Objectives: This session will present practical strategies for selecting between pulsed dye lasers and long-pulsed KTP and Nd:YAG lasers—or employing them in combination—based on specific clinical presentations. The aim is to optimize treatment efficacy and safety in managing vascular conditions. Introduction: Pulsed dye lasers (PDL), such as the Vbeam, are considered the gold standard for vascular lesions. However, long-pulsed KTP and Nd:YAG lasers (e.g., DermaV) have gained traction due to their versatility across a broader range of vascular indications. Materials / method: In our high-volume dermatology clinic, we treat approximately 40 vascular cases per day, providing substantial clinical experience with both laser modalities. We conducted an analysis of patient charts and clinical photographs to compare efficacy and safety profiles across various vascular presentations. Results: Both PDL and long-pulsed KTP/Nd:YAG lasers demonstrated good efficacy in treating facial redness and telangiectasia with multiple sessions, though individual responses varied. Long-pulsed Nd:YAG lasers showed superior results in treating deeper vascular lesions, such as venous lakes, telangiectasia on the extremities, and recalcitrant warts. Conversely, PDL offered a more favorable safety profile, particularly in cases where vascular lesions overlapped with pigmentary disorders such as melasma. Conclusion: Pulsed dye and long-pulsed KTP/Nd:YAG lasers each offer distinct advantages in treating vascular conditions. Access to both technologies allows for a tailored, patient-specific approach—either as standalone or combination therapies—leading to faster, safer, and more effective treatment outcomes.
