Successful treatment of large venous malformation with dual wavelength 595 and 1064 nm system.

Venous malformations (VMs) are congenital soft, compressible, non-pulsatile blue-purple masses. VMs present a therapeutic challenge. They can be treated with surgery or sclerotherapy as well as with several lasers. We report the successful treatment of two patients with large VMs with combined sequential application of 595 nm pulsed dye laser and 1064 nm Nd:YAG wavelengths. At the end of the treatment course, total volume reduction was observed in both. All sessions were well tolerated without anesthesia. In our patients, using this sequential laser device achieved an almost complete clearance of the VM with no scarring.
