When discussing laser therapy for a capillary vascular malformation, which statement is most accurate about treatment?

• A. Multiple treatments over many months may be required
• B. Transient edema can be expected to last several months
• C. Gray-black discoloration will fade in 3 to 4 days
• D. The birthmark will gradually fade over 1 to 2 years

Answer: (A)

Laser therapy for capillary vascular malformations typically works gradually, requiring several treatment sessions over many months to achieve meaningful improvement. Each session targets a portion of the abnormal vessels, and healing with vessel remodeling takes time, so the overall course extends beyond a single treatment. Post-treatment swelling is usually mild and temporary, lasting days to a couple of weeks, not months. Pigment changes can occur and may take weeks to months to resolve, rather than fading within a few days. While some gradual fading can happen with ongoing sessions, the most accurate description of expected treatment course is that multiple sessions over months are often needed.
