Good response to pulsed dye laser in patients with capillary malformation-arteriovenous malformation syndrome (CM-AVM).

ABSTRACT

Capillary malformation-arteriovenous malformation syndrome (CM-AVM) is an autosomal dominant disorder caused by heterozygous mutations in RASA1 and EPHB4. Capillary stains in CM-AVM are compatible with Schöbinger's phase I AVMs. Vascular laser has been classically contraindicated for the treatment of AVMs, as there is a fear of accelerating their progression. In this study, we have treated capillary stains in five CM-AVM patients with pulsed dye laser, with improvement and without worsening or recurrence of the lesions after 1 year of clinical and ultrasound follow-up.
