Aortic valve reconstruction with autologous pericardium in a patient with osteogenesis imperfecta
(OXFORD UNIV PRESS, 2018-01-01) Gullu, A. Umit; Senay, Sahin; Ozkan, Basak; Kocyigit, Muharrem; Alhan, Cem
Cardiac valve surgery for patients with osteogenesis imperfecta is associated with a high incidence of complications such as perioperative bleeding and valve detachment. In this report, we present a patient who was diagnosed with osteogenesis imperfecta and severe aortic insufficiency and also discussed treatment options.
Application of cryoablation for the treatment of atrial fibrillation in patients undergoing cardiac surgery: Our mid-term results
(BAYCINAR MEDICAL PUBL-BAYCINAR TIBBI YAYINCILIK, 2018-01-01) Arnaz, Ahmet; Gullu, A. Umit; Akyol, Ahmet; Zencirci, Ertugrul; Senay, Sahin; Degirmencioglu, Aleks; Kocyigit, Muharrem; Alhan, Cem
Background: In this study, we aimed to present mid-term results of concomitant argon-based cryoablation in patients undergoing cardiac surgery. Methods: Between August 2014 and May 2016, 33 patients (17 males, 16 females
Leyla loop: a time-saving suture technique for robotic atrial closure
(OXFORD UNIV PRESS, 2013-01-01) Kilic, Leyla; Senay, Sahin; Gullu, A. Umit; Alhan, Cem
The longer durations of cardiopulmonary bypass and aortic cross-clamp times remain the disadvantages of robotic or minimally invasive cardiac surgery. For this reason, every small contribution to speeding up these procedures is of the utmost importance. Here, we present a practical, easy and time-saving suture technique for atrial closure. It consists of a hand-made loop at one end of the suture and saves the time otherwise consumed by knotting. It may also be used during conventional or minimally invasive cardiac surgery.
Use of bone wax is related to increased postoperative sternal dehiscence
(TERMEDIA PUBLISHING HOUSE LTD, 2014-01-01) Alhan, Cem; Ariturk, Cem; Senay, Sahin; Okten, Murat; Gullu, A. Umit; Kilic, Leyla; Karabulut, Hasan; Toraman, Fevzi
Aim: To investigate the relation between use of bone wax and postoperative sternal dehiscence after cardiac surgery. Material and methods: Five thousnad three hundred and eighteen consecutive patients who underwent cardiac surgery between 1999 and 2009 were evaluated prospectively. Perioperative use of bone wax, perioperative data and outcome parameters were recorded. Multivariate logistic regression analysis was performed to define independent risk factors for postoperative sternal dehiscence. Results: Bone wax was used in a total of 1151 (21\%) patients. Postoperative sternal dehiscence was detected in 88 (1.6\%) patients. The postoperative sternal dehiscence rate was 1.4\% in patients without bone wax and 2.5\% in patients with bone wax (p = 0.001). The rate of bone wax use was 36.4\% in patients with sternal dehiscence and 21.4\% in patients without sternal dehiscence (p < 0.001). Independent risk factors for postoperative sternal dehiscence were defined as: age > 70 (OR = 1.9, 95\% CI: 1.2-3.1, p = 0.005), chronic obstructive lung disease (OR = 2.4, 95\% CI: 1.5-3.9, p < 0.001), use of bone wax (OR = 1.6, 95\% CI: 1.03-2.5, p = 0.03), nonelective operation (OR = 2, 95\% CI: 1.1-3.4, p = 0.009), and body mass index > 30 (OR = 2.2, 95\% CI: 1.4-3.5, p < 0.001). Conclusions: Our findings suggest that use of bone wax may be associated with increased postoperative sternal dehiscence after cardiac surgery. Thus liberal use of bone wax should be restricted.
