Comprehensive Management of a Giant Venous Malformation of the Lip: Vascular Embolization Followed by Surgical Resection and Reconstruction

Venous malformations often manifest in early childhood and do not spontaneously resolve. Most vein malformations of the lips are typically treated at a young age, with giant arteriovenous malformations being particularly rare. Herein, we introduce the case of a 47-year-old man who presented to our department complaining of a progressive mass on his lower lip. Clinical examination revealed a mass measuring 10 cm x 8 cm x 4 cm in size, characterized by a soft texture and smooth edges. Despite a series of sclerotherapy interventions, the lesion remained unresponsive. Consequently, we performed a preoperative embolization of the malformed vessel using digital angiography, followed by extensive resection of the lesion and repair of the defect using an adjacent flap. The postoperative period was uneventful, and no local recurrence was observed during a 4-year follow-up period. Therefore, we recommend preoperative angioembolization as a valuable approach for addressing large lower lip deformities to enable extensive surgical resection and robust therapeutic outcomes.
