systolic pressure measured through tricuspid regurgitant flow was 32 mmHg. In multislice CT angiography, main pulmonary artery was enlarged and measured to be 55 mm at the level of the aortico- pulmonary window (Figure 1). Left pulmonary artery was 32 mm and right pulmonary artery was 42 mm. The patient underwent endoscopic examination of the larynx and the left vocal cord was found to be fixed in the paramedian position. Surgery was not considered due to existence of Behçet ’s disease, advanced age of the patient and extent of the aneurysm involving both pulmonary artery and its branches. Clinical remission and radiographic resolution were achieved with cyclophosphamide and corticosteroid therapy and the patient was discharged with follow up recommendations. The most common cause of Ortner’s syndrome is left atrial enlargement due to mitral stenosis. Mitral valve prolapse, thoracic aortic aneurysm, aortic dissection, cor pulmonale and pulmonary artery dila- tation secondary to increased pulmonary artery pressure with any reason have also been described in etiology of Ortner’s syndrome. Ortner’s syndrome may arise from various intrathoracic pathologies of heart and great vessels but to the best of our knowledge this is the first report in the literature presenting a case of Ortner’s syndrome due to primary pulmonary artery aneurysm as a feature of Behçet’s disease. Conse- quently, it should be taken into consideration that hoarseness in a pa- tient with Behcet’s disease may develop due to a pulmonary artery aneurysm and further evaluation should be performed. - OP-146 The Relationship Between Parathyroid Hormone Level and Pulmonary Artery Stiffness in Patients with Chronic Kidney Disease.

Background: Pulmonary arterial stiffness (PAS) is a new echocar- diographic parameter, which can be used to estimate the elastic prop- erties of pulmonary arterial vasculature noninvasively. We aimed to assess the elastic properties of pulmonary artery with echocardiography in chronic kidney disease patients without prominent pulmonary hypertension. Material-Method: Fifty-five patients diagnosed as CKD were retrospectively evaluated. Cardiovascular surgery, pulmonary hyper- tension and chronic obstructive disease were defined as exclusion criteria. PAS was calculated according to the following formula as the ratio of maximal flow velocity shift of pulmonary flow (MFV) to pul- monary acceleration time (AcT): PAS (kHz/sec) ¼ MFV/AcT. Results: Mean GFR value was 46.05  23.48 ml/min; mean age was 40.42  15.10 years; mean PTH level was 129.65  125.19. Also, we found that PAS was 9.14  2.40 kHz/sec and there was a moderate correlation between PTH and PAS (r¼ 0.466, p <0.001). In multivar- iate regression analysis, PTH (OR: 0.301, p¼0.015), tricuspide E/A ratio (OR:0.346, p¼0.002) and hemoglobin level (OR¼-0.330, p¼0.008) were found as independent variables of PAS in patients with CKD. Conclusion: We found that pulmonary arterial vasculature is affected in CKD patients without prominent pulmonary hypertension and PTH seems to play a role in this interaction. However, a further study is needed. - OP-147 The Comparison of Long Axis and Short Axis Approaches in Ultrasound-Guided Internal Jugular Vein Catheterization.

Aims: The aim of this study was to compare long axis and short axis approaches in ultrasound-guided internal jugular vein (IJV) catheteri- zation. After obtaining of Institutional Ethics Committee, the random- ized controlled study which countain 64 surgical patients was designed. All participitants were informed about the study and written informed consents were obtained. Methods: The participitants were randomly assigned to 2 groups: group K (n¼32) and group U (n¼32). Patient demographics, comor- bidities, number of attempts, visualization time, completion time of the attempt, total duration, catheter side, vein diameter were measured by ultrasound (US) and complications recorded. Results: In terms of demographics, no statistically difference were found between the groups. In terms of complications, there was no difference between short and long axis groups. The number of attempts in short axis approach was significantly lower compared to the long axis approach (p¼0.013). The first attempt success rate in the short axis approach was statistically significantly higher (p¼0.03) compared to the long axis approach. IJV was cannulated succesfully at the first attempt in 30 patients (93,8%) in short axis group and in 22 patients (68,8%) in long axis group. Long axis group visualiza- tion times were significantly longer compared with short axis group (p¼0.015). In terms of completion time of the attempt, total duration and vein diameters, there was no significant difference between groups. There was no significant difference between right or left side catheterization. Conclusion: In conclusion, we realized that the short axis approach has a higher the first attempt success rate and lower number of attempts compared with the long axis approach and that there is no significant difference between two approaches in terms of process time and com- plications. - OP-148 Augmentation Index and Carotid Hemodynamic Parameters Before and After Carotid Stenting.

Objective: Augmentation index is an important parameter which is used for evaluating arterial stiffness. Arterial stifness is an significant predictor of cardiovascular events. In this study we aimed to evaluate the acute effects of carotis stenting on arterial stifness invasively which calculated by augmentation index and carotid hemodynamic parameters before and after stenting. Methods: Fifty-one patient who were diagnosed as serebrovascular accident and had stenosis above %70 in internal carotid artery which was shown in non invasive tests were included to our study. During carotis angiography systolic blood pressure, pulse pressure, augmenta- tion pressure before and after stenting were investigated.
