Long-pulsed 1064 nm Nd:YAG laser can damage vessels with higher diameters and penetrate to a deeper level than other laser therapies. We aim to analyze outcomes of the treatment of leg veins with long-pulsed 1064 nm Nd:YAG laser regarding intervention protocol, technical success, clinical success, and side effects. A research of the published literature was conducted, using PubMed and Embase databases, in April 2022. The key words used were telangiectasia, reticular veins, neodymium YAG laser, clearance, satisfaction, and treatment. PRISMA guidelines were followed. We included twenty-six articles, twenty-three prospective and three retrospective studies, with a total of 1991 patients. The articles were organized in different sections according to the control group. The four outcomes were analyzed in each section. These studies showed that the long-pulsed 1064 nm Nd:YAG laser is a safe and very good option for the treatment of leg veins measuring up to 3 mm in diameter. Studies comparing long-pulsed 1064 nm Nd:YAG laser therapy and sclerotherapy showed similar clearance rates with no significant differences. However, sclerotherapy seemed to be less painful and to have faster clinical improvements. In two articles, Nd:YAG laser had better outcomes in the treatment of smaller vessels with less than 1 mm in diameter, than sclerotherapy alone. Treatment with polidocanol microfoam and Nd:YAG laser had better clearance rates than Nd:YAG laser alone in three studies. In the comparison of 1064 nm Nd:YAG laser therapy with other lasers and light sources, the studies had contradictory results. Long-pulsed 1064 nm Nd:YAG laser is a valid therapeutic option for leg telangiectasia and reticular veins with great aesthetic outcomes and minor side effects. Nd:YAG laser therapy could be combined with sclerotherapy or other laser therapies or IPL in order to achieve better results. Serious side effects are rare, but the procedure is almost always accompanied by moderate tolerable pain.
