Item Electron Microscopic Comparison of Radial Artery Grafts in Non-Diabetic and Diabetic Coronary Bypass Patients(WILEY, 2016-01-01) Gursoy, Mete; Guzel, Elif; Erturkuner, Pelin; Cakir, Idil; Duygu, Egemen; Gulcan, Fusun; Hokenek, A. FarukObjective: We compared electron microscopic histologic changes of the radial artery grafts in non-diabetic and diabetic patients. Methods: Thirty-six patients were divided into three groups according to their diabetic status (Group I had no diabetes mellitus {[}DM], Group II had type two DM and HbA1c levels were <7.5\%, and Group III had type 2 DM but HbA1c levels were >7.5\%). Distal parts of radial artery grafts were evaluated with scanning electron microscopy in a blind fashion by two histologists. Electron microscopic scores were compared among the groups. Results: Radial artery electron microscopic scores were significantly different between group 1, 2 and 1, 3 and 2, 3 (p = 0.028, p<0.001, and p<0.001). In linear regression analysis, duration of DM (p = 0.027) and fasting plasma glucose (p = 0.001) were found as independent risk factors for histologic changes of radial artery grafts. Conclusion: Duration of DM and poor glycemic control were found to be associated with radial artery electron microscopic changes.Item A Giant Dissecting Aneurysm of Ascending Aorta Following Aortic Valve Replacement(HINDAWI LTD, 2014-01-01) Hokenek, Faruk; Gursoy, Mete; Gulcan, Fusun; Duygu, Egemen; Fener, MuratAscending aortic dissection and aneurysm are rare but life-threatening complications after aortic valve replacement. Preoperative evaluation of risk factors such as aortic diameter, structural features of aortic wall, and associated diseases may decrease complication rate. We herein present analysis of risk factors of proximal aortic events following aortic valve replacement based on patient with giant dissecting aneurysm who underwent modified Bentall procedure.
