Sclerotherapy has successfully been used to treat varicose and spider veins for many decades. In fact, modern sclerotherapy began in the 1940s. Today, it has clinical success rates of 80 to 90 percent. But it’s normal to be apprehensive before any procedure. To best prepare for your appointment and ease your mind, continue reading to learn what happens when you receive a sclerotherapy injection.

What happens during sclerotherapy injections?

Because it’s a minimally invasive procedure, sclerotherapy has become one of the most popular treatments for spider veins and smaller varicose veins. You won’t need a lengthy hospital stay, as this outpatient procedure can be performed at your vein doctor’s office and typically takes no more than an hour.

Two types of sclerosants are commonly used. One is a saline solution. The other is a foam sclerosant. Despite the technique, the procedure is similar for both. Here’s what to expect before, during, and after the procedure:

Pre-procedure: Your doctor may ask you to refrain from taking certain medications prior to the procedure. Avoid shaving or putting lotion on the affected area. You can eat your regular diet the night before, but drinking a lot of water is always a good idea.

During the procedure: You’ll lie on a table with your knees slightly bent. Because the needle that injects the sclerosant is so thin, you won’t need any anesthesia. You might feel slight stinging or cramping as the needle enters the vein, but it’ll soon pass.

The sclerosant irritates the vein walls, collapsing and sealing them. Your doctor may apply gentle pressure to ensure the solution reaches the entire affected vein. Blood from the treated vein will then divert to nearby healthy veins. Over time, the varicose vein or spider vein will disappear. Depending on how many veins need to be treated, several sessions may be required to treat all problematic veins.

Post-procedure: You can leave the appointment immediately and resume your daily activities with few restrictions. Your doctor may recommend wearing compression stockings to promote healing. While you should avoid strenuous activities for about two weeks, walking for as little as 20 minutes daily can help your healing process.

Complications. Rarely do complications result from sclerotherapy. Any bruising and discomfort should be minor and temporary. An allergic reaction to the sclerosant is also extremely rare.

Of course, if you experience any unusual or lingering symptoms, report them to your vein specialist. Otherwise, you can expect a successful and uneventful recovery from your sclerotherapy injection.
