Sclerotherapy treats varicose and spider veins by directly injecting a chemical solution into the affected veins. This solution causes the vein walls to swell, stick together, and eventually seal shut, blocking blood flow. As a result, the treated vein begins to fade gradually over the following weeks, leading to clearer, smoother skin.
Providers typically perform sclerotherapy in a medical office, and the procedure usually takes about 30 to 45 minutes. Depending on the size and number of veins, patients may need multiple treatment sessions to achieve optimal results.
Before the procedure, the provider conducts a thorough physical examination and reviews the patient’s medical history. In some cases, they may also order vein imaging to assist with treatment planning and to track progress over time.
To prepare for treatment, patients should avoid sun exposure both before and after the procedure, as UV rays can increase the risk of blistering or scarring in the treated areas.
Additionally, the provider may recommend taking aspirin or other blood thinners in the days leading up to the appointment to help reduce post-treatment bruising.
