Prior to treatment, your doctor will conduct a complete physical exam to make sure that sclerotherapy or laser treatment is an appropriate response to your condition. Your doctor will be on the lookout for more serious ‘deep vein’ problems, which can often be detected by swelling, sores, or skin changes at the ankle. You may also undergo an ultrasound test to detect any back flow of blood within the venous system. If problems are found with larger veins, they must be treated first by a vascular surgeon, or the spider vein treatment will be probably be unsuccessful.
If you are scheduled for spider vein treatment:
- Avoid alcohol a few days prior to treatment, as alcohol consumption decreases your platelets count, which can lead to excessive bruising.
- Follow your doctor's instructions on what to eat and drink before the procedure.
- Shower or bathe the night before the procedure.
- Wear loose-fitting garments if the treatment is being done on your legs.
