Eyelid arteriovenous malformation treated with pre-surgical embolization: A case report.

Background Arteriovenous malformations are potentially serious vascular anomalies that are rarely encountered in the eyelid and require a multidisciplinary approach. Objectives We would like to describe the technical and clinical aspects related to the treatment of palpebral arteriovenous malformation with selective embolization, followed by surgical resection. Methods A 40-year-old patient presented with an isolated high-flow palpebral arteriovenous malformation. Transarterial embolization, using a liquid embolic agent (PHIL™), was performed in this patient. Results Angiographic and clinical follow-up revealed good results with clinical regression of the mass. Conclusion Although endovascular treatment of palpebral arteriovenous malformations is technically challenging, good functional and cosmetic result was achieved. Arteriovenous malformation embolization using PHIL™ seems to be very effective and makes subsequent surgical procedure safe and feasible. Level IV Evidence obtained from multiple time series with or without the intervention, such as case studies. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.
