Foam sclerotherapy treatment differs from traditional sclerotherapy in making the sclerotherapy solution into foam before injecting it into the vein. The foam is made by fast stirring the solution and mixing it with air. Foam sclerotherapy is used to treat larger underlying veins that can’t be treated with traditional sclerotherapy.
The treatment with foam can also be done under ultrasound control.
Before the treatment, the doctor marks the surface vein that will be treated on the patient’s leg for example, with ultrasound scanning. Then the patient is given local anesthesia in the lower thigh or the middle of the calf. After that, the doctor places a needle in the patient’s vein with the help of ultrasound scanning. Then two or three small needles are placed into the varicose vein and a foam solution is injected slowly into each needle. While the doctor is injecting the foam, the patient bends his/her ankle up and down to boost the blood flow in his/her deeper veins.
During the treatment, the patient may feel mild stinging while the foam is being injected but it is not very uncomfortable. The doctor monitors the pass of the foam through the patient’s vein with ultrasound and repeats the injection of the foam 2 or 3 times.
After the doctor has injected all the foam, here moves the needles and applies compression pads to the patient’s leg and wraps it with a bandage. The patient then receives an elastic compression stocking to keep the treated vein compressed. The compression stocking should be tight but not too much.
The patient is then free to go, but it is a good idea to have someone drive him/her home.
During the recovery period, the patient should walk a lot and do all his/her normal daily activities.
The patient may need more treatment sessions to achieve the best results. The doctor determines the number of sessions during the consultation. Each session should be a few weeks spaced apart. Usually, it is necessary to have 2 to 3 sessions to improve the appearance of varicose veins with foam sclerotherapy.
