Item type:Publication, Morphologic characteristics of sacra associated with assimilation of the last lumbar vertebra(VM Media sp. z o.o. VM Group sp.k., Grupa Via Medica, 2016); ; ; Background: The impact of lumbosacral transitional states on biomechanics of load transmission between the spine and the legs has been sporadically reported. The aims of the study were to identify morphostructural alterations of sacra associated with assimilation of the last lumbar vertebra and to analyse them in the light of their biomechanical impact. Materials and methods: Linear dimensions of sacrum, its body and base and articular surfaces were measured in 31 normal and 41 transitory sacra. Nineteen sacra presented articular and 22 osseous fusion of the last lumbar vertebra. Measured parameters were compared between normal sacra and the two variations of transitory sacra. Results: Sacra with articular fusion of the last lumbar vertebra showed more pronounced concavity of the sacral curvature and wider than long sacral bodies. The first sacral segment was modified, broaden, ventrally wider and elevated. Almost the whole segment bore at its sides auricular surfaces. Very small portion of the segment was non-articular with less pronounced wedging. Sacra with osseous fusion of the last lumbar vertebra showed similar concavity of the sacral curvature as normal sacra, but longer than wide sacral bodies. The ventral sloping half of the newly formed first segment bore auricular surfaces. The non-articular part was enlarged with pronounced wedging. Conclusions: The term "sacralisation" includes both types of transitory sacra with mutually different morphostructural characteristics in contrast to the normal sacra. Analysis of these morphologic variations may help in understanding the different biomechanical properties and patterns of load transmission. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Anatomy of coronary sinus ostium(VM Media sp. z o.o. VM Group sp.k., Grupa Via Medica, 2016); ; ; Background: The coronary sinus is the main cardiac vein and it has become a clinically important structure especially through its role in providing access for different cardiac procedures. Materials and methods: The study was carried out on 100 randomly selected adult human cadaver hearts fixed in 10% formalin. The transverse and craniocaudal diameters of the coronary sinus ostium (CSO) were directly measured. The presence of the Thebesian valve was noted and the anatomical details of the valve were documented in each case in terms of the shape and extent of coverage of the CSO. Results: Considerable variations in the diameter of the CSO were observed. The mean craniocaudal diameter of the CSO was 8.1 ± 1.51 mm, and the mean transverse diameter was 7.67 ± 1.72 mm. Heart specimens without Thebesian valve tended to have larger ostia. The mean craniocaudal diameter and the mean transverse diameter of the CSO were statistically larger in the specimens without Thebesian valves (p = 0.000 and p = 0.001, respectively). Conclusions: The Thebesian valves were observed in 86 hearts, and a wide variety of their morphology was seen. The majority of the Thebesian valves were semilunar in shape (74.42%). The extent to which the valve covered the ostium was variable, including remnant valves that covered < 15% of the CSO (35%), and valves that were large and covered at least 75% of the CSO (22.09%). In 3 specimens the valve completely occluded the ostium. - 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

Item type:Publication, EVALUATION OF SEX-SPECIFIC DIFFERENCES OF ANTHROPOMETRIC VARIABLES THAT WERE USED AS INDICATORS OF NUTRITIONAL STATUS IN MACEDONIAN CHILDREN(Macedonian Association of Anatomists, 2018); ; ; The aim of this study was to evaluatesex-specific differences of anthropometric varibalesthat were used as indicators of nutritional status in Macedonian children aged 5.The study included 226(113boys and 113girls) Macedonianchildren aged 5. We selected 5 anthropometrical parameters to measure (body weight, height, mid upper arm circumferences-MUAC, skinfolds thickness triceps–SFTr and subscapular-SFSc) and in addition according to the standard formulas we calculated: weight-for-age (BW), height-for-age (BH), body mass index-for-age (BMI)mid-upper-arm circumference-for-age (MUAC)and skifolds thikness (SFTr-for-age, SFSc-for-age).In general results have shown sex-specific differences in the examined parameters (BH, BW, BMI) in favour of the boys, with exception of skin-foldsthicknessthatwere higher in girls. Values of the 50th percentile in boys were as follows: 21kg for BW, 115cm for BH, 15.48kg/m2 for BMI,15.5 cm for MUAC, 7mm for SFTr and 4.1mm for SFSc.The values of these parameters in girls were: 20kg for BW,113.5 cm for BH, 15.01kg/m2 for BMI, 7.8mm for SFTrand 4.7 for SFScrespectively.These results can be used as criteria for assessment and detection of deviations in the nutritional status in Macedonian children aged 5. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Disk herniations and cauda equine compression in unilateral and bilateral articular fusion lumbosacral transitional anatomy types(Macedonian Association of Anatomists, 2018-04-12); ; ; ; The relationship between different lumbosacral transitional vertebra (LSTV) types, disc herniations and neural structures compromise has been sporadically reported. The objectives of this study was to evaluate the relationship between articular fusion LSTV types, disc herniations and neural structures compromise. A total of 92 patients with lumbosacral radicular syndrome who underwent MRI examination of the lumbar spine were included in the study. All patients had at least one evaluated disc herniation at the last three mobile levels. These patients were separated in two groups. Study group comprised 58 patients who presented with LSTV (articular fusion type based on Castellvi classification). Additionaly this group was separated in two subgroups; 25 patients with unilateral and 33 of them with bilateral articular fusion LSTV type. Thirty four patients without LSTV were assigned to the control group. There were significantly more disc herniations (92% vs 73.5%, p=.03) and more severe cauda equine compression (12% vs 5.9%) at the level of transition in the LSTV unilateral articular fusion subgroup compared to the control group. At the adjacent proximal level significantly more disc herniations (93.9% vs 73.5%, p=.03) and more severe cauda equina compression (51.5% vs 14.7, p=.012) was observed in the LSTV bilateral articular fusion subgroup compared to the control group. In conclusion, altered morphology and biomechanics in articular fusion LSTV types provoke disc herniations and severe cauda equina compression to occur more frequently compared to the normal lumbosacral junction. - 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
