AbstractWe present a very rare variation of a persistent primitive hypoglossal artery (PPHA) arising from the internal carotid artery, detected during a diagnostic angiography. A 50-year-old female patient was admitted with an atypical intracranial hematoma in the left frontal lobe. Catheter angiography revealed intracranial vasculopathy with segmental stenoses, a small aneurysm of the right internal carotid artery bifurcation and a “string of beads” appearance of the left carotid artery, consistent with fibromuscular disease. On the left side, a vertebral artery ending in the posterior inferior cerebellar artery (PICA) was detected, whereas on the right side the vertebral artery was aplastic. During selective angiography of the right common carotid artery, a persistent hypoglossal artery was seen supplying the basilar artery. The literature of persistent embryonal carotid-vertebrobasilar anastomosis and their anatomical variations is discussed with respect to clinical importance for ischemia, interventional procedures, and surgery.

Examination of 167 men (the average age 47.3±7.4 years) with a diagnosis of arterial hypertension I-II degree in combination with reflex syndromes of dorsopathies cervical spine was carried out. These patients received basic therapy by ACE inhibitors, b-blockers and were divided randomly into 4 groups. The patients of the 1st group (41 people) received in addition to basic therapy for 18 days, a low-frequency magnetic therapy by means of apparatus of the "ALIMP-1" on the collar area and a puncture of biologically active points by electromagnetic radiation of extremely high frequency (EHF-puncture) by means of the apparatus "Stella-2" in the "scanning" (59-63 GHz); in the 2nd group (42 people) there were the basic medical complex and EHF-puncture, in the 3rd (44 people) – the main medical complex and magnetic therapy; in the 4th (40 people) was conducted only basic treat-ment. After treatment, the volumetric rate of blood flow through the vertebral artery increased in the patients of the 1st group by 1,4 times on the right and by 1,3 times on the left; in the 2nd – by 1,3 times on the right and on the left, in the 3rd – by 1,2 times on both sides, and in the 4th – by 1,1 times; identical changes of this indicator was detected on the internal carotid artery. The resistance index in the vertebral artery decreased to the end of treatment in the 1st group by 17,1% on the right and by 21,1% on the left; in the 2nd – by 16,9% on the right and by 12,4%, while in the 3rd – by 9,0% on the right and by 12,3 on the left, and in the 4th group was 7,2% on the right and 11,3% on the left (p>0.05). Identical values of the index in the internal carotid artery in the 1st group decreased by 20,3% on the right and by 17,4% on the left; in the 2nd group – by 16,4% on the right and by 9,0% on the left, in the 3rd - by 6,9% on the right and by 12,7 on the left, and in the 4th group - by 9,6% on the right and by 11,3% on the left. Unidirectional dynamics occurred in respect of the pulsation index and cerebro-vascular reactivity. The content of nitric oxide in the serum after treatment in the 1st group increased by 1,3 times and has reached to regulatory parameters; in the 2nd and 3rd changes were identical, and in the 4th there was a tendency to improve. The level of endothelin-1 decreased in patients of the 1st group by 1,2 times, in others – the changes were not significant. The level of VWF is decreased in patients of the 1st group by 1,2 times (p<0.05), in other groups there were no significant changes. In the 1st group of patients there were a reduction in thrombin and ADP-aggregation by 1,4 times, in the 2nd and 3rd the parameters has reached to the control parameters, in the 4th there was a tendency to improve. Thus, the inclusion of low-frequency magnetic therapy and EHF-puncture in the medical complexes in pa-tients with arterial hypertension in combination with dorsopathies cervical spine contributes to increase functional reserve of cerebral circulation, to improve of endothelial and hemostatic parameters.

Persistent Primitive Hypoglossal Artery

Objectives Anatomic variations of the extracranial carotid artery are rare. Persistent primitive hypoglossal artery appears with a reported incidence between 0.03% and 0.2%. We report a case of recurrent transient ischemic attacks originating from proximal internal carotid artery stenosis associated with ipsilateral persistent primitive hypoglossal artery and give a review of the existing literature. Methods A 78-year-old patient with a medical history of two previous transient ischemic attacks consulted our emergency department with an acute left hemispheric stroke. Intravenous thrombolysis permitted complete resolution of symptoms. Concurrent Computed Tomography (CT) and Magnetic Resonance (MR) angiography revealed an unstable plaque causing 50% stenosis of the left internal carotid artery with a persistent primitive hypoglossal artery dominantly perfusing the posterior circulation, and bilateral hypoplastic vertebral arteries. Results Uneventful carotid artery stenting using a proximal protection device was performed, and the patient was discharged after 12 days. Six months follow-up was uneventful with a patent stent in the internal carotid artery. Conclusions Treatment of symptomatic carotid artery stenosis in the presence of persistent primitive hypoglossal artery is challenging. Management should be driven by patients’ co-morbidities, the anatomical localization of the lesions and local expertise. In the case of a high origin of the persistent primary hypoglossal artery, carotid artery stenting with the use of a proximal cerebral protection device is probably the preferred and simplest approach.

In this study, the circulus arteriosus cerebri of the squirrel was investigated. Ten squirrel were used. Coloured latex was given from left ventriculi of the all squirrels. Circulus arteriosus cerebri was examined after the dissection was made. The basilar artery was formed by merge of the right and left vertebral artery. The caudal communicans artery which was caudal part of circulus arteriosus cerebri was formed by the basilar artery on sulcus pontocrurale. From caudal to cranial, the branches originated from the basilar artery and circulus arteriosus cerebri to cerebrum and cerebellum were as follows: the caudal cerebelli artery,rami ad pontem, the rostral cerebelli artery, the caudal choroidea artery, the caudal cerebral artery, the internal ophtalmic artery, the rostral choroidea artery, the media cerebral artery, rami striati and the rostral cerebral artery. In squirrels a variability was observed in the branches that the rostral cerebral artery gives, and their endings. It was determined that the internal carotid artery didn’t exist in 4 animals when the right and left vertebral artery were ligatured. It was found that the internal carotid artery didn’t contribute to the arterial blood to circulus arteriosus cerebri and the arterial blood to circulus arteriosus cerebri of squirrels is provided via only the basilar artery.
