Background: The aim of this study was to determine the dimensional characteristics and variations in the origin of vertebral arteries (VA). Materials and methods: (Folia Morphol 2016; 75, 1: 33-37)

Objective: The study aimed to investigate anatomical variations in branching pattern and anatomy of the aortic arch, and the prevalence of each type. Methods: Between September 2011 and November 2013, angiographic studies of 270 patients (144 male, 126 female) were analyzed retrospectively for variations in branching pattern and anatomy of the aortic arch. Patient mean age was 59.8 years (range, 13-88). Branching variations were found and divided into subtypes. Patients were also classified according to arch anatomy. Incidence of variations and types of aortic arch were statistically analysed. Results: Analysis of the 270 patients revealed six types of branching pattern. Type I, classical pattern arch with three branches (TB, LCC, LS), was observed in 198 cases (73.3%). Type II (bovine arch), the most commonly observed variation, in which LCC originates from TB, was observed in 58 cases (21.5%). Type III, in which the left vertebral artery arises from the arch, was seen in seven cases (2.6%). Type IV, a combination of types II and III, was observed in three cases (1.1%). Type V, common origin of common carotids, LS and aberrant RS, was found in three cases (1.1%). Type VI (avian type), arch with only two branches, was observed in one case (0.4%). When patients were classified according to aortic arch anatomy, Type 1, Type 2 and Type 3 were observed in 195, 40 and 35 patients respectively. Conclusion: Knowledge of the variations and anatomy of the aortic arch is essential during interventional procedures and neck-thorax surgery.

SummaryObjectives: Migraine is a headache disorder affecting approximately 12% of the population, predominantly female individuals. Migraine has been associated with vascular events such as stroke and cardiovascular disease. The close connection between these vascular disorders and atherosclerosis is well known. Carotid artery intima-media thickness (CAIMT) is a marker for detection of subclinical atherosclerosis. The present study is an analysis of the presence of subclinical atherosclerosis in migraine patients. Methods: CAIMT was evaluated in 25 female migraine patients and 27 female controls using innovative ultrasound (US) radiofrequency (RF) data technology. Mann-Whitney U test was used to compare measurements in patient and control groups. Results: There was a statistically significant difference between mean CAIMT of migraine patients and control group (p<0.005): mean CAIMT was 701±114 μm in migraine patients and 400±64 μm in control group. Conclusion: Migraine patients are more prone to atherosclerosis compared to healthy individuals. CAIMT measurement with sonography can be utilized in follow-up to detect subclinical atherosclerosis.Keywords: Carotid; intima-media thickness; migraine; ultrasound radiofrequency data technology. ÖzetAmaç: Migren, toplumun yaklaşık %12'sini ve ağırlıklı olarak da kadın bireyleri etkileyen bir baş ağrısı bozukluğudur. Migren, inme ve kalp-damar hastalığı gibi vasküler patolojiler ile ilişkilendirilmiştir. Bu vasküler bozukluklar ile ateroskleroz arasındaki yakın bağlantı iyi bilinmektedir. Karotis arter intima media kalınlığı, subklinik aterosklerozun saptanması için bir göstergedir. Biz bu çalışmada; migren hastalarında subklinik aterosklerozun varlığını incelemeyi amaçladık. Gereç ve Yöntem: Karotis arter intima media kalınlığı, 25 kadın migren hastasında ve 27 kadın kontrol grubunda yeni bir teknik olan ultrason radyofrekans-veri teknolojisi ile değerlendirildi. Hasta ve kontrol gruplarında fark varlığını analiz etmek için Mann-Whitney U testi kullanıldı. Bulgular: Migren hastaları ve kontrol grubu arasında ortalama karotis intima media kalınlığı açısından istatistiksel olarak anlamlı fark saptandı (p<0.005). Ortalama karotis intima media kalınlığı migren hastalarında 701±114 mikrometre iken kontrol grubunda 400±64 mikrometre ölçüldü. Sonuç: Migren hastaları, sağlıklı bireylere oranla ateroskleroza daha yatkındır. Sonografi ile karotis arter intima media kalınlığı ölçümü bu hastalarda subklinik aterosklerozun tanınması amacıyla takiplerde kullanılabilir.Anahtar sözcükler: Karotis; intima media kalınlık; migren; ultrason radyofrekans-veri analizi.

T hyroid gland nodules are common findings and palpable nodule prevalence is reported as 3%-7% in the literature (1-3). Nonpalpable thyroid nodules that cannot be detected clinically are seen on ultrasonography (US) in 13%-50% of the population (4). The most important issue in detection of a nodule is how to distinguish between benign and malignant nodules, so that unnecessary surgical procedures on benign nodules can be prevented and surgical removal of malignant nodules can be ensured.Fine needle aspiration biopsy (FNAB) is a minimally invasive and safe diagnostic method to distinguish benign and malignant thyroid nodules, especially when performed under US guidance. The diagnostic accuracy of FNAB in experienced centers is very high; the sensitivity and specificity were reported to be approximately 85% and 99%, respectively (5).According to the literature, FNAB may provide insufficient results in 2%-20% of the nodules (average 15%) based on whether it has been performed under US guidance or not (3). In addition to operator experience, lesion characteristics, lesion and needle localization, guiding method, number of aspirations, needle size, aspiration technique, and accompanying pathologist are among the factors affecting the results of FNAB (6). An insufficient FNAB cytology result leads to a waste of time not only for patients, but also for clinicians, radiologists, and pathologists. Moreover, repeated biopsy procedures increase the cost and the patient anxiety.In this prospective study, we aimed to determine the contribution of 21G vacuum-assisted modified Menghini type needle to diagnosis of US-guided FNAB of the thyroid evaluated by a pathologist at the bedside. Additionally, we aimed to investigate the effect of the needle on patient comfort and examine the relation between the number of aspirations, nodule characteristics, and sufficient material obtainability. PURPOSEWe aimed to determine the contribution of vacuum-assisted modified Menghini type needle to diagnosis of ultrasound-guided fine needle aspiration biopsy (FNAB) of the thyroid evaluated by a pathologist at the bedside. METHODSA total of 147 thyroid nodules in 138 patients (122 women, 16 men) were included in this prospective study. Sonographic features of nodules, number of aspirations, pain and pain severity during the process, hemorrhage, and presence of sample obtained for cell block analysis were recorded and analyzed with the results of aspiration biopsy. RESULTSUsing the 21G modified Menghini type needle, a diagnosis could not be reached in 14.3% of nodules. Adequate samples for cell block analysis were obtained in 47 nodules (32%), 17 of which contributed to the diagnosis. While the difference between diagnostic cytopathology results and the contribution of the cell block were statistically significant, obtainability of cell block samples was not significantly correlated with the number of aspirations or the presence of a cystic component in the nodule. CONCLUSIONFNAB with 21G vacuum-assisted modified Menghini type needle is a safe ...
