Abstract

Arterial venous malformations (AVMs) are rare conditions that are difficult to manage. Therapeutic options include selective embolization with or without surgical excision. Recurrence, however, is high despite correction of the primary abnormality. Cosmetic concern is among the indications for treatment, particularly if the AVM occurs on the face or scalp. Historically, AVM excision and the residual defect correction have been performed separately. We present the first case reported of a successful embolization and interval excision with immediate reconstruction using a dermal fat graft, as a novel approach to correct soft tissue defect following the resection of an AVM. A 35-year-old man presented with a 20-year history of a nonpulsating mass posterior to the hairline in the right frontoparietal region, measuring 4.0 cm on its longest axis. Embolization of the AVM was achieved by injecting N-butyl cyanoacrylic acid and ethiodol. One month after embolization, surgical excision of the mass was performed. The resulting disfiguring contour defect was immediately corrected using a dermal fat graft harvested from the groin. At 4 months' follow-up, the graft was viable with no evidence of resorption or epidermal cyst formation. In addition, there was no recurrence of the AVM and no complications at the donor site. This case demonstrates the utility of a dermal fat grafts in correcting the impending defect in 1 stage avoiding a second-stage procedure and significant period of cosmetic disfigurement. This method should be considered as a treatment option for patients requiring moderately sized AVM excisions in cosmetically sensitive areas.
