Chronic migraine-cephalgia related to trigeminal artery: a case report of innovative regenerative approach

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.

A systematic review on persistent trigeminal artery, in searching for a therapeutic solution to idiopathic and unresponsive trigeminal nerve inflammations and migraines

The rarely diagnosed persistent trigeminal artery (PTA) originates from the posterior bend or lateral wall of the intracavernous carotid artery and is the most common occurring type of remnant primitive fetal arteries. Even if PTA is uncommon, information and awareness about it could be of great help for clinicians dealing with cranial vascular imaging and operating this region. In addition, it could give a supporting response to the presence of a wide range of idiopathic and unresponsive disturbs that sometimes are erroneously interpreted and treated. There are very few published scientific reports of coexisting PTA and unilateral trigeminal neuralgia and migraine-cephalgia (MC). In this review we describe few reported and unreported cases regarding the manifestation of unresponsive trigeminal neuralgia and migraine due to the presence of PTA. Patients usually present with a clinical symptomatology with unstable blood hypertension, pain of typical trigeminal neuralgia and MC that cover unilaterally the occipital area over the second and third divisions of the nerve. The outbreaks may often become more severe during physical exertion, stress and hypertension. Angio-MRI may reveal the PTA with an occasional occurrence of parietal cavernoma. We also describe a case of chronic left MC case associated with an adjacent PTA close to the trigeminal nerve position. The size and location of the PTA was confirmed by a CT-Angiography. The MC was safely treated by bio-identical testosterone, human placenta extract (HPE), b-nicotinamide adenine dinucleotide (NADH) and low dose amlopidine. It is hypothesized that these types of primitive anastomose arteries that fully belong to the intracranial arterial vascular system do not perform any supportive functional activity. Nevertheless, they undergo the normal biological decay caused by the aging process and metabolic dysfunctions. Therefore, such primitive fetal arteries as PTA might be subjected not only to a faster structural deterioration but they would actively contribute to a series of mechanisms causing a variety of idiopathic intracranial vascular and structural symptoms. Consequently, this would change the primary therapeutic approach to solve this problem, today represented by surgical removal. Anatomic implications related to treatment procedure are also discussed.
