Arteriovenous Malformation of the Upper Eyelid: A Case Report

Arteriovenous malformations (AVMs) are rare lesions formed by direct connection of arteries and veins bypassing capillary beds. AVM locations can vary; however, extracranial AVMs remain the least common. The vast majority of these malformations are congenital and can be triggered by hormonal changes. A 49-year-old woman presented with a progressive right-sided upper eyelid swelling over the past 12 years. The patient had mechanical ptosis and mild impairment of the right visual field. The swelling was compressible with a thrill, and bruits were heard. The patient was diagnosed with AVM using cerebral angiography. Preoperative endovascular embolization was not possible; however, surgical excision was successfully clone with no complications. AVMs and fistulas are high-flow vascular lesions that usually occur during childhood and progress with time. Only a few cases of face And eyelid AVMs have been reported in the literature. Diagnosis of these anomalies is mostly made based on clinical presentation and radiographic imaging such is angiography. Treatment options remain controversial, and management should he individualized for each patient. Endovascular embolization followed by surgical excision is advisable in many cases. Due to its rare entity, information regarding the best management options for AVMs is limited. Reducing the risk of bleeding and achieving total resection is the goal of treatment. Long-term follow-up is required in these patients because recurrent cases of AVMs have been reported.
