Item type:Publication, PERSISTENT TRIGEMINAL ARTERY - ANATOMICAL FEATURES AND CLINICAL SIGNIFICANCE(Macedonian Association of Anatomists and Morphologists, 2023); ; ; ; Persistent trigeminal artery is the most common primitive carotid basilar anastomosis that persists in adulthood. The overall incidence of persistent trigeminal artery is between 0.2 to 0.76%. PTA are known to be associated with a wide range of pathology. The aim of this study was to describe the morphological characteristics of the PTA and to emphasize its clinical significance. We examined radiographs from patients who had CT angiography undertaken for a variety of clinical reasons, performed as a part of their medical treatment at the University Institute for Radiology in Skopje, RN Macedonia. The study population included 234 patients, 130 male and 104 females, mean age 57.8 years. In one patient we found PTA with overall incidence of 0.42%. CTA revealed a left PTA that arise from the internal carotid artery and communicate with the basilar artery between the origin of the anterior inferior cerebellar artery and the superior cerebellar artery. Although anatomically interesting, an awareness of the anatomy and variations of the brain arteries is clinically important for radiologists and surgeons for save performance of procedures, and forensic pathologists since variants may have forensic consequences. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Anatomy of middle cerebral artery(Macedonian Association of Anatomists and Morphologists, 2012); ; ; Cerebral circulation, especially arterial, in recent decades has attracted the interest of anatomsits and clinicians. The importance of the cerebral arterial system is due to the exceptional importance of the organ that it supplies and the fact that cerebrovascular pathological processes are the leading place primary cause of morbidity and mortality. The aim of this study was to determine the morphological and topographic characteristics of the middle cerebral artery: shape, position, diameter, length; the number, types and distribution of its branches and the correlation of these vessels with adjacent brain structures. The examination was made on 50 specimens of human brain fixed in 10% formalin. The shape, postion, diameter and length of the middle cerebral artery were assessed, as well as the number, types and distribution of branches and correlation with adjacent brain structures. We present the obtained results and the most common variations. The importance of the MCA is a result of the significance of the structures it supplies. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Anomalous origin of the vertebral artery(Macedonian Association of Anatomists and Morphologists, 2010); ; ; The posterior circulation of the brain consists of the vertebrobasilar system and its branches. Vertebral arteries are responsible for about 30% of brain blood supply. The aim of this study was to examine the origin of the vertebral artery and to present the anatomic variations of the vertebral artery origin as well as the percentage of their appearance in the population. Material and methods: The origin of the vertebral artery was investigated in 30 patients; a total of 60 vertebral arteries were examined with CT angiography and DSA by Seldinger technique. Results: Abnormal origin of the vertebral artery was found in one (3.3%) patient. Vertebral artery originated directly from the aortic arch, as a second branch between left subclavian artery and left common carotid artery. Conclusion: Real abnormality of the origin of the vertebral artery is rare; in our series it was found in 3.3% of the cases. The described variations of the vertebral artery origin are not only interesting from the anatomical point of view, but they also find clinical applications in the surgery and diagnostic and therapeutic radiology. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Anatomy and variations in the origin of the vertebral artery(Macedonian Association of Anatomists and Morphologists, 2011); ; ; ; The vertebral artery (a. vertebralis, VA) is classically described as the first branch of the ipsilateral subclavian artery (a. subclavia), but multiple variations in the origin of that vessel have been reported in the literature. This examination was made on 110 unselected human hearts without pathoanatomical changes, obtained after autopsy of newborns, fixed in 10% formaldehyde. Standard anatomical methods, inspection and dissection were used for the analyzing of the origin of a. vertebralis. The analysis showed that 102 of the specimens (92.7%) had the usual pattern of the aortic arch and its branches, with the usual topographic relations. In three of the specimens (2.7%) a. vertebralis sinistra had a separate origin between a. carotis communis sinistra and a.subclavia sinistra. In one specimen a. vertebralis sinistra had a separate origin as the fourth branch between a. carotis communis sinistra and a. subclavia sinistra and there was a fifth branch originating distal to a. subclavia sinistra. - Some of the metrics are blocked by yourconsent settings
