BACKGROUND

The longevity of foam made using sodium tetradecyl sulphate and gas (air or a CO2:O2 mixture) is increased significantly if silicone-free syringes are used over the normal syringes containing silicone oil lubrication. However, the plungers in silicone-free syringes start sticking after several passages when making foam for sclerotherapy, preventing the smooth injection of the resulting foam. We describe a three syringe technique which allows foam to be made using the Tessari Tourbillon ‘three-way stopcock’ principle between two syringes, but with the foam ending up in a third syringe which has not undergone multiple passages of the plunger. This allows a smoother injection of the resultant foam, which is particularly useful when injecting small diameter veins under ultrasound control.

THE STUDY

This is a new technique, invented at The Whiteley Clinic by Mark Whiteley and Salil Patel to make sure that the foam made and given to patients is optimised to give the best results.

Previous research from The Whiteley Clinic has shown that foam for sclerotherapy can be made better if silicone free syringes are used. Also, for safety, air should not be used. Nonsilicone syringes stick after making foam – so a 3 syringe technique was devised to ensure the injecting syringe is undamaged at the time of injection.

CONCLUSIONS

The Whiteley-Patel 3 syringe technique is a modification of the Tessari 2 syringe technique that allows foam to be produced in the research proven optimal manner, and then injected without the syringe sticking.

INTERESTING POINT

The pressures generated in making the foam mean a special silicone free syringe with a Luer Lock end is needed – several ties were ruined in discovering the optimal configuration.
