Which types of lasers are typically used for vascular lesions?

Pulsed dye lasers and Nd:YAG lasers are commonly used for treating vascular lesions due to their specific wavelengths and pulse characteristics which target blood vessels effectively.

Pulsed dye lasers emit a yellow light at a wavelength that is readily absorbed by hemoglobin in the blood. This absorption allows for effective treatment of vascular lesions, such as port wine stains and other vascular malformations. By selectively targeting the vessels without damaging surrounding tissues, these lasers provide a focused approach to treatment, minimizing adverse effects.

Nd:YAG lasers operate at a longer wavelength, penetrating deeper into the skin. They are particularly effective for larger vascular lesions and for areas where deeper tissue penetration is required. The versatility of the Nd:YAG laser allows it to treat a range of vascular issues, including varicose veins and deeper vascular tumors.

Other laser types mentioned in the incorrect options, like CO2 and excimer lasers, are more suited for different skin conditions, such as resurfacing and tattoo removal, rather than specifically targeting vascular lesions. Similarly, diode and ruby lasers do not have the optimal wavelength absorption for vascular lesions as compared to pulsed dye and Nd:YAG lasers. Helium-Neon and argon lasers are often used in applications other than on vascular lesions, further emphasizing
