[ES] Introducci?n y objetivos: Las f?stulas arteriovenosas suelen tener un origen traum?tico, tras traumatismos faciales o heridas en la regi?n parot?dea. Existe poca casu?stica y el objetivo de esta presentaci?n es remarcar la utilidad del eco-doppler como primer m?todo diagn?stico en todo acufeno puls?til. Material y m?todos: Paciente de 40 a?os que acude a nuestra consulta para valorar acufeno derecho puls?til de a?os de evoluci?n, tras accidente de tr?fico. La palpaci?n parot?dea revela una formaci?n nodular intraparot?dea, blanda depresible, rodadera y bien limitada. Tras la otoscopia sin hallazgos valorables, comprobamos una normoacusia y curvas impedanciom?tricas tipo A. Ante la sospecha de alteraci?n vascular solicitamos Eco-Doppler, que confirma una f?stula arteriovenosa y el mismo radi?logo sugiere realizar una angio-resonancia magn?tica confirma una masa que capta intensamente gadol?neo y la existencia de un vaso aferente. Resultados: Con el estudio de imagen se llega al diagn?stico de F?stula Arteriovenosa de localizaci?n parot?dea derecha dependiente de la arteria car?tida externa. Dada la edad de paciente y la escasa sintomatolog?a que la f?stula A-V produce, se decidi? realizar un seguimiento evolutivo. Al a?o se incrementa la sintomatolog?a y la paciente se deriva a radiolog?a intervencionista, que proceden a embolizar el vaso causante y cesa la sintomatolog?a. Discusi?n: Las f?stulas arteriovenosas y los aneurismas traum?ticos falsos son complicaciones de traumatismos vasculares.Su principal etiolog?a se debe a heridas de armas y tambi?n cirug?a vascular reciente. La sospecha diagn?stica es cl?nica. El diagn?stico diferencial incluye angiomas, tumores vasculares parot?deos o de origen neural y aneurismas vasculares. Conclusi?n: La confirmaci?n diagn?stica y posible tratamiento endovascular se realiza por arteriograf?a en casos muy sintom?ticos o gran tama?o de la lesi?n. Tamb?en podr?a plantearse el tratamiento quir?rgico con la divisi?n de la f?stula y la reconstrucci?n de la arteria y la vena, con ligadura de la vena.
[EN] Introduction and objetives: Most of the arteriovenous fistulas have a traumatic origin: Facial injuries of parotid region. There are described a few series and the objetive is remarck the eco-doppler utitlity as the first diagnosic metod in all throbbing tinnitus. Material and metods: We present a 40 years old woman wo consult for a trhobbing tinnitus for years of evolution beforea a traffic accident. Parotid palpation show an intraparotid nodular formation, depressive and delimitated. Before an anodine otoscopy, a normal audition and impedanciometric A tipe curves. We suspect a vascular alteration and an eco-doppler was done; these confirm the aerteriovenous fistula and a magnetic resonance confirms a mass with an afferent artery and collets a lot of gadolineum. Results: We diagnosed an arteriovenous fistula in the parotid region dependant on exteranal carotid artery. The patient tolerated very good the problem and do an annual control. As the tinnitus was worse tolerated, we propossed embolism the aferal vase. Discussion: Arteriovenous fistula and traumatic aneurism are traumatic vassels injuries, caused by white arms, or chirurgical vascular antecedent. Differential diagnosys include angioma, vascular tumors or aneurism. Conclussion: The endovascular approach requieres a previus arteriography and if the lession is very big or very syntomatic coud been opperated on dividing the fistula and reconstruction of artery and venous vassel is doned.
