Ultrasound Guided Foam Sclerotherapy
Foam sclerotherapy is another modality to treat veins. It uses the same chemical as injection sclerotherapy but is made into a foam consisting of micro bubbles. The bubbles allow the sclerosant to sit on the surface of the bubbles and come in direct contact with the vein wall. Foam also travels well in veins and can be seen on ultrasound.
It is utilized for larger veins.
It has been previously shown to be inferior to surgical techniques in comparison but can be used as an adjunct for endovenous procedures, where catheter ablations are not technically possible and around ulcerations.
Excellent results can, however, be achieved if patients are followed up as sometimes additional injections are required. We have a set protocol for this to ensure optimal outcomes using foam.
Foam travels well around ulcerations and can be tracked and followed up with ultrasound to aid in healing and reduce recurrence.
Foam can be used in varicose branches that are visible but not large. This may reduce the need for small incisions to remove veins. However, it needs to be weighed up against the chance of the vein re-opening or a lump being felt (thrombosed vein).
