What are the complications of endovenous thermal ablation of varicose veins?
As with any medical intervention, potential risks and complications exist with the endovenous thermal treatment.
Severe bruising and pain may be experienced at the operated site. This is more common in patients on long-term blood thinners. It usually resolves in a few weeks.
The puncture site may have severe pain and an oozing of fluid from it, suggesting inflammation of the vein (thrombophlebitis). If pus oozes, it suggests a more serious infection and it is recommended to visit your surgeon immediately.
The skin and nerves near the vein can be burnt if the energy settings are high, or if the local (tumescent) anesthesia is not properly administered.
A clot may develop in the deep system of veins (deep vein thrombosis), though this is uncommon if the protocols are properly followed. It is associated with a hard swollen limb and has the risk of the clot dislodging and flowing to the heart and subsequently lungs (pulmonary embolism). This requires prompt diagnosis and management for a good recovery and outcome.
The procedure is now done safely all over the world, usually as an outpatient setting or day care with minimal complications. The techniques are now refined to minimize any problems.
