Venous malformations (VMs) are compressible, blue-purple tumors that are present at birth, and are treated with either surgery or sclerotherapy, or a combination of both. Patients often experience recurrent hemorrhage, swelling, pain, or difficulty in daily life. Treatment of massive VMs can, therefore, be challenging. We applied intralesional laser photocoagulation (ILP) to a 19-year-old female patient with a huge VM who had shown resistance to sclerotherapy. It spanned from the dorsal area to the lateral chest. ILP is delivered directly into thick, deep lesions through a bare fiber delivery system. The effect on deep components is optimized without directly contacting the cutaneous or mucosal surfaces to minimize epithelial damage. We applied ILP to the lesion at 30 W in continuous mode (10 seconds) under ultrasound monitoring using an Nd:YAG laser of 1064-nm wavelength. In total, there have been 4 sessions of the same treatment; the lesion was treated with a combined 120 kJ of energy. Satisfactory regression of the huge VM was achieved by this ILP treatment. No significant complications (major bleeding, severe pain, post-perforation skin ulcer, and scar contraction) occurred during the treatment. ILP has been indicated for only sclerotherapy-resistant cases until now, but we suggest that it is a potentially safe and minimally-invasive resolution of VM without scarring or loss of normal shape, sensory feel, or function. ILP appears to be a safe and minimally-invasive resolution of VM. We propose that this technique could become a first-choice treatment modality for VM.
