Intraoral excision of arteriovenous malformation of lower lip.
Vascular malformations can be categorized into low-flow lesions and high-flow lesions according to blood flow volume. Arterial lesions such as arteriovenous malformations (AVMs) are generally high-flow lesions. Arteriovenous malformations are high-flow vascular anomalies consisting of a nidus or a network of abnormal vascular channels between feeding arteries and draining veins. Arteriovenous malformations become destructive progressively by compression or erosion of surrounding tissue by itself. Angiography is the most important diagnostic technique for determination of location and flow characteristics of vascular lesions. Embolization is used preoperatively to decrease the size of AVM and reduce the extent of surgical excision. The modern treatment of AVM requires multidisciplinary study between the surgeon and vascular radiologist. We reported an early diagnosed AVM at the lower lip, and it was resected totally intraorally without any complication and morbidity.
