Vascular Lesion Laser Treatment in Toronto and Richmond Hill Clinics
LASER TREATMENT FOR VASCULAR LESION
Vascular lesions include skin conditions that arise from or influence blood or lymphatic vessels, such as tumours, malformations, and inflammatory diseases. A vascular anomaly is any range of lesions from birthmarks to large tumours. Lasers have become integral to managing hemangiomas and vascular malformations of many types. Patient outcomes have improved with discoveries in laser technology and technique.
Cutaneous vascular lesions include skin diseases that arise from or influence blood or lymphatic vessels, such as tumours, malformations, and inflammatory diseases. While some vascular lesions are easily detected clinically using methods such as skin surface microscopy, others can be difficult to differentiate because many have similar dermoscopic features.
There are other ways to treat this issue, but the most popular method is laser treatment for cutaneous vascular lesions. This treatment method has progressed significantly over the past 30 years.
One of the most common applications of lasers in dermatology is the treatment of the vascular lesion. Lasers have generally become the treatment for vascular birthmarks such as hemangiomas, port-wine stains, and rosacea telangiectasia. The number of congenital and acquired vascular lesions that can be efficiently treated with lasers is growing.
Multiple cutaneous vascular lesions, including telangiectasias, port wine stains (PWS; sometimes known as port wine birthmarks), and infantile hemangiomas, are treated with lasers and intense pulsed light (IPL). During treatment, light energy absorption by intravascular oxyhemoglobin causes heating and coagulation of lesioned blood vessels. The type of light source employed, the clinical characteristics of the target lesion, and patient-specific factors all influence how vascular lesions respond to therapy (e.g., skin colour, patient age).
Although laser and IPL therapy can provide clinical benefits, the procedure is not without risks. If clinicians are not careful, injuries can result, involving areas such as the skin or eyes. Using suitable equipment settings, skin cooling systems, and other safety measures reduces the occurrence of treatment-related injuries and adverse effects.
Laser irradiation can selectively kill specific targets (chromophores) within the skin by employing an appropriate wavelength, pulse duration, and energy setting. To prevent damage to adjacent structures, the pulse duration must be less than or equal to the chromophore’s targeted thermal relaxation time, i.e. the time required for the target to cool by half its peak temperature following laser irradiation. Because the energy deposited in the tissue is restricted to specific locations, considerable thermal diffusion to the surrounding skin is avoided.
Furthermore, because the wavelengths correspond to absorption peaks for distinct skin chromophores, laser energy absorption can be concentrated without causing damage to surrounding structures. Because intravascular oxyhemoglobin is the targeted chromophore for vascular lesions, thermal damage is limited mainly to cutaneous blood vessels. The major oxyhemoglobin absorption peaks are at 418, 542, and 577 nm, with the latter being optimum.
Who's at risk?
A typical candidate has diffuse redness (many fine blood vessels appearing), specific troublesome linear blood vessels, or both. The face, particularly the nose, is the most typically treated area. The treatment may take up to a month to take full effect, but the result is permanent. On the other hand, people who have an excess of blood vessels may develop new vessels that will necessitate treatment in the future.
Vascular Lesion Treatment Procedure
There are various versions of a “normal session” in laser vascular lesion treatment, and what happens throughout the session varies on the technology utilized. If the treatment is uncomfortable, numbing cream is sometimes applied 30–90 minutes before the procedure. The patient will lie on an exam bed, and the area will be cleansed to remove any makeup before the treatment. Everyone in the room must wear eye protection once the treatment area has been identified and confirmed by the patient. Metal-lined adhesive pads, goggles, or eye shields, either over or under the eyelid, are some of the eye protection options available to patients.
The doctor will use the following program to the equipment with the necessary settings and select a handpiece. The handpiece is placed on the skin, and the pulse of laser energy is fired using either a trigger or a foot pedal, targeting a 1–3 cm area of skin. The feeling during the treatment is fleeting, and each laser pulse is commonly characterized as a warm pin-prick. Treatment timeframes vary depending on the size of the region to be treated and the equipment employed, but they typically last 15–30 minutes.
How to prepare for a vascular lesion laser session:
- Avoid getting tanned — Stay out of the sun during the day, use sunscreen with a high SPF, and wear UV-protective clothing (e.g., a hat and tightly woven clothing).
- If necessary, apply numbing cream 30–90 minutes before the surgery.
- Avoid drugs and supplements that increase the likelihood of bruising (only if quitting any of the following medications has been discussed with your doctor):
- Vitamin E
- Fish oil supplements
- Prescription blood-thinning medications
What outcome should patients expect?
Lesions may dissolve entirely after 1-2 treatments or require a series of treatments, depending on the condition. The patient must follow post-operative care requirements, such as limiting sun exposure and applying broad-spectrum sunscreen regularly.
Treatment techniques are frequently based on the patient’s skin type. There is a more significant risk of problems with particular disorders or skin types. It is critical for the patient to do their homework ahead of time to find a practitioner who has the necessary skills and experience to perform the treatment.
