Such a red birthmark is called "wine spot" in medicine, also known as "angel kiss", which is a benign vascular malformation. At present, the commonly used treatment methods are dye laser therapy and photodynamic therapy. Because the curative effect of pulsed dye laser is affected by factors such as blood vessel diameter, some patients may not be significantly improved. However, Heimpofen photodynamic therapy does not have this concern. What about Hamboffin?
Targeted therapy
Generally speaking, the so-called photodynamic therapy is to combine drugs with light technology to treat port wine stains. By intravenous injection of photosensitizer into patients, photochemical reaction will occur under the action of light, which will selectively destroy deformed capillaries and achieve therapeutic effect.
Heimpofen is the only photosensitizer approved for the treatment of port wine stains on the market at present. It can accurately destroy the deformed blood vessel wall, make vascular endothelial cells apoptosis or necrosis, thus disintegrating the whole deformed blood vessel, and there is no fear that pulsed dye laser will cause blood vessel blockage. It is a good choice for patients with large area of port wine nevus (14 years old or above) or who have failed to respond to laser treatment for many times.
Quick onset and low risk of recurrence.
Heimpofen photodynamic therapy takes effect faster than pulsed dye laser, and the effect of one treatment is 5-6 times that of pulsed dye laser treatment, which is effective for large-area port wine stains or port wine stains that are ineffective by laser. Moreover, it is difficult to repair and regenerate blood vessels after photodynamic injury, and the risk of recurrence and scarring is small. Generally, treatment is needed for 2-3 times with an interval of 2-3 months.
Matters needing attention
Because Heimpofen will remain in the body for a period of time after being used as a photosensitizer, in order to avoid the influence of light on other skin of the whole body, it is necessary to avoid direct sunlight and strong light irradiation on the skin for 2 weeks, and the indoor light is unobstructed. When going out, it is necessary to take hard sun protection measures, such as wearing sun protection clothes and umbrellas.
After treatment, itching, pain, erythema, swelling, scabbing, pigmentation and other symptoms may occur, most of which are mild and can recover in a short time without special treatment. If there are blisters and purpura, you can apply cold compress and sunscreen. However, if you have systemic urticaria, shortness of breath, etc. Especially if the skin is exposed to sunlight or strong light, you need to go to the hospital immediately.
conclusion
Heimpofen provides a new treatment direction and a safer and more reliable treatment method for "angel kiss" children. Let more patients get rid of erythema and regain their confidence in life!
