鲜红斑痣是一种常见的先天性毛细血管畸形.多年来脉冲染料激光仍是治疗鲜红斑痣的金标准,然而皮损完全清除的患者却很少,部分患者在接受脉冲染料激光治疗达到一定程度后,对脉冲染料激光治疗产生抵抗.抵抗性鲜红斑痣给患者造成心身损害,因此,进一步改善皮损症状对皮肤美容医师仍具有挑战性.难治性鲜红斑痣治疗方法最新进展,主要包括改良的脉冲染料激光、光动力疗法、脉冲染料激光+光动力疗法以及脉冲染料激光+血管扩张抑制剂的联合应用. 相似文献

The flashlamp-pumped pulsed dye laser (FPDL) is regarded as the gold standard in the treatment of port wine stains. The purpose of this prospective, intra-individual, comparative clinical study was to investigate whether a frequency-doubled variable pulsed Nd:YAG laser (frequency-doubled Nd:YAG) is equally as safe and effective as established lasers. Forty-three patients with port wine stains were included in the study. Test treatments were performed using the frequency-doubled Nd:YAG laser (532 nm; 4 mm psi; 5-50 ms; 5.5 to 15 J/cm2) versus the FPDL (585 nm; 450 micros; 7 mm psi; 6 J/cm2). After 6 weeks, a full lesional treatment was performed using the device and the parameters showing the best clearance and the fewest side effects. The clearance of the lesions was generally good to fair. With the exception of poor results at 5 ms and 5.5 J/cm2 with the frequency-doubled Nd:YAG laser, there were no significant differences between the two laser devices. Scar formation, nevertheless, occurred in only 3% of the FPDL-treated sites versus up to 18% of the frequency-doubled Nd:YAG sites, increasing with pulse duration. In port wine stains, the FPDL remains the therapy of choice because of the somewhat better results and a lower frequency of side effects, especially scarring. 相似文献

Five years' experience of treating port wine stains with the flashlamp-pumped pulsed dye laser 总被引:1,自引:0,他引:1
Summary During the last 5 years, 640 patients had treatment to their port wine stains (PWS) with a flashlamp-pumped pulsed dye laser. One hundred and fifty-six patients have been discharged for varying reasons, of which 59 (38%) achieved excellent (at least 75%) lightening of their birthmark. Of the remaining patients, those who attended the clinic for the sixth and 12th time for treatment were also assessed to determine the degree of fading achieved in the port wine stain. Our findings confirm that flashlamp-pumped dye laser treatment is safe and effective for the treatment of PWS and that complications are rare. However, the degree of fading achieved is variable and often unpredictable. Fifty-two per cent of facial lesions of different colours achieved over 75% fading as against 18% of non-facial lesions. Sixty-four per cent of those over the age of 50 years had an excellent response whereas only 19% of those below the age of 5 years were able to achieve a similar result. The colour of the port wine stain was found to be of no prognostic value. A search for an accurate and non-invasive method to predict the outcome of flashlamp-pumped pulsed dye laser therapy for PWS is warranted. 相似文献

Pediatric vascular lesions can be medically threatening and psychologically distressing to patients. This article reviews literature on the laser treatment of two common pediatric vascular lesions, port wine stains and hemangiomas. The purpose of this report was to distinguish the lesions from one another and to present the advantages, disadvantages, complications, and limitations of laser treatment for each lesion type. This review is not a comprehensive inventory but instead highlights the studies that best show promising results or the limitations of laser treatment for the lesions. Overall, port wine stain laser treatment promoted notable clearing with low side effects, whereas hemangioma laser treatment provided inconsistent benefits and severe side effects occasionally. Laser treatment of port wine stains is safe and effective, but laser treatment of hemangiomas remains controversial and is best for lesions without deeper components. 相似文献

目的:比较532 nm KTP激光与脉冲染料激光(PDL)对鲜红斑痣的疗效及安全性。方法:将18例鲜红斑痣患者的自身皮损随机分成KTP激光治疗区及PDL治疗区,分别予以532 nm KTP激光及595 nm PDL治疗,每2~3个月治疗一次,共2~4次。每次治疗前、后即刻及治疗后2~3个月对患者激光治疗后的皮损进行疗效及安全性评价。结果:532 nm KTP激光治疗组及595 nm PDL治疗组治疗后疗效均无显著差异。在一些既往曾接受PDL治疗疗效不佳的患者,经532 nm KTP激光治疗后,皮损取得一定改善。532 nm KTP激光治疗组在治疗时疼痛程度及治疗后紫癜程度均显著低于595nmP DL治疗组。两组均有1例色素沉着发生。结论:532 nm KTP激光治疗鲜红斑痣的疗效较好,不良反应少,安全性好,可以作为鲜红斑痣治疗的另一方案。 相似文献

Nineteen patients are presented with acquired port wine stains. Acquired port wine stains are uncommon vascular lesions with the appearance of a congenital port wine stain but onset after birth. This is the largest group of patients reported to date. The acquired port wine stain was on the head and neck in 17 patients and in six this was associated with preceding trauma. Psychological assessments in adult patients showed similar morbidity to that seen in patients with congenital port wine stains. This morbidity was improved with successful laser treatment. Pulsed dye laser therapy resulted in complete clearance of the lesion in six (46%) of 13 patients treated. Two further patients had an excellent response. 相似文献

BACKGROUND: Various lasers, particularly the flashlamp-pulsed dye laser, have been proven to be effective in the treatment of facial vascular lesions. Nevertheless, the post-treatment side effects, such as pronounced purpura and changes in pigmentation, have been a matter of concern to patients. OBJECTIVE: To test the efficacy of an alternative treatment option that uses intense pulsed light to provide patients with a more tolerable post-treatment outcome. METHODS: A total of 200 patients were treated with an intense pulsed light source (PhotoDerm ® VL) using various treatment parameters. The patients were treated for facial veins (primarily telangiectasia), facial hemangiomas, rosacea and port wine stains. RESULTS: Of the 188 patients who returned for follow-up after 2 months, 174 achieved 75% to 100% clearance in one to four treatment sessions. The post-treatment side effects were minimal and well tolerated by the patients. There were no instances of scarring or other permanent side effects. CONCLUSION: The PhotoDerm ® VL provides a highly effective and safe alternative to the laser for treatment of facial vascular lesions. The device may achieve improved results for lesions that are resistant to laser therapy. The rate and degree of cosmetic side effects are considerably less than with laser treatment. 相似文献

The pulsed tunable dye laser is the established treatment for facial port wine stains (PWSs), particularly in children. There have been very few studies specifically addressing the efficacy of this laser in the treatment of lower limb PWSs. Twenty-seven patients with lower limb PWSs have been treated with the Candela pulsed tunable dye laser. Seventeen patients have been discharged; one patient had greater than 95% clearance of the naevus and three others had a good response to treatment. Ten patients who are continuing treatment have had an average of 9:4 treatments. Only one patient has achieved a good result, and none an excellent result. These results are disappointing compared with published figures for outcome following pulsed tunable dye laser treatment to facial PWSs, and confirm the clinical impression that PWSs on the lower limb do not respond well to pulsed dye laser therapy. 相似文献

We report on 901 patients with port wine stains treated by means of an argon laser. The treatment results have been definitively evaluated in 371 patients. They were significantly influenced by the patients' age and by the colour of the lesions. The worst response to the therapy was seen in pink port wine stains in children and juvenile patients (20% good results), in contrast to red and purple lesions in adult patients (80% excellent and good results). The size of the port wine stains did not significantly influence the treatment results, but in extensive lesions homogeneous lightening could not usually be attained and treatment often extended over some years. Port wine stains in the head and neck area responded best to therapy, and lesions on the legs, worst. Altogether, in 60%-70% of adult patients excellent or good results were obtained, the lesions being completely removed or significantly lightened and reduced in size. The side-effects of laser therapy were scar formation (7.3%) and changes in pigmentation (8.6%). 相似文献

Sixty-two patients with port wine stains completed a questionnaire related to their flashlamp-pumped pulsed tunable dye laser treatment. The treatment wtis well tolerated by the majority. Forty-eight per cent of patients experienced some weeping or crusting after treatment. The major cause of morbidity was protracted bruising following treatment, and this caused a significant restriction of activities in 45% of patients. 相似文献
