Carotid cavernous fistula (CCF) is a condition with abnormal flow from the carotid artery to the cavernous sinus. The characteristic clinical findings are ophthalmic monoplegia, ptosis, exophthalmos, chemosis, Horner\'s syndrome, facial pain, loss of sensation in the distribution of the trigeminal nerve, and headache. Digital subtraction angiography (DSA) is the gold standard modality for evaluating CCF. An 18-year-old patient came with decreased bilateral visual acuity after a traffic accident. CT angiography was performed on the patient and found a dilated right superior ophthalmic vein. CCF is present in the patient. The DSA procedure was performed on the patient, and embolization was performed on the right ophthalmic vein. On post-embolization angiography, the tubular structure is no longer visible, which is bilateral superior ophthalmic vein dilatation.

Congenital coronary artery fistula is a rare coronary anomaly. Its clinical significance focuses mainly on the mechanism of coronary steal phenomenon. A combination of left main (LM) coronary artery-to-main pulmonary artery (MPA) fistula with anomalous origin of right coronary artery from the pulmonary artery (ARCAPA) was encountered in a 3-month-old infant who presented with tachypnea. Evaluation with echocardiography and CT confirmed the diagnosis. The patient underwent surgical ligation of LM-to-MPA fistula with direct reimplantation of ARCAPA to aortic root.

Persistent trigeminal artery (PTA) originates from the posterior bend or lateral wall of the intra-cavernous carotid artery and is the most common occurring type of remnant primitive fetal arteries. In literature, there is limited number of reports on migraine-cephalgia (MC) associated with coexisting PTA. The primitive anastomose arteries that fully belong to the intracranial arterial vascular system are not supposed to perform any supportive functional activity; usually they are subjected to normal biological decay caused by the aging process and metabolic dysfunctions. The hypothesis suggests that these primitive fetal arteries such as PTA may not undergo a fast and structural deterioration but they might be active contributors to a series of mechanisms that can cause a variety of idiopathic complaints. Consequently this would bring a different therapeutic approach other than their surgical removal, which is the accepted option today as a solution for these problems. In this case report, a chronic unilateral MC due to coexisting PTA adjacent to trigeminal nerve is presented. The caliber and location of the PTA was confirmed by a CT-Angiography. The MC treatment was achieved by administration of bio-identical testosterone, human placenta extract (HPE), b-nicotinamide adenine dinucleotide (NADH) and low dose amlopidine.
