Endovascular Laser Treatment (EVLT): Caring for your child at home after the procedure

Your child has had EVLT. This brochure explains how to care for your child at home after the procedure, and when to call for help.

What to expect after EVLT

Your child may experience the following symptoms:

  • Bruising along the treated vein.
  • Swelling in the area where the vein was treated.
  • Slight tenderness in the treated area.
  • A "pulling" sensation in the leg where EVLT was done. This may occur a couple of days after the procedure. If your child is in pain, give them ibuprofen​ (Motrin® or Advil®) for 48 hours.

When to see a doctor 

Phone your specialist or Image Guided Therapy (IGT), or go to the nearest Emergency Department right away if your child has any of the following:

  • fever greater then 38°C (100.4°F)
  • severe pain in treatment area
  • generalized swelling of leg
  • skin blisters

Pressure Garment

Your child may be prescribed a high pressure garment to wear. This garment must be worn 24 hours a day for two days. After 48 hours, the garment must be worn during the day for six weeks.

Pain relief

Your child may feel local pain or discomfort after the procedure. This may last one or two days. If needed, give your child acetaminophen (Tylenol®) for pain. Do not give your child any medicines that will thin the blood, such as ASA (Aspirin®) or ibuprofen (Advil® or Motrin®), without checking with a nurse or your child's doctor first.


If your child is feeling well enough after the anaesthetic, they can return to eating what they normally eat. It is also important to encourage your child to drink plenty of fluids for 48 hours after the procedure.


Your child may have a bath or shower two days after the procedure. Use unscented soap to clean the treated area.


Your child can resume gentle activities 24 hours after the procedure. These include walking and going to school. Your child should avoid any major physical activity for six weeks, such as:

  • contact sports
  • gymnastics
  • diving/swimming
  • bicycle riding
  • rollerblading
  • hockey
  • soccer
  • skiing
  • horseback riding
