What are the side effects of vein treatment ?

Procedures & Surgical Interventions to remove varicose veins:

Medical procedures are done either to remove varicose veins or to close them. Removing or closing varicose veins usually doesn’t cause problems with blood flow because the blood starts moving through other veins.

You may be treated with one or more of the procedures listed below.Your vein specialist should review potential complications of either procedure at the consultation, which can include bruising, swelling, skin discoloration, vessel perforation, thrombosis, pulmonary embolism, phlebitis, hematoma, infection, paresthesia (numbness or tingling), skin burn and slight pain.


Sclerotherapy (SKLER-o-ther-a-pe) uses a liquid chemical to close off a varicose vein. The chemical is injected into the vein to cause irritation and scarring inside the vein. The irritation and scarring cause the vein to close off, and it fades away.

This procedure often is used to treat smaller varicose veins and spider veins. It can be done in your doctor’s office, while you stand. However, It may not even be necessary to treat the varicose/spider veins, once the underlying bad veins get treated properly.

Laser Ablation:

Laser ablation (ab-LA-shun) This procedure applies laser into a vein through a catheter. Usually bruising is worse with Laser Ablation in compare to Radio Frequency Ablation. The most important complication risk is deep venous thrombosis (DVT). However, since this is a known phenomenon there is a number of preventive steps that if were followed the risks would significantly be minimized.

Endovenous Ablation Therapy:

Endovenous ablation (ab-LA- shun) therapy uses radio waves to create heat to close off a bad vein. Your doctor makes a tiny cut in your skin. He or she then inserts a small tube called a catheter into the vein. A device at the tip of the tube heats up the inside of the vein and closes it off. You will be awake during this procedure, but your doctor will numb the area around the vein. You usually can go home the same day as the  procedure. Although, radiofrequency ablation of the veins is considered to be a very safe procedure, this  like any other procedure may have some potential risks. The most important side effect is deep venous thrombosis (DVT) like in Laser Ablation. Other less serious but potential risks include cellulites/infection, skin burn, some blood loss, bruising, mild pain and numbness/tingling in the treated area.  In our experience, the majority of our patients have enjoyed a wonderful benefit by undergoing this minimally invasive procedure.

Clarivein Occlusion:

MOCA (Mechanical Occlusion Chemically Assisted) uses mechanical agitation of the lining of the vein together with a sclerosing chemical to glue the vessel closed. It is an effective and safe technique with no pain. There is minimal discomfort and negligible bruising with no risk of thermal (heat) damage as there may be with techniques such as laser or radiofrequency ablation. There is no risk of nerve or skin damage, no multiple needle stick injuries, no tumescent or anaesthetic, no internal leg pressure but rapid return to normal activities. Like all other procedures there is always some side effects. Deep venous thrombosis (DVT) is the most well known, but there may be minimal bruising, some blood loss and cellulites/infection.

Vein Stripping and Ligation:

Vein stripping and ligation(li-GA-shun) typically is done only for severe cases of varicose veins. This is a surgery and involves tying shut and removing the veins through small cuts in your skin. You will be given medicine to temporarily put you to sleep so you do not feel any pain during the procedure. Vein stripping and ligation usually is done as an outpatient procedure. The recovery time from the procedure is about 1 to 4 weeks. The side effects are most severe with vein stripping and ligation. Although rare, this surgery can cause severe pain, infection, blood clots, and scarring. Vein stripping is not used very often anymore, since there are minimal invasive procedures that have replaced the old fashioned surgery.

Temporary side effects:

Some side effects that may occur at the site of the injection include:


  • Bruising
  • Darkened skin in the form of lines or spots
  • Vessel perforation
  • Thrombosis
  • Pulmonary embolism
  • Phlebitis
  • Hematoma
  • Infection
  • Paresthesia (numbness or tingling)
  • Skin burn


Here at Alpha Vein Clinic majority of our patients have enjoyed a wonderful benefit by undergoing the minimally invasive procedures.

Allergic reaction: It is possible that you may have an allergic reaction to the solution used for treatment, but this is uncommon.

Seeking professional treatment is the only way to get rid of varicose veins for good. Each case is different, and if you’re wondering about the best way to go about varicose vein treatment, it’s a great idea to talk to a vein expert. In the past, the only way to get rid of varicose veins was through invasive surgery. Today, minimally-invasive procedures like Radiofrequency Ablation and Clarivein Ablation allow for accurate treatment with less risk of damage to surrounding tissues, and faster recovery time.
