Percutaneous sclerotherapy for arteriovenous malformations of the face in the outpatient clinic.

Sclerotherapy for arteriovenous malformations has to be performed under general anaesthesia because of the pain during injection and the need of careful monitoring. Two cases with arteriovenous malformations of the face regions are presented in whom percutaneous sclerotherapy was performed under local anaesthesia in the outpatient clinic. The sessions were uneventful and there was a visible decrease in the overall size and an improvement in skin colour of the lesion could be seen. Sclerotherapy can be used in the outpatient clinic to treat arteriovenous malformations that have a slow flow or a venous outflow that can be compressed to artificially slow the flow during injection.
