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.

“…This growth is the result of vascular recruitment and collateralization with the acquisition of feeding arteries and draining veins, which conduce to increasing blood flow through the lesion. On occasions, rapid expansion can occur following trauma, infection, and hormonal changes including puberty or pregnancy [3][4][5][6][7][8][9][10].…”

“…Las malformaciones vasculares a su vez se pueden clasificar, según sus características en la angiografía, en lesiones de bajo flujo (venosas, capilares y linfáticas) o de alto flujo (malformaciones arteriovenosas (MAV), arteriales y fístulas arterio-venosas) 1,4 . La importancia de las MAVs de alto flujo radica en que el 50% está localizado en la región craneofacial y pueden producir sangrado con riesgo vital sin un diagnóstico y tratamiento adecuado 5,6 .…”

Resección quirúrgica de malformación arteriovenosa de alto flujo en ángulo nasogeniano con embolización preoperatoria: Reporte de un caso

El 50% de las malformaciones arteriovenosas (MAVs) de alto flujo se ubican en la región craneofacial y pueden producir sangrado con riesgo vital sin diagnóstico y tratamiento adecuado. La resonancia magnética (RM) es útil en el diagnóstico diferencial de las lesiones vasculares, siendo el gold standard la angiografía selectiva. Dado que las MAVs de alto flujo no involucionan espontáneamente, el tratamiento usualmente consiste en embolización con posterior resección quirúrgica. Se presenta un paciente de sexo masculino de 20 años que consulta por aumento de volumen nasogeniano derecho, progresivo, violáceo, blando y pulsátil. Se objetiva mediante RM una zona de vasos serpentiginosos, que se extiende desde el subcutáneo hasta la pared anterior del maxilar. La angiografía cerebral confirma MAV de alto flujo e informa mapeo vascular. Se decide embolización prequirúrgica superselectiva con posterior resección tumoral mediante acceso transvestibular. Palabras claves: Malformación arteriovenosa (MAV), alto flujo, embolización superselectiva.

Management of extracranial arteriovenous malformations of the head and neck

The purpose of this study was to review the outcomes of the different therapies for extracranial head and neck arteriovenous malformations (AVMs).AVMs are high-flow congenital vascular anomalies. They are composed of a complex system of vessels directly connecting feeding arteries to draining veins forming a nidus.They may be potentially life-threatening due to progressive symptoms and infiltrative disease. Extracranial AVMs most commonly affect the head and neck area (47.4%) followed by the extremities (28.5%). AVMs are best characterized as being either focal or diffuse. Focal AVMs have good outcomes following adequate treatment. Diffuse lesions have multiple feeding vessel, which results in high rates of recurrence despite treatment.The management of AVMs includes conventional surgery and endovascular techniques. A combination of embolization and surgical resection has become the treatment of choice over the last years. The main goal of both forms of treatment being the complete blockage or resection of the nidus. Transcatheter embolization of vessels has evolved over the years and new embolic agents have emerged. The types of materials available for embolization are classified into mechanical devices, liquid agents and particulates. Efficacy, rate of recurrence and most common complications were evaluated.AVMs recurrence after embolization or resection is reported in up to 80% of cases. Incomplete resection and embolization can induce aggressive growth of the remaining nidus and the risk of progression is up to 50% within the first 5 years and recurrences can occur up to 10 years later.✩ This article was written by members and invitees of the International Head and Neck Scientific Group ( www.IHNSG.com).
