What is Chemoablation?
When it has been determined that thermal ablation (heat) will not work for venous closure for a patient, endogenous chemoablation is a consideration.
Endovenous chemoablation sometimes referred to as ECA, is performed on an outpatient basis. No sedation is required. A chemical solution is injected into the damaged veins to produce endothelial destruction which is followed by the formation of fibrotic cords and eventually reabsorbed into the surrounding tissues. The osmotic agent Hypertonic Saline has been used for decades to treat smaller varicose veins and spider veins. They are now being used to treat larger veins as well.
ECA is often the only option for patients who have formerly undergone vein stripping and still have areas where the vein is too gnarled and twisted to use heat ablation. ECA is best utilized for veins that are inaccessible by laser or radiofrequency ablation.
The beauty of using chemoablation is that foam sclerosants allow for a visual working image allowing the doctor to guide its course easily with ultrasound guidance.
What kind of results can you expect?
Veins begin to fade within a few weeks although it may take a few months to see final results. Chemoablation can also improve related symptoms like aching, burning, cramping, swelling and more.
Recommendations post chemoablation
It is beneficial to exercise and maintain a healthy weight. Movement during the day rather than long periods of sitting or standing still can help boost vein health as well.
