns the recurrence of portwine stains after treatments. We usually space treatments 6 – 8 weeks apart during the first few treatments but, as the treatment advances, the interval between treatments increases to 3 months and eventually 6 months. The timing of the interval between treatments is arbitrary. It will usually take between 6 and 10 treatments to get maximum lightening. Upper arm lesions do better than the lower part of the arm. Shoulder and upper chest lesions do well. Central cheek portwine stains fare worst of all facial portwine stains. Forehead and eyelid lesions also do well, as do temple lesions. ![]() Some areas appear to do much better than others. ![]() The very first treatment seems to be the most important, especially when dealing with a young child. The younger the child the more efficacious the treatment. Geographic, nonconfluent portwine stains do much better than confluent portwine stains.This does not mean that confluent portwine stains will not do well. Only a small percentage of portwine stains will disappear with treatment (10-12 %). The rate of complications is extremely low and in the vast majority of cases, the portwine stain should lighten significantly with treatment. Once again, an experienced physician is always desirable. Almost all lasers these days have some sort of cooling device. The standard of care at this point in time involves the use of a Pulsed Dye Laser. Port wine stains were amongst the first lesions to be successfully treated by lasers. Every case is different, but we hope that it helps to see photos that might be representative of what your child is experiencing. ![]() Some of the patients are still having treatments and their photos will be updated after future procedures. We have compiled as many before and after photos of our patients to show some of the results that we have achieved.
