: The circulus arteriosus cerebri of the porcupine was investigated in this study. Five porcupines were used. Coloured latex was given from the left ventricles of three and from the communis carotid artery of two porcupines. The circulus arteriosus cerebri was examined after dissection was done. The basilar artery was formed by a merge of the right and left vertebral artery. The caudal communicans artery which was the caudal part of circulus arteriosus cerebri was formed by the basilar artery on crus cerebri. From caudal to cranial, the branches originating from the basilar artery and circulus arteriosus cerebri to cerebrum and cerebellum were as follows: caudal cerebelli artery, media cerebelli artery, rostral cerebelli artery, caudal choroidea artery, artery which extended to the mesencephalon, caudal cerebral artery, internal ophthalmic artery, rostral choroidea artery, media cerebral artery, rami striati and rostral cerebral artery. The rostral cerebral artery dexter and sinister joined to each other by the rostral communicans artery, forming the circulus arteriosus cerebri. It was determined that the internal carotid artery did not participate in the formation of circulus arteriosus cerebri and the arterial blood to the circulus arteriosus cerebri of porcupine is provided via the basilar artery only.

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.

In this study, the circulus arteriosus cerebri of the ground squirrel (<i>Spermophilus citellus</i>) was investigated. Five ground squirrels were used as subjects. Coloured latex was injected from the left ventriculi of the hearts of all the squirrels. When the vertebral arteries of two of the animals were ligatured, it was found that there was no internal carotid artery. After careful dissection, the circulus arteriosus cerebri (the circle of Willis) was investigated. The right and left vertebral arteries gave rise to the caudal cerebellar artery before forming the basilar artery. The basilar artery formed the caudal communicans artery that was the caudal part of the circulus arteriosus cerebri on the pontocrural groove (sulcus pontocruralis). The caudal, medial, rostral cerebellar, the common root formed by the caudal cerebral and choroid arteries, the rostral choroid, the rostral and medial cerebral arteries arose from the vertebral, basilar and caudal communicans arteries and dispersed to the cerebrum and cerebellum from caudal to cranial. The termination and the branches of the rostral cerebral artery in ground squirrels varied. It was observed that the internal carotid artery does not supply the circulus arteriosus cerebri in ground squirrels.

Objectives: Anatomy of circulus arteriosus cerebri (CAC) shows wide variation in different individuals, and population groups and has vital clinical significance in causation and presentation of clinical disease. The literature revealed a connection between the variations of CAC and cerebrovascular disease, ischemia, stroke, aneurysms, and atherosclerosis. Material and Methods: In this study, 513 patients without clinical manifestation in regard to cerebrovascular diseases, who are considered healthy on CAC anatomy, are included. Patients were instructed by clinicians for head imagery with magnetic resonance angiography examination during 2016–2017 periods. Results: After statistical analysis, 43.27% were male while 56.72% female, 39% were younger than 40 years old. Age interval lies from 11 to 84 years old, mean age 46. The most common variations or 9.74% is when communicant anterior artery absence and absence of both posterior communicant arteries (Type G*/E) more rarely is H*/G (0.2%), G*/D (1.75%), G*/G (0.6%), H*/D (0.4%), H*/E (3.39%), H*/H (0.4%), J*/E (0.6%), while combination J*/D, J*/G, J*/H, G*/H not found. The most often combination is absence of anterior communicant artery and absence of both posterior communicant artery (Type G*/E), more in male 10.36% than female 9.6%. Conclusion: The CAC is considered to play a critical role in preventing future stroke events in patients with absent of any of the arteries. Knowledge on variations in arteries forming the CAC is with clinical significance, as it is one of the components of CAC which stabilizes cerebral blood flow when principle conduits fail. Knowing the structure of arteries provide clinical knowledge to the surgeons before planning neurovascular surgeries.

BACKGROUND: Circulus arteriosus cerebri is the main source of blood supply to the brain; it connects the left and right hemispheres with anterior and posterior parts. Located at the interpenducular fossa at the base of the brain the circle of Willis is the most important source of collateral circulation in the presence of the disease in the carotid or vertebral artery.AIM: The purpose of the research is to study the diameter and length of arteries and provide an important source of reference on Kosovo’s population.METHODS: This is an observative descriptive study performed at the University Clinical Center of Kosovo. A randomised sample of 133 angiographic examinations in adult patients of both sexes who were instructed to exploration is included.RESULTS: The diameters and lengths measured in our study were comparable with other brain-cadaver studies especially those performed by MRA. All dimensions of the arteries are larger in male than female, except the diameter of PCoA that is larger in female (p < 0.05) and length of the ACoA (p < 0.05). Significant differences were found in diameters of arteries between the younger and the older age groups.CONCLUSION: Knowing the dimensions of the arteries of the circle of Willis has a great importance in interventional radiology as well as during anatomy lessons.

Background: Circulus Arteriosus cerebrii, another name for Circle of Willis, establishes a polygonal anastomotic channel between two internal carotid arteries and two vertebral arteries. The arterial circle is located in the interpeduncular fossa, near the base of the brain. It has been established through anatomical and radiological studies that there are anatomical variations in healthy persons. Aim: To evaluate the anatomical variations in arteries of circle of Willis supplying brain through Magnetic Resonance Angiography (MRA) in population of western UP. Methods and Materials: This cross-sectional study included 264 patients who met inclusion criteria. Non-contrast Magnetic Resonance Angiography of Circle of Willis was carried out among the individuals after a written informed consent. Angiography of brain (circle of Willis) scanning protocol consisted of 3-dimensional time of flight Trans axial acquisition. MRA of brain was performed on GE 1.5 TESLA Optima MRI machine. MRA Brain angiography images were viewed for normal pattern of arterial anatomy and their variations. Results: The complete variant in male was 58.9% (n=103) while in females it was 59.6% (n=53). The incomplete variant in male & females was 41.1% (n=72) and 40.4% (n=36) respectively.

This paper studies the features of the circle of Willis and cerebral aneurysm in patients with cerebral aneurysms through films of Multi-slice Computed Tomography (MSCT) at the Department of Radiology, Bach Mai Hospital, from March 2017 to March 2018. The study results show that female/male ratio was 2.37: 1; the number of patients with only one aneurysm accounted for 90.68%; Saccular aneurysm was more common than lozenge-shaped aneurysm; the rate of aneurysm ruptures was 82.35%; the bulge was mainly distributed in the carotid artery (94.6%). The very small bulge (less than 3mm) and the small bulge (3-7mm) were most common and accounted for 33.33% and 49.62%, respectively. The variations of the circle of Willis were very diverse and complex, including 13 forms, four of which were the circle of Willis anterior part variants and nine transformations were the circle of Willis posterior variants. Abnormalities (aplasia, hypoplasia) of the anterior communicating arterial were 8.48% and abnormalities of the posterior communicating arterial were 82.6%. The paper concludes that the abnormal anatomical variations in the circle of Willis can facilitate the early diagnosis and treatment of cerebral aneurysm disease.
