    Evaluation of major coronary artery Bifurcation angles with digital angiography: A detailed study of prevalence in the Upper Euphrates Basin
    (Professional Medical Publications, 2022) Deniz, Gulnihal; Kavakli, Ahmet; Kucukukur, Murat; Kose, Evren; Karaca, Ilgin
    Objectives: To investigate the diversity and average values of bifurcation angles in a large population to help develop new methods. Methods: One thousand five individuals (504 females, 501 male) who visited the Cardiology Polyclinic of Firat University Hospital with the complaint of chest pain between 2010 and 2015 were evaluated retrospectively. Bifurcation angle measurements between LMCA-CX, CX-LAD, LMCA-LAD, CX-OM1, CX-OM2, LAD-D1, LAD-D2, RCA-RMD, RCA-RVD and PDA-PL were evaluated in all cases. Results: Bifurcation angles between LMCA-LAD, LMCA-Cx and LAD-Cx branches with > 90 wide angle bifurcations, and Cx-OM1, Cx-OM2, LAD-D1, LAD-D2, RCA-RMD and PDA-PL with <70 Y type bifurcation angle were found to be high in male and female individuals. The RCA-RVD in female individuals was <70 Y-type bifurcation in 14 (2.8%) people, > 70-90 T-type bifurcation in 209 (41.5%) people, and > 90 wide angle bifurcation in 281 (55.8%) people. Results for male subjects were compatible with this. The correlations of all angles were examined. Robust positive correlations (p <= 0.001) were found for the angular measurements between the main branches and the side branches (Cx-OM1, Cx-OM2, LAD-D1, LAD-D2 and RCA-RMD, PDA-PL). Conclusion: With the help of developing technology, we believe that all this coronary angiography data will guide bifurcation stent techniques, which are essential alternatives to bypass.

    Quantitative Evaluation of Normal Aqueductal Cerebrospinal Fluid Flow Using Phase-Contrast Cine MRI According to Age and Sex
    (Wiley, 2017) Oner, Zulal; Kahraman, Aysegul Sagir; Kose, Evren; Oner, Serkan; Kavakli, Ahmet; Cay, Mahmut; Ozbag, Davut
    The aim of this study was cerebrospinal fluid (CSF) flow quantification in the cerebral aqueduct using phase-contrast cine magnetic resonance imaging (PCC-MRI) according to both sexes and three different age groups to obtain normative data. Seventy two volunteers with no cerebral pathology were included in this study. Subjects were divided into three age groups: 20-34 years, 35-49 years, and 50-65 years including equal gender groups. CSF flow's quantitatively evaluation was performed with images that were obtained by 1.5 T Magnetic Resonance (MR) unit from cerebral aqueduct level on the semi-axial plan. Between groups, peak velocity (cm sec21), average velocity (cm/s), forward volume (mL), reverse volume (mL), net forward volume (mL), and average flow over range (ml/ min)values of current flowing through aqueduct and average aqueductal areas were compared. There were no statistically significant differences in CSF flow parameters among different age groups and between sexes (P> 0.05). There was a statistically significant difference in average cerebral aqueduct area between the age group of 50-65 years and the other age groups (P50.002). The average aqueductal area was higher in the age group of 50-65 years. Normal aqueductal CSF flow parameters evaluated with PCC-MRI don't show a significant difference by age and sex. We have achieved the lower and upper values of these parameters would be useful in future clinical studies. The size of aqueductal area may also be explained by atrophy-dependent ventricular system dilatation in the elderly. (C) 2016 Wiley Periodicals, Inc.
