Abstract in Portuguese
As fístulas arteriovenosas da região do seio cavernoso constituem as fístulas carotidocavernosas que podem ser diretas ou indiretas. As indiretas são raras, a sua sintomatologia é variada e o tratamento é controverso. Este estudo compreendeu a análise prospectiva de 44 pacientes portadores de fístulas carotidocavernosas indiretas (FCCI) no período de 01 de janeiro de 1994 e 31 de janeiro de 2004, 42 com etiologia espontânea e dois pacientes com etiologia traumática, sendo estes analisados separadamente. Doze (12) pacientes foram submetidos à conduta expectante e orientados a realizar manobras de compressão carótido-jugular. O tratamento endovascular foi realizado por via arterial, venosa ou combinação dos dois, num total de 30 pacientes. Considerando o grupo inteiro, ocorreu trombose espontânea em aproximadamente 24% dos pacientes. Os sintomas e o aspecto angiográfico após o tratamento evoluíram com melhora ou cura em 100% dos casos, com oclusão completa das FCCI em 63,3%, a grande maioria destes submetidos a apenas um procedimento. Além dos acessos venosos tradicionais aos seios cavernosos, vias de acesso alternativas através da veia oftálmica superior foram realizadas por punção percutânea de veia facial, veia supratroclear ou veia frontal. O material embolizante mais utilizado foi o adesivo tissular líquido, "cola", isoladamente ou em conjunto com outros materiais. Houve complicações transitórias em 13,3% dos pacientes tratados e nenhuma complicação permanente foi observada, o que demonstrou a baixa morbidade deste procedimento

Abstract in English
The arteriovenous fistulas of the cavernous sinus (CS) region constitute the carotid-cavernous fistula, which can be direct or indirect. The indirect type is quite rare, its clinical features is very inespecific and its treatment modalities controversial. Forty-four patients with indirect carotid-cavernous fistulas (ICCF) were studied in a prospective manner between January 1994 to January 2004, 42 with spontaneous etiology and 2 with traumatic etiology, being these analyzed separately. Twelve (12) patients were submitted to a expectant management and instructed to perform carotid-jugular compression. Endovascular treatment was accomplished by arterial approach, vein approach or combination of both, in a total of 30 patients. Considering the entire group, spontaneous thrombosis was observed in approximately 24%. Symptoms and the angiographic features after endovascular treatment improved or disappeared in 100% of the cases, with total obliteration in 63.3%, most of them submitted to just one procedure. Despite the traditional venous routes to the CS, alternative accesses through the superior ophthalmic vein (SOV) were accomplished by percutaneous puncture of the facial, supratrochlear or frontal vein. Liquid adhesive (glue) was the most often embolic material used isolated or with other materials. No permanent complication was observed and only 13,3% of the patients treated cursed with transitory complications, what demonstrated the low morbidity of this procedure
