Arteriovenous Malformation of Upper Lip- A Case Report with Literature Review

10.30699/jambs.30.142.458 Arteriovenous malformations (AVMs) of the head and neck are rare vascular benign anomalies but may become lethal when persistent and progressive. It occurs when a fetal capillary bed fails to fully involute, allowing direct connection between arteries and veins. They can also happen as a result of trauma or a hormonal changes. Clinically along with swelling, they are associated with signs of warmth, palpable thrill or bruit. Management of the lesion is challenging and follows a multimodal laser therapy approach followed by embolization and surgical resection. Complete excision is required as incomplete excision leads to recurrence. A detailed clinical background combined with imaging generally clearly delineates the lesion and allows for a careful therapeutic option. A case report of a post-traumatic/acquired AVM on the upper lip is presented in this report which was diagnosed on contrast tomography Angiogram and MRI in a 7year old female and treated with intralesional corticosteroids followed by surgical excision.
