ABSTRACT

Las fístulas carótido-cavernosas son comunicaciones arteriovenosas patológicas entre la arteria carótida interna intravenosa y el seno venoso-cavernoso que la rodea. Un sistema de flujo y presión elevados irrumpe sobre otro de bajo flujo y velocidad. Ello origina los síntomas y signos. La gran mayoría, son resultantes de traumatismos craneales siendo de alto flujo y alta velocidad-fístulas traumáticas o directas; menos comunes son las llamadas fístulas espontáneas o durales localizadas en la duramadre y alimentadas por ramas menígeas provenientes de las arterías carótidas externa, interna o ambas y de las arterias vertebrales. Estas últimas raras veces tienen implicaciones graves para la vida, pero la pérdida visual constituye el mayor riesgo; no obstante, con elevada frecuencia, ocurre la oclusión espontánea, por lo que se impone la observación hasta que la sintomatología justifique el tratamiento. En el curso evolutivo puede ocurrir la trombosis aguda de la fístula y más propiamente de la totalidad de la vena oftálmica superior la que produce un distintivo cuadro de notable agravamiento de los síntomas que en forma contradictoria ocurre antes de la mejoría y reversión de los síntomas, el síndrome de empeoramiento o peoría paradójica. Para ilustrar el síndrome se presentan los casos clínicos de los pacientes


Caroid-cavernous fistulas are pathological arteriovenous communications between the intracavernous internal carotid artery and the cavernous sinus. A system of high flow and pressure bursts over another system of low flow and slow velocity. This causes the symptoms and signs. The vast majority are related with head trauma being high flow and high speed fistulas: traumatic or direct. Less common are the so-called spontaneous or dural fistulas located in the duramater and fed by meningeal branches from the external, internal, or both carotic arteries and the vertebral arteries. These latest rarely have serious implications for life, but visual loss is the greatest risk; however, with high frequency spontaneously occlusion occurs, and then observation imposes until symptoms justified the treatment. During its evolution acute thrombosis of the fistula itself can occur along the entire length of the ophthalmic vein which produces a distinctive and paradoxical worserning and reversal of symptoms, which is called the syndrome of paradoxical worserning. Clinical cases of two patients are presented to illustrate the syndrome

ABSTRACT

The authors report here their own experience about 16 carotido-cavernous fistula cases, managed from 1976 to 1990. The mean age of patients is 30 years with equal distribution in the two sexes. The traumatisme notion is found to be present in 15 case In all cases, exophtalmos constitues the most constant symptom. The carotid arteriography. Was too useful to confirm the clinical diagnosis. The therapeutical management has led to immediat disappearance of all functional signs. As For exophtalmos, the total regression was noted in 10 patients. The mortality rate was 19%

ABSTRACT

Se presenta el caso de un paciente con fístula carotídeo-cavernosa post-traumática, corroborada con angiografía carotídea y tomografía computadoriza. Fue tratado mediante ligadura de la carótida interna. Se describe el cuadro clínico, fisiopatogenia y tratamiento de esta entidad
