    The aim of this study was to analyze the tortuosity of the vertebral artery and to emphasize the clinical importance of tortuosity. The data derived from this study will add important contribution to our anatomical knowledge, but they will also find clinical applications in radiology and surgery. We examined 40 patients with CT angiography and analyzed the tortuosity of the vertebral artery. Of the vessels examined, 22 (55%) followed a relatively straight course from their origin to their entry into the transverse foramen. The other 18 (45%) patients showed some form of tortuosity. Both vertebral arteries showed high incidence of tortuosity. Our study has highlighted the possible role of vertebral artery tortuosity in diagnostic and surgical procedures in order to prevent vertebral artery injury.

    With the introduction of new techniques in diagnostic and interventional radiology and progress in micro neurosurgery, accurate knowledge of the brain blood vessels is essential for daily clinical work. The aim of this study was to describe the morphological characteristics of the superior cerebellar artery and to emphasize their clinical significance. In this study we examined radiographs of 109 patients who had CT angiography at the University Clinic for Radiology in Skopje, R. Macedonia. This study included 49 females and 60 males, ranging in age from 27 to 83 years; mean age 57.4 ± 11.8 years. In 105 patients SCA arose from the basilar artery on both sides as a single vessel. In two patients SCA arose as a duplicate trunk from the basilar artery. We found unilateral duplication on the right SCA in one patient, and bilateral duplication in one patient. In two patients was noticed origin of the SCA from PCA as a single trunk from adult type of the PCA. Through knowledge of the anatomy and variations of SCA is important for clinicians as well as basic scientists who deal with problems related to intracranial vasculature in daily basis for save performance of diagnostic and interventional procedures.

    The posterior circulation of the brain constitutes the vertebrobasilar system and its branches, which are responsible for about 30% of the brain’s blood supply. The aim of this study was to describe the anomalies of the basilar artery, especially fenestrations. For that purpose, we examined 50 patients with computed tomography (CT) angiography during an 8-month period. In the CT reports of 2 (4%) patients of the 50 analysed, fenestration was found at the proximal basilar trunk. The two fenestrations in our series were not associated with aneurysms. No collateral branches originated from the two limbs of the fenestration. In conclusion, basilar artery fenestrations are a rare finding. The data derived from this study are useful teaching material for anatomists, and for the radiologists and neurosurgeons they are important for diagnostic and intervention procedures such as CT, magnetic resonance imaging, angiography, and surgical and endovascular procedures.

    With the introduction of new techniques in diagnostic and interventional radiology and progress in micro-neurosurgery, accurate knowledge of the brain blood vessels is essential in daily clinical work. The aim of this study was to describe the different types of PCA origin, their diameter, and to emphasize their clinical significance. In this study we examined radiographs of 53 patients who had CT angiography undertaken for a variety of clinical reasons, performed as a part of their medical treatment at the University Radiology Clinic in Skopje, R. Macedonia. This study included 24 females and 29 males, ranging in age from 32 to 73 years; mean age 55.3 ± 11.5 years. The results showed that the diameter of the posterior cerebral artery was 1.74 ± 0.317 mm on the right side and 1.98 ± 0.408 mm on the left side. The adult configuration was present in 37 (69.81%); foetal configuration was present in 12 (22.64%) and transitional configuration was present in 4 (7.54%) of the patients. We found two patients with bilateral foetal type and ten with unilateral foetal type (six on the right side and four on the left side). Despite the limitations of the study, we found that the foetal variant was presented in 22.64% of patients. Thorough knowledge of the anatomy of the intracranial vessels is important to clinicians as well as basic scientists who deal with problems related to intracranial vasculature on a daily basis.

    Because of their anatomical localization, vertebral arteries were neglected in research for a long period of time. Vertebral arteries are responsible for about 30% of the brain blood supply. The aim of this study was to examine the vertebral artery’s course in the first segment, and to define the anatomic variations and percentage of their appearance in the adult population using CT angiography. The data derived from this study may find useful application in a wide range of medical fields, such as anatomy, radiology and surgery. For that purpose during a 6-month period we examined 30 patients with CT angiography. The origin of the vertebral artery in all 30 patients was from the subclavian artery. The diameter of the left vertebral artery was from 1.6– 5.20 mm., average 3.35 mm. The diameter of the right vertebral artery was from 1.64– 5.40 mm., average 3.19 mm. Hypoplasia of the vessel was found in four patients. We found no aplasia of the vessel in this series. A contorted course was found in 12 (40%) patients. In all 30 (100%) patients the vertebral artery entered the foramen transversum at the level of the sixth cervical vertebra. Although the incidence of anatomical variations is rare, their presence is significant in the diagnostic and surgical procedures in the head and neck region. Insufficient knowledge can lead to serious iatrogenic injures.

    Aneurysms represent local pathological enlargement of the brain blood vessels that occur in 5% of the population. Intracranial aneurysms in 20 to 25% of the population are localized on the middle cerebral artery, and almost 80% of them reveal at the bifurcation of the middle cerebral artery. There are a number of open issues that are debated in the scientific community for aneurysms of the middle cerebral artery. The purpose of this paper is to analyze clinical features, diagnostic and therapeutic modalities of aneurysms of the middle cerebral artery. The study population enrolled 17 patients referred to the University Clinic of Neurosurgery in Skopje, R. Macedonia during a 1-year period between January and December 2014. This study included 9 (52.94%) females and 8 (47.05%) males, ranging in age from 40 to 72 years; mean age 54.5±7.78 years. From 17 treated aneurysms, 9 aneurysms (52.94%) were located on the left MCA and 8 aneurysms (47.05%) were located on the right side. Multiple aneurysms were present in 8 patients (47.05%). The diameter of the aneurysms was in range between 3 to 14 mm, mean 7.62 mm ±3.39 mm. The mean value of the aneurysm neck was 3.2 mm. In our group 12 aneurysms (70.58%) were small and 5 aneurysms (29.41%) were medium according to the size. Patients were treated operatively and aneurysm was excluded from circulation by placing permanent clip to the neck of the aneurysm. Morphological analysis and topographical characteristics of the aneurysms of the middle cerebral artery is very important to decide the treatment of the aneurysm. Use of micro neurosurgical clipping is an effective method for the treatment of aneurysms of the middle cerebral artery.

    Aneurysms represent local pathological enlargement of the brain blood vessels that occur in 5% of the population. Intracranial aneurysms in 30 to 37% of the population are localized on the anterior communicating artery. Rupture of aneurysms of the anterior communicating artery lead to subarachnoid hemorrhage characterized by a high rate of morbidity and mortality. There are a number of open issues that are debated in the scientific community for aneurysms the anterior communicating artery. The purpose of this paper was to analyze clinical features, diagnostic and therapeutic modalities of aneurysms of the anterior communicating artery. All patients in this study were treated operatively and aneurysm was excluded from circulation by placing permanent clip to the neck of the aneurysm. Morphological analysis and topographical characteristics of the aneurysms of the anterior communicating artery is very important to decide the treatment of the aneurysm. Use of microneurosurgical clipping is an effective method for the treatment of aneurysms of the anterior communicating artery.
