Abstract
- Background: Pulsed dye lasers (PDLs) are well-established for treatment of capillary malformations but are unable to penetrate the depth needed to treat deeper vascular lesions. A combined approach using a deeper penetrating wavelength with a "superficial" wavelength could more comprehensively treat vascular malformations than PDL alone.<br />Objective: To evaluate the safety and efficacy of the long-pulsed 1064-nm neodymium:yttrium-aluminum-garnet (LP 1064-nm Nd:YAG) in conjunction with the 532-nm potassium titanyl phosphate (532-nm KTP) laser wavelengths for treatment of capillary venous and venous malformations.<br />Methods: In this retrospective single-center study, we queried patient records who underwent treatment with the 532-nm KTP and LP 1064-nm Nd:YAG laser wavelengths. A blinded panel of 3 physicians evaluated improvement in lesion color, elevation, texture, and overall architecture on a four-point scale: 0% to 25%; 26% to 50%, 51% to 75%, and 76% to 100%.<br />Results: Our cohort consisted of 23 cases. Sixteen cases had sufficient information for clinical assessment. Treatment number and parameters varied depending on lesion, skin type, and end point. Clinical assessment of treatment effectiveness revealed average scores of 51% to 75% improvement for color, elevation, texture, and overall architecture.<br />Conclusion: This study illustrates that 2 wavelengths, 532-nm KTP to target superficial components and LP 1064-nm Nd:YAG for deeper components, can safely and effectively treat both capillary venous and venous malformations.
