“…In some cases pontine perforating branches of PTA are observed [3,23,33]. The incidence of PTA varies from 0.1-0.6% [11] and according to some studies is higher in women [5,22]. In most cases the right or none-sided predominance of the PTA is detected.…”

Persistent trigeminal artery as a rare cause of vertebrobasilar insufficiency

et al. 2022

The persistent trigeminal artery (PTA) is the most common fetal carotid-basilar anastomosis which may persist into adult life. In the literature there are numerous papers referring to the anatomical characteristics of this anomalous vessel. In the majority of cases PTA is an incidental finding and its clinical significance has been debated. Some authors describe the coincidence of PTA with various clinical syndromes. However, there are few reports linking PTA with the symptoms of vertebrobasilar insufficiency. We present a patient with a 3-year history of recurrent dizziness and impaired vision, precipitated by physical activity, in whom neuroimaging techniques revealed a persistent left trigeminal artery (PTA). In our case the occurrence of PTA might have been related to the clinical manifestation and the potential mechanism will be discussed.

“…4 A recent angiographic study using 3D time-offlight MRA estimates the prevalence of PTAV to be 0.2%. 22 In another description, Salas et al classified the PTA by its relationship to the abducens nerve (CN VI) into a medial (sphenoidal) type and a lateral (petrosal) type. 8,23 The lateralor petrosal-type PTA originates from the posterolateral aspect of posterior genu segment of the cavernous ICA (C4) and courses lateral under the abducens nerve to penetrate the dura medial to the sensory root of the trigeminal nerve in Meckel cave.…”

Persistent Trigeminal Artery in Endonasal Resection of Skull Base Tumors: A Systematic Review

Primitive persistent trigeminal artery (PTA) is an uncommon embryologic vascular communication between the carotid and basilar arteries, which can be intimately involved by skull base tumors (SBT). Owing to its rarity, skull base surgeons should familiarize themselves with the anatomical variations of PTA to avoid catastrophic complications. To appraise and summarize the available evidence of PTA involved by SBTs while advocating a standardized algorithm for the surgical planning of these patients. MEDLINE and PubMed databases were searched using keywords pertaining to PTA and SBTs. Demographics, clinical presentation, radiographic findings, outcomes, and adverse events were extracted and analyzed. A total of 13 cases between 1973 and 2015 were identified. The mean patient age at presentation was 43 years with predilections toward females and pituitary adenomas. Headaches and endocrine abnormalities were the most common symptoms. The tumors were more frequently associated with Salas medial-type PTA (70%) and Saltzman type-I PTA (31%) than seen in the general population in angiographic studies. We also present a new case of atypical meningioma with Saltzman type-1 PTA. With endoscopic approaches to SBTs becoming more commonplace, surgeons may encounter this anatomical abnormality more frequently. It is important for both otolaryngologists and neurosurgeons to gain a complete understanding of the anatomical variations and neurointerventional capabilities for the successful endoscopic management of these situations.: 4.

“…Previous studies have shown that PPTA may be associated with several cerebrovascular abnormalities. 1 , 3 The PPTA was reported to occur along with a missing carotid artery and occlusion 9 and in combination with hypoplasia of the basilar artery. 1 These appearances support the fact that embryological abnormal development is the probable cause.…”

“… 1 , 2 The advances in neuroimaging techniques have led to the increased detection of PPTA and prompted considerable research interest in its clinical significance. 3 , 4 Studies have shown that in approximately 25% of the cases, PPTA occurs in combination with other cerebrovascular lesions, such as aneurysms, 5 cavernous fistula, and arteriovenous malformation, 6 , 7 which are clinically manifested as trigeminal neuralgia, paralysis of the oculomotor nerve or abducens nerve, or palsy of the trochlear nerve. 2 These conditions can lead to compression of the brain stem and, eventually, cerebral ischemia.…”

Persistent primitive trigeminal artery associated with monocular blindness and external carotid-vertebral artery anastomosis

In this paper, we present 2 rare cases of persistent embryonic anastomoses. In one case, the patient presented with persistent trigeminal artery along with multiple foci of cerebral infarction as well as central retinal artery thrombosis. In the other case, the patient had direct anastomosis of the vertebral artery with ipsilateral external carotid artery as well as pontine infarction, aneurysm, and unilateral hypoplasia of the vertebral artery. The findings in these cases may shed light on the clinical presentation of such persistent anastomoses and aid their detection in clinical settings.
