    The Assessment of Hepatosteatosis in Living-Donor Liver Transplant: Comparison of Liver Attenuation Index and Histopathologic Results
    (Baskent Univ, 2017) Kahraman, Aysegul Sagir; Karakas, Hakki Muammer; Kirimlioglu, Hale; Kahraman, Bayram; Yilmaz, Sezai; Kirimlioglu, Vedat
    Objectives: The purpose of the study was to determine the diagnostic value of computed tomography densitometry in the quantification of hepatosteatosis. Materials and Methods: Fifty-one potential liver donors, ranging in age from 19 to 52 years (mean age: 32.4 years +/- 10.2), participated in the study. The mean hepatic attenuation and mean splenic attenuation were determined using regions of interest measurements. The difference between the mean hepatic attenuation and mean splenic attenuation (or liver attenuation index), with liver attenuation index = mean hepatic attenuation - mean splenic attenuation were calcu lated. Computed tomography densitometric para meters were correlated with histopathologic results. Results: From the histopathologic analysis, the degree of macrovesicular hepatosteatosis was 0% to 8% (mean: 1.1% +/- 2%). Seven donors (13.7%) had a degree of macrovesicular steatosis of > 5%, and 12 donors (23.5%) had >= 2%. Of the 29 normal donors with histopathologic verification, computed tomography densitometry predicted <= 5% of the hepa to steatosis in 27 donors, and >= 2% hepato-steatosis in 2 subjects. The liver attenuation index was sig nificantly correlated to the histopathologic results. The mathematical relation between liver attenuation index and the degree of histopathologic hepatosteatosis was calculated using the least-squares methods, which provided quadratic polynomials. Conclusions: Computed tomography densitometry is a rapid, robust, noninvasive technique for the assessment of hepatosteatosis. When used in conjunction with clinically stable reference measurements of spleen, the density measurements of liver correctly predicted the presence of fatty infiltration with significant sensitivity (77%) and specificity (75%). This technique, which was refined during the course of our liver transplant program, minimizes the need for highly invasive percutaneous liver biopsies.

    Canlı vericili karaciğer naklinde (CVKN) radyolojik değerlendirme: segment 4 arteri varyasyonlarının sol lob volümünün total karaciğer volümüne olan oranına etkisi
    (2016) Kahraman Sağır, Ayşegül; Özdemir Maraş, Zeynep; Kahraman, Bayram; Görmeli, Ayşe Cemile; Yılmaz, Sezai
    Öz: Amaç: Bu çalışmada amacımız canlı vericili karaciğer naklinde (CVKN) segment 4 arteri çıkış yeri varyasyonlarının sol lob ağılığı-total karaciğer ağırlığı oranı üzerine etkisinin olup olmadığını araştırmaktır. Gereç ve Yöntem: Toplam 136 verici adayının (70 erkek, 66 kadın) çok-fazlı BT görüntüleri elde edildi. Bireylerin ortalama yaşı 32,6±9 (19 ile 53 arasında) bulundu. Hepatik arterler, elde edilen ince kesit görüntülerin hacimsel gösterim teknikleri ile işlenmesi ile değerlendirildi ve segment 4 arteri çıkış yerleri not edildi. Tüm olgularda toplam karaciğer, sağ lob ve sol lob volümleri ölçüldü. Sol lob ağırlığının total karaciğer ağırlığına oranı (rezidü) hesaplandı ve olgular bu orana göre iki gruba ayrıldı. Bu oranın >= 30% olduğu Grup 1'de 78 olgu, < %30 olduğu Grup 2'de 58 olgu yer aldı. Bulgular: Segment 4 arteri olguların 85'inde sol hepatik arterden, 51'inde ise varyasyonel olarak diğer arterlerden çıkış göstermekteydi. Gruplar arası karşılaştırmalarda total volümler (p=0,775) arasında anlamlı fark bulunmazken, sağ lob (p=0,003) ve sol lob (p=0,000) volümleri arasında anlamlı farklılık saptandı. İki grup arasında Sg4A çıkış yeri varyasyonlarının anlamlı değişiklik göstermediği saptandı (p=0,82). Cinsiyete göre yapılan karşılaştırmada kadın olgularda daha fazla rezidü olduğu bulundu (p=0,013). Sonuç: Sonuçlarımız segment 4 arteri çıkış yeri varyasyonlarının sol lobun total karaciğer volümüne etkisinin olmadğını göstermekte olup daha kapsamlı ileri çalışmaların gerekliliğini ortaya koymaktadır.

    Congenital Agenesis of Right Internal Carotid Artery: A Report of Two Cases
    (Ubiquity Press Ltd, 2016) Kahraman, Aysegul Sagir; Kahraman, Bayram; Ozdemir, Zeynep Maras; Dogan, Metin; Kaya, Mehmet; Gormeli, Cemile Ayse; Durak, Mehmet Akif
    Congenital unilateral agenesis of the internal carotid artery (ICA) is a rare anomaly. Due to proper sufficient collateral circulation via the circle of Willis most cases are asymptomatic, but patients can also present with ischemic or hemorrhagic cerebrovascular insults. The absence of the bony carotid canal is essential to differentiate this anomaly from chronic ICA occlusion. Awareness of this situation by clinicians and radiologists is essential because these patients have an increased incidence of various intracranial pathologies. We report two cases of this rare developmental congenital abnormality occurring in two young patients and describe the presentation, diagnosis, determined developmental causes, imaging findings, and complications.

    Diffusion-weighted imaging (DWI) of the liver in assessing chronic liver disease: effects of the presence and the degree of ascites on ADC values
    (Springer, 2016) Kahraman, Aysegul Sagir; Kahraman, Bayram; Ozdemir, Zeynep Maras; Gormeli, Cemile Ayse; Ozdemir, Fatih; Dogan, Metin
    Purpose: The aim of this study was to determine the correlation between the liver and spleen apparent diffusion coefficient (ADC) values of patients with chronic liver disease and the presence and the degree of ascites. Materials and method: In this retrospective study, we assessed 107 patients with chronic liver disease and 39 control subjects who underwent upper abdominal MR imaging including echo-planar diffusion-weighted imaging (DWI). Among the 107 cirrhotic patients, 56 were classified as group 1, 25 as group 2, and 26 as group 3 according to the absence, the presence of minimal, and the presence of massive ascites, respectively. The scores of model for end-stage liver disease (MELD) were matched between groups as the standard reference. The liver ADC, spleen ADC, and normalized liver ADC values were compared between the control group and patients' groups. Results: Patients with massive ascites had significantly higher MELD score compared with the other groups. The MELD score was also significantly higher in patient groups than in control group. The liver and normalized liver ADCs of patients' groups were significantly lower than that of the control group. With some overlap among groups, the measured ADC values decreased as the amount of the ascites increased, and these relationships were statistically significant. Furthermore, compared to control group, patients with massive ascites had significantly higher spleen ADCs. Conclusion: Our results indicate that the ADC value of the liver and spleen correlates with the presence and the degree of ascites in patients with chronic liver disease, and merits further study.

    Dynamic contrast enhanced magnetic resonance imaging findings of mass lesions of the pontocerebellar angle
    (Kulak Burun Boğaz İhtisas Dergisi, 2007) Fırat, Ahmet Kemal; Karakaş, Muammer Hakkı; Kahraman, Bayram; Fırat, Yezdan; Altınok, Tayfun; Kızılay, Ahmet
    The differential diagnosis of mass lesions of the pontocerebellar angle is not always possible by conventional magnetic resonance imaging (MRI). In this study, we investigated the role of dynamic contrast-enhanced MRI in the differential diagnosis of acoustic neurinoma, meningioma, and paraganglioma. Twelve patients (8 females, 4 males; mean age 47.5 years; range 8 to 71 years) whose diagnoses were acoustic neurinoma (n=3), paraganglioma (n=5), and meningioma (n=4) were evaluated by simultaneous conventional and dynamic contrast-enhanced MRI. Prior to postcontrast T1-weighted images, dynamic MRI was obtained. On these images, maximum contrast enhancement (Cmax) and time to peak enhancement (Tmax) were calculated at 15 different time points. Time-signal intensity curve patterns of the lesions were compared. According to the four main time-signal intensity curve patterns described in the literature, acoustic neurinomas, meningiomas, and paragangliomas exhibited type C, type A-B, and type A curve patterns, respectively. Our results suggest that dynamic contrast MRI may have an additional but limited role in the differential diagnosis of extra-axial intracranial tumors such as those of the pontocerebellar angle.

    Effects of acute exercise on the diameter of the spermatic vein, and duration of reflux in patients with varicocele
    (Informa Healthcare, 2013) Atar, Murat; Soylemez, Haluk; Oguz, Fatih; Beytur, Alt; Altunoluk, Bulent; Kahraman, Bayram; Islamoglu, Yahya
    Objective. The aim of this study was to investigate the effects of acute exercise on the diameter of the spermatic vein, and on the duration of reflux in patients with varicocele. Material and methods. The study included 38 patients with complaints of infertility and scrotal pain between 2009 and 2010. The diagnoses were made by physical examination and colour Doppler ultrasound, with both performed before and after exercise tests. Results. The mean age of the participants was 25.7 +/- 4.9 years. During the first examination, the grades of the varicoceles detected were as follows: grade I, n = 7; II, n = 10; and III, n = 21. The diameters of veins in patients with grades I, II and III varicocele were 2.1 mm, 2.9 mm and 4.2 mm, respectively, before exercise, whereas they were 2.6 mm, 3.2 mm and 4.3 nun, respectively, after exercise. In patients with grade I varicoceles, compared with pre-exercise values, the diameter of the left spermatic vein and duration of reflux measured during Valsalva manoeuvres were increased significantly after exercise (p = 0.042 and p = 0.034, respectively); similar results were obtained for the patients with grade II varicoceles (p = 0.007 and p = 0.008, respectively). However, the minimal relative increase in cases with grade III varicoceles was not statistically significant (p > 0.05). Conclusions. This study demonstrates that acute exercise increases the spermatic vein diameter and reflux time in patients with varicoceles. These outcomes demonstrate that acute exercise may be an aggravating factor for varicocele, as seen in chronic exercise.

    Incidentally Detected Myocardial Cleft: Cardiac Computed Tomography and Magnetic Resonance Imaging Findings
    (2016) Görmeli, Ayşe Cemile; Yağmur, Jülide; Özdemir Maraş, Zeynep; Kahraman Sağır, Ayşegül; Kahraman, Bayram; Özdemir, Ramazan
    Abstract: Myocardial clefts are congenital anomalies, usually localized in the basal inferior wall of the left ventricle and mid-apical segments of the interventricular septum. The patients with genetic mutations related to hypertrophic cardiomyopathy showed significant elevation in the incidence of myocardial cleft. Also there is a significant correlation between the myocardial clefts and the carriers of hypertrophic cardiomyopathy gene mutations without clinical signs. Magnetic resonance imaging allows us to diagnose the myocardial clefts of the healthy individuals as well as the patients and closely follow up for clinical hypertrophic cardiomyopathy. Here we present the cardiac computed tomography and magnetic resonance imaging findings of a case with myocardial cleft

    Intraosseous lipoma presenting as a sphenoid sinus mass
    (Eur Rev Med Pharmacol Sci, 2011) Doğan, Metin; Kahraman, Ayşegül; Fırat, Cemal; Kahraman, Bayram; Karataş, Erkan; Kızılay, Ahmet
    – Intraosseous lipoma is an uncommon mesenchymal tumor that is frequently found in appendecular skeleton. In extremely rare conditions, it can appear in sphenoid bone, and only 2 cases have been described in literature until now. We present a case of lipoma in the body of the sphenoid bone mimicking sphenoid sinus tumor. A 16-year-old man presented to Department of Otorhinolaryngology with a complaint of nonspecific headache. There were any clinical findings on physical examination. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed and the diagnosis was made on these imaging findings. Other diagnostic technique, invasive histopathological assessment was not necessary. To our knowledge, this is the first case of lipoma in the body of the sphenoid bone with indentation to sphenoid sinus. The patient has been followed-up radiologically without the need for surgery for two years.

    Öz: Amaç: Pontoserebellar köşe tümörlerinin konvansiyonel manyetik rezonans görüntüleme (MRG) ile ayırıcı tanısı her zaman mümkün olmayabilir. Bu çalışmada, dinamik kontrastlı MRG'nin akustik nörinom, meninjiyom ve paragangliyom ayırıcı tanısındaki rolü araştırıldı. Hastalar ve Yöntemler: Tanıları akustik nörinom (n=3), paragangliyom (n=5) ve meninjiyom (n=4) olan 12 olguda (8 kadın, 4 erkek; ort. yaş 47.5; dağılım 8-71) konvansiyonel MRG ile eşzamanlı dinamik MRG uygulandı. Bu olgularda kontrast sonrası T^ A sekanslar öncesinde dinamik MRG elde edildi. Görüntülerde 15 ayrı zaman noktasındaki rölatif ve maksimum rölatif tepe kontrastlanma (Kmaks) değerleri ve bu değerlere erişmek için geçen süre (Zmaks) hesaplandı. Lezyonlarm zaman-sinyal intensite eğri paternleri karşılaştırıldı. Bulgular: Literatürde tanımlanan dört temel zaman- sinyal intensite eğrisine göre, akustik nörinomların tip C, meninjiyomların tip A ve tip B, paragangliyomların ise tip A ile uyumlu patern gösterdiği görüldü. Sonuç: Dinamik MRG'nin pontoserebellar köşe tümörleri gibi, ekstra-aksiyal intrakraniyal patolojilerin ayrıcı tanısında sınırlı da olsa katkısı olabileceği düşünüldü.

    Çevresel kontrastlanma intrakraniyal apselerin başlıca görüntüleme bulgusudur. Bu bulgu tedavi sonrası izlenen klinik düzelmeye ve lezyon boyutundaki azalmaya rağmen devam etmektedir. Bu çalışmada akut pansinüzit sonrası frontal lobda 3cm büyüklükte iki apse gelişen 45 yaşındaki bir olgunun tedavi sırası ve sonrasındaki izleminde difüzyon ağırlıklı görüntülemenin kullanımı sunulmaktadır. Cerrahi ve tıbbi tedavi sonrası lezyonların boyutları küçülmekle birlikte apse lojlarındaki kontrastlanma devam etmiştir. Difüzyon ağırlıklı görüntülerde ise tedavi öncesi izlenen kısıtlanmış difüzyonun kaybolduğu saptanmıştır. Apselerde izlenen patolojik kontrastlanma tedavi sonrası yanıltıcı yorumlara neden olabileceğinden, izlemde difüzyon ağırlıklı görüntüler birincil önem taşımalıdır.

    Prospective evaluation of the alterations in the morphology and vascular resistance of the renal parenchyma with color Doppler ultrasonography after percutaneous nephrolithotomy
    (Mary Ann Liebert Inc, 2008) Kilic, Sueleyman; Oguz, Fatih; Kahraman, Bayram; Altunoluk, Buelent; Ergin, Hueseyin
    Purpose: To evaluate the kidneys with color Doppler ultrasonography (CDUS) to determine whether percutaneous nephrolithotomy (PNL) causes renal parenchymal damage. Patients and Methods: In 24 patients who underwent unilateral PNL with single renal pole access, cortical thickness, echogenicity, and resistive index (RI) were measured in each pole of the operated and contralateral kidney separately before and at postoperative day (POD) 1, and at 3, 6, and 12 months after PNL. Results: The mean age of the patients was 36.67 +/- 14.68 years. The serum creatinine level increased significantly immediately after PNL but diminished to the preoperative level at POD 1. Changes in serum blood urea nitrogen and electrolyte levels were insignificant. Mean cortical thickness increased significantly in the access pole and contralateral kidney and insignificantly in the nonaffected pole. No statistically significant change was recorded in parenchymal echogenicitiy. Statistically significant differences in cortical thickness between the access pole and the contralateral kidney and between the nonaffected pole and the contralateral kidney disappeared 3 months later. Differences in mean cortical thickness between the access pole and the nonaffected pole were insignificant at all examination periods. Echogenicity was greater in the access pole and the nonaffected pole than in the contralateral kidney only at POD 1. No significant difference was noted in the echogenicity between the access pole and the nonaffected pole. Mean RIs were lower than the universally accepted pathologic RI level (0.70) at all periods. There was no statistically significant difference between the mean RI values of the access pole, nonaffected pole, and contralateral kidney. Conclusion: PNL does not cause obvious renal dysfunction and significant parenchymal scarring, which is indicated by the decrease in cortical thickness and increases in cortical echogenicity and intrarenal RI.

    Radiological evaluation in living donor liver transplantation (LDLT): the effets of variations in segment 4 artery on the ratio of left lobe volume to total liver volume
    (Turgut Özal Tıp Merkezi Dergisi, 2016) Kahraman, Ayşegül Sağır; Özdemir, Zeynep Maraş; Kahraman, Bayram; Görmeli, Ayşe Cemile; Yılmaz, Sezai
    Abstract Aim: The aim of this study was to evaluate whether the variations in the origin of the segment 4 artery effects the left liver lobe volume ratio to the total liver volume in living donor liver transplantation (LDLT). Material and Methods: Multiphasic CT images were obtained in 136 potential donors (70 men, 66 women). The mean age was 32.6±9 years (ranging from 19 to 53). Volume-rendering techniques were used to evaluate hepatic arteries. The origins of the segment 4 arteries were noted. The volumes of the right lobe, the left lobe and the total liver were measured in each case. The ratios of the left lobe volume to the total liver volume were calculated and subjects were divided into two groups based on this ratio. There were 78 cases with this ratio of ≥ 30 % and 58 cases with this ratio of < 30% in Group1 and Group 2, respectively. Results: The origins of the segment 4 artery were left hepatic artery in 85 cases and variational in 51 cases. The significant difference was shown in right (p=0,003) and left lobe (p=0,000) volumes between two groups whereas not shown in total liver volumes (p=0,775). No significant difference was observed in origins of segment 4 arteries between two groups (p=0,82). Women significantly have greater ratios of left lobe volume than men (p=0,013). Conclusion: Our results indicate that the variations in the origin of the segment 4 arteries have no effects on the ratio of left lobe volume to total volume, and merits further study. Keywords: Living Donor Liver Transplantation; Volumetric Analysis; Hepatic Arterian Anatomy.

    Renal interlobar artery parameters with duplex Doppler sonography and correlations with age plasma renin and aldosterone levels in healthy children
    (AJR, 2006) Sığırcı, Ahmet; Hallaç, Tarık; Akıncı, Ayşehan; Temel, İsmail; Gülcan, Hande; Aslan, Mehmet; Koçer, Muzaffer; Kahraman, Bayram; Alkan, Alpay; Kutlu, Ramazan
    The objectives of this study were to compare and make correlations between age and Doppler parameters of the interlobar arteries, including synchronously obtained plasma renin and aldosterone levels and to obtain new normative data regarding acceleration time in healthy children from neonates to 16 years. One hundred sixty-nine healthy children (72 girls and 97 boys) were classified into four groups: group 1 (< 1 year; n = 34), group 2 (range, 1–6 years; n = 48), group 3 (range, 6–12 years; n = 50), and group 4 (range, 12–16 years; n = 37). Blood samples from the renin and aldosterone were collected in the morning after bed rest and fasting. The resistive index (RI), pulsatility index (PI), and the acceleration time of the renal interlobar arteries with duplex Doppler sonography, including both kidney longitudinal lengths with grayscale sonography, were evaluated. One-way analysis of variance with the least significant difference post-hoc test and Pearson’s correlation test were used to compare the differences between groups and to make correlations, respectively. An independent-sample t test was used to evaluate the differences between all parameters based on sex and to compare the left and right kidney longitudinal lengths in each group. The RI, PI, and acceleration time were statistically significant in betweengroup comparisons. Only in group 4 was acceleration time not statistically significant compared with groups 2 and 3. Plasma renin levels were significantly higher in group 1 compared with groups 2 (p < 0.03) and 4 (p < 0.0001); in group 2 compared with group 4 (p < 0.05); and in group 3 compared with group 4 (p < 0.01). The plasma aldosterone levels were significantly higher only in group 1 compared with groups 2 (p < 0.001), 3 (p < 0.008), and 4 (p < 0.0001). The RI correlated linearly with the PI, plasma renin levels, and aldosterone levels and correlated inversely with acceleration time. Age had a negative correlation with the RI, PI, plasma renin levels, and aldosterone levels and correlated positively with acceleration time. There were no statistically significant differences between all parameters based on sex and no significant difference found between the right and left kidney longitudinal lengths in each group. The RI in children up to 54 months old is higher than in adults. Therefore, the adult mean renal RI criterion of 0.70 should be applicable to children 54 months old and older. We showed that the age dependency of the RI was directly related to that of plasma renin and aldosterone levels in healthy children in whom Doppler parameters and blood analysis were evaluated synchronously.
