Introduction. Carotid cavernous fistulas are infrequent vascular malformations that generate a pathological arteriovenous shunt, which compromises ocular function. The definitive diagnosis is established by cerebral arteriography. However, its invasive nature limits its use in follow-up. The aim of this work is to illustrate the value of the study with transcranial doppler ultrasound for the diagnosis of cavernous carotid fistulas and to describe the flow parameters that could be modified. Patients. A retrospective review of the clinical histories of the patients treated with a diagnosis of cavernous carotid fistula was carried out in the stroke unit of the Hermanos Ameijeiras Hospital in Havana, between January 2005 and May 2014. Demographic and disease variables were collected, as well as the results of imaging and ultrasound studies. Results. We describe the clinical and imaging characteristics of three patients in whom carotid cavernous fistula was confirmed. In the two patients with direct communications, an increase of the mean flow velocity in the ophthalmic vein, arterialized, with decrease in pulsatility were registered; in addition to an increase in the diastolic peak velocity in the internal carotid artery ipsilateral to the fistula. In the patient with the indirect fistula the changes were less marked. Conclusion. The ultrasound study was useful in the diagnosis of carotid cavernous fistulas, showing differences in the flow parameters that can be used to classify the fistulas.
