“…This high-energy flashlamp emitting noncoherent light and providing a wide range of various treatment parameters (wavelength, pulse duration, pulse sequences) has been used effectively in the treatment of cavernous hemangiomas, venous malformations, facial and leg telangiectasias, spider nevi, poikiloderma of Civatte, and hypertrichosis. [24][25][26][27][28][29][30] The IPLS functions are also based on the principle of selective photothermolysis.…”

Objective: The flashlamp pulsed dye laser (FLPDL) is currently the treatment of choice for port-wine stains (PWS). We recently investigated whether a non-coherent intense pulsed light source (IPLS) would be effective in the therapy of PWS. Design and Patients:In order to evaluate the efficacy in treatment of PWS (especially adult-type dark and hypertrophic), a retrospective study of 37 patients (randomly selected) with a total of 40 PWS treated with IPLS was initiated. Clinical PWS characteristics recorded were color and location of the PWS. Data collected included treatment parameters (filters, pulse duration, fluence and pulse sequencing), % clearance, and side effects (purpura, blisters, crusting, altered pigmentation and scarring).Results: Good and complete (70-100 %) clearance was achieved in 28 of 40 PWS treated with IPLS. Average number of treatment sessions in PWS reaching 100 % clearance included 4.0 for pink PWS and 1.5 sessions for red PWS. Average number of sessions in purple PWS reaching good clearance (70-99%) was 4.2 sessions. Parameters used most frequently were 515 and 550 nm cut-off-filters, pulse duration of 2.5-5.0 ms and fluences of 24 to 60 J/cm 2 . Side effects included purpura in 76%, superficial blisters in 8% and crusting in 20%. Transient pigmentation changes were seen in 10.8% of patients (hypopigmentations in 8.1%, hyperpigmentation in 2.7%). No scarring was observed. Conclusion:IPLS presents an effective and safe method for treating PWS, especially dark and facial PWS.

“…Diğer sistemler gibi en önemli yan etki hiperpigmentasyon olmuş ve vakaların %26'sında 12 haftadan sonra bile devam etmiştir 56 . Küçük çaplı damarlar IPL'e daha iyi yanıt verirler, 0.2 mm' den küçük damarlarda %90, 0,2-1 mm arası damarlarda %80 temizlenme bildirilmiştir 58 . Yüksek enerji ve kısa pulse süreleri kullanıldığında eritem, yanma, purpura, dispigmentasyon ve skarlaşma olmaktadır.…”

Özet Sum maryLaser treatment of cutaneous vascular lesions has progressed significantly over the past decades. Lasers and intense pulse light sources (IPL) are based on the principle of selective photothermolysis and can be used for the treatment of many vascular skin lesions. Light devices for vascular lesions include the 532 nm potassium titanyl phosphate laser, 577 to 595 nm pulsed dye laser, intense pulsed light devices, and 800 to 940 nm diode, 755 nm alexandrite and 1,064 nm Nd:YAG lasers. The targeted chromophore for vascular lesions is intravascular oxyhemoglobin. By properly selecting the wavelength which is maximally absorbed by the target and a corresponding pulse duration the target can be preferentially injured without transferring significant amounts of energy to surrounding tissues. Various congenital and acquired lesions can be treated such as hemangiomas, port wine stains, facial telangiectasia and leg veins. Cooling will prevent adverse effects such as pigment alteration and scar formation during therapy. A different number of repeated treatments should be done to achieve complete results of different vascular conditions. This review will discuss the different laser and light-based devices, and provide treatment approach for the management of vascular lesions. Gi riflVasküler lezyonların lazer ile tedavisi dermatoloji pratiğinde en sık uygulanan yöntemlerden birisidir. Son yıllarda lazer teknolojisindeki gelişmelere paralel olarak lazerle tedavi edilebilen vasküler lezyonların spektrumu da genişlemiş ve birçok konjenital ve akkiz vasküler lezyon farklı lazer sistemleri ile tedavi edilebilir hale gelmiştir. Selektif fototermoliz prensibi ile çalışan bu cihazlarda, hedef kromofor tarafından absorbe edilen ışınlar dokularda istenilen biyolojik etkileri ortaya çıkarırken çevre dokuların korunmasına olanak tanımakta, krutlanma, kanama veya skar oluşumu gibi istenmeyen yan etkiler daha az oluşmaktadır. İntravasküler oksihemoglobin (kırmızı lezyonlar), deoksijene hemoglobin (mavi lezyonlar) ve methemoglobin vasküler lezyonların tedavisinde hedeflenen kromoforlardır.

EinleitungBesenreiservarizen sind definiert als ständig dilatierte Gefäße, vor allem aus dem subpapillären intradermalen Venenplexus [1]. Innerhalb des Koriums sind sie vom Stratum papillare bis nahe an die Subkutis verteilt. Es handelt sich hauptsächlich um parallel zur Oberfläche verlaufende Gefäße, aber auch um absteigende venöse Arkaden (Abb. 1). ZusammenfassungEine Therapie der Besenreiser-Varikosis ist prinzipiell als kosmetische Indikation nach vorherigem Ausschluss oder Therapie einer venösen Insuffizienz indiziert. Mittel der 1. Wahl ist nach wie vor die Sklerosierungs-Therapie. Falls jedoch die Gefäßlumi-na für eine sichere Punktion zu klein sind oder die Patienten sich vor Injektionen fürchten, eine Unverträglichkeit des Sklerosierungsmittels besteht oder eine Sklerosierung bereits ohne Erfolg blieb, kann eine Laserbehandlung durchgeführt werden. Neben z. B. dem langgepulsten Farbstoff-Laser und dem frequenzverdoppelten Nd:YAG-Laser (KTP-Laser), die bei der Behandlung von Besenreisern eingesetzt wurden, führt auch der Dioden-Laser nach ca. 2-5 Behandlungen zu einer Koagulation von Gefä-ßen bis zu 1 mm Durchmesser. Vorteile gegenüber den zuerst genannten Lasern sind neben der größeren Eindringtiefe auch die geringe Größe und die Wirtschaftlichkeit des Gerätes. AbstractA cosmetic therapy of spider veins is indicated after prior exclusion or therapy of a venous insufficiency. The treatment of first choice is still the sclerotherapy. A laser-treatment can be performed if the vessels are too small for an exact puncture, the patients are afraid of injections, a sclerotherapy was not successful or an intolerance of the ingredients exists. Spider veins can be treated with the long pulsed dye-laser and the frequency-doubled Nd:YAG-laser (KTP-laser). The diode-laser also coagulates vessels up to a diameter of 1 mm after 2-5 treatments. Advantages of the diode-laser are the greater coagulation depth, the small size and efficiency of the device. Kasuistik 409Dieses Dokument wurde zum persönlichen Gebrauch heruntergeladen.
