Choosing Phyathai 2 International Hospital for Spider Veins (Sclerotherapy) gives patients access to experienced vein specialists, modern vascular assessment tools, and personalized post-treatment care. Established in 1987, the JCI accredited hospital in Bangkok, Thailand has 550 beds and provides specialized vein treatment services.

Spider Veins (Sclerotherapy) is generally performed as an outpatient procedure and does not usually require major surgery. The treatment area is cleaned before very small needles are used to inject the sclerosant into visible veins. The treated vessels may initially appear darker, swollen, or bruised before gradually fading. Patients are typically encouraged to walk soon after treatment, while strenuous activities may be limited temporarily according to the specialist's advice. Follow-up treatment may be required if additional veins remain visible.
