Abstract

We have recently developed a novel, cavitation-based, highly selective anti-vascular technique, termed photo-mediated ultrasound therapy (PUT). In this study, the effectiveness and safety of PUT on cutaneous vascular malformation was examined through in vivo experiments in a clinically relevant chicken wattle model. The typical results showed perfusion stop of microvessel on OCT angiography and fade of the wattle color on skin imager after treatment. The safety is checked by H&E histology and immunohistochemistry evaluations include: CD31, Caspase-3, and Masson’s Trichrome (MTC) stains. The findings demonstrate that PUT can efficiently and safely remove hypervascular dermal capillaries by using laser fluence at a level which is orders of magnitude smaller than that used in conventional laser treatment of vascular lesions, thus offering a safer alternative technique for clinical management of cutaneous vascular malformations.
