Sclerotherapy: Overview, Preparation, Procedure, Recovery, Risks, and Aftercare
Overview
Injection of a sclerosing agent into the affected veins causes them to shrink, collapse, and fade from view. Sclerotherapy is a minimally invasive medical procedure used to treat varicose veins and spider veins. Dermatologists or vascular specialists often perform sclerosing therapy to improve cosmetic appearance or alleviate varicose vein symptoms, such as pain, swelling, and discomfort.
Preparation
Patients typically undergo the following preparation steps before undergoing sclerotherapy:
-
During a consultation, patients discuss their symptoms, medical history, and treatment goals with a healthcare provider who specializes in vein disorders. In addition to performing a physical examination during the consultation, the provider may recommend imaging tests, such as ultrasound, to determine the extent and severity of the vein condition.
-
Patients may undergo a comprehensive medical evaluation to determine their candidacy for sclerotherapy or to identify any underlying medical conditions that may increase their risk of complications.
-
Patients receive pre-procedure instructions from their healthcare providers, which may include avoiding certain medications (e.g., blood thinners), abstaining from smoking, and wearing loose-fitting clothing on the day of the procedure.
Procedure
Sclerotherapy typically involves the following steps:
-
A special magnifying light is used to identify the target veins after the skin is cleansed and sanitized.
-
A fine needle is used to inject a sclerosing agent directly into the affected veins. The sclerosing agent irritates the vein walls, causing them to collapse and stick together, ultimately sealing the vein off.
-
Pressure or compression may be applied to the treated area after injection to enhance the distribution and effectiveness of the sclerosing solution.
-
Depending on the severity of the vein condition and the desired outcomes, multiple sclerotherapy sessions may be necessary to achieve optimal results. These sessions are typically spaced several weeks apart to ensure adequate healing.
Recovery
Sclerotherapy patients can expect the following recovery process after undergoing the procedure:
-
Sclerotherapy patients can resume normal activities immediately after the procedure. However, they may be advised to avoid strenuous exercise, prolonged standing, and hot baths for a few days following the procedure.
-
To promote healing, reduce swelling, and support the treated veins, patients may be instructed to wear compression stockings or bandages.
-
Typically, patients are advised to schedule follow-up appointments with their healthcare provider to monitor healing progress, assess treatment outcomes, and address any concerns or complications.
Risks
Despite the fact that sclerotherapy is generally considered safe and well-tolerated, it does carry inherent risks and complications, including:
-
The injection sites may experience mild bruising, redness, or discoloration, but these side effects usually resolve on their own over time.
-
In rare cases, patients may experience an allergic reaction to the sclerosing agent, resulting in symptoms such as hives, itching, or difficulty breathing. If this happens, immediate medical attention is necessary.
-
Sclerotherapy can cause changes in skin pigmentation, resulting in darkening (hyperpigmentation) or lightening (hypopigmentation) of the treated areas.
Aftercare
After sclerotherapy, patients should follow the following aftercare instructions:
-
Sun exposure should be avoided and sunscreen should be used to protect the treated skin from UV radiation, which can exacerbate pigmentation changes and increase complications.
-
Light exercise and regular physical activity can promote circulation, reduce swelling, and improve vein health. However, patients should avoid high-impact activities or heavy lifting for a few days following surgery.
-
Maintain hydration: Staying hydrated can prevent blood clots and promote overall vascular health.
Patients can make informed decisions, prepare for their treatment experience, and achieve optimal outcomes by understanding the overview, preparation, procedure, recovery, risks, and aftercare associated with sclerotherapy.
