Comprehensive treatment and rehabilitation of a patient with maxillary arteriovenous malformation

Multiple Arterial Vascular Anomalies in the Periorbital, Paranasal, and Intracranial Spaces Treated With Systemic Bevacizumab

ABSTRACT

Arteriovenous malformations of the orbit are rare congenital hamartomas defined by a direct connection between the arterial and venous systems without an intervening capillary bed. Treatment can be challenging, as these lesions are anatomically complex, often involve multiple locations, and have a tendency to recur. A multidisciplinary approach is typically required, involving endovascular and surgical teams. The authors present a case of a 33-year-old man with a complex, recurrent orbital arteriovenous malformations in the context of wider head and neck vascular anomaly syndrome involving the paranasal sinuses, deep facial tissues, and intracranial spaces. The complex and evolving clinical manifestations of this disease are presented with emphasis on the interdependence of the anomalies and biologic management strategies.

Comprehensive Treatment of Upper Lip Arteriovenous Malformation

Arteriovenous malformations are uncommon congenital disorders in vascular development. They frequently involve craniofacial structures and result in a morphogenic abnormality with ominous arteriovenous shunting. We present a huge AVM of the upper lip in an 18-year-old patient who was successfully treated by the combination method of presurgical endovascular embolization and complete resection of the lesion. Subsequent surgical defect in upper lip, which involved more than two-third of the lip length, was reconstructed via Webster's modification of cheek advancement flap.
