Carotid cavernous fistula in a patient with coronary artery disease

Carotid cavernous fistulas are abnormal communications between the carotid and cavernous vasculature, with potential for serious neurological and ocular sequelae. There is considerable literature on the neuro-radiological management of carotico-cavernous fistula depending upon their flow status. The coronary artery bypass grafting (CABG) for coronary artery disease (CAD) is a well established method of revascularization. However, the association of carotid cavernous fistula in presence of CAD is an infrequent occurrence. We present a case of coronary artery disease scheduled for bypass surgery, developed spontaneous bilateral carotid cavernous fistulas, highlighting a unique aspect of association between coronary and carotid disease.
