Is it safe to get non-foam sclerotherapy if I have a PFO?

There are many patients who have PFO's who get foam sclerotherapy without incident. Most PFO's remain undiagnosed and asymptomatic.It is not just having a PFO, but a right to left shunt that is key. This is done with a bubble test which I assume you have already had.If there is no shunt, the likelihood of air going through is unlikely.I would, however, stick with traditional sclerotherapy to avoid potential problems or limit the amount of foam sclerotherapy to less than 5 cc at a time and keep the legs elevated above the level of the heart.Discuss with your treating doctor.H KaramanoukianCardiovascular surgeon and vein specialist

Liquid sclerotherapy is safe to use with a PFO.  However. I would recommend that you have a cardiac evaluation before preceding with any further treatment. I had a patient about 2 years ago that developed severe headaches after foam sclerotherapy and further evaluation revealed a similar experience following her colonoscopy.  Cardiac eval revealed a large PFO which was corrected. Why take any risks?  Have a cardiac evaluation.

Thank you for your question.  I am so sorry to hear about the complication you suffered, and I hope you make a full recovery.  I personally perform quite a bit of injection sclerotherapy in my practice.  The issue of having an air embolism following sclerotherapy in a patient with a PFO was never an issue prior to the use of foam.  If you have regular liquid sclerotherapy without any air mixed with the sclerosant your will have a low air embolism risk. Hope this helps!
