    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.

    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.

    A simple method for occlusion of both venae cavae in total cardiopulmonary bypass for robotic surgery
    (OXFORD UNIV PRESS, 2012-01-01) Gullu, Ahmet Umit; Senay, Sahin; Kocyigit, Muharrem; Alhan, Cem
    We describe a novel surgical technique for occlusion of the superior and inferior venae cavae which allows opening of the right atrium safely during robotic cardiac surgery.

    Robotic-assisted beating heart surgery provides precise repair of periprosthetic mitral valvular leak
    (OXFORD UNIV PRESS, 2022-01-01) Kocyigit, Muharrem; Gullu, Ahmet Umit; Senay, Sahin; Alhan, Cem
    The prosthetic paravalvular leak is a rare but important complication following mitral valve replacement. Determining the location of the leak is almost always dependent on perioperative transoesophageal echocardiography and the considerable expertise of echo operators. Acoustic shadowing due to the prosthetic valve may create another important difficulty. In this report, we present a case with a paravalvular leak diagnosed 1 year after mitral valve replacement. Beating heart surgery and robotic 3D/high-resolution camera provided to localize the direct location of leak coherent with perioperative echocardiography and precise repair. The robotic approach prevented the potential complications of aortic cross-clamp and resternotomy. The paravalvular leak is one of the most important complications of mitral valve replacement surgery with a prevalence of 2-13\% {[}1, 2].

    Postoperative Atrial Fibrillation Reduced by Intraoperative and Postoperative Cell Saver System in Coronary Artery Bypass Graft Surgery
    (AVES, 2022-01-01) Kocyigit, Muharrem; Kocyigit, Ozgen Ilgaz; Gullu, Ahmet Umit; Senay, Sahin; Alhan, Cem
    Objective: Postoperative atrial fibrillation is commonly seen after cardiac surgery. One of the contributing factors is mediastinal shed blood and inflammation. Cell salvage techniques can reduce allogenic blood transfusion and reduce inflammation. The aim of this study was to investigate the reduction of postoperative atrial fibrillation by using the cell-salvage system. Methods: Patients who underwent isolated coronary artery bypass graft surgery (n = 498) were analyzed retrospectively in 2 groups. Postoperative atrial fibrillation group (n = 75) and non-postoperative atrial fibrillation group (n = 423). Preoperative and postoperative demographic and clinical data were compared between the 2 groups, respectively. Postoperative atrial fibrillation and possible contributing factors were analyzed with multinomial logistic regression analysis. Results: In the postoperative atrial fibrillation group, the patients' age and European System for Cardiac Operative Risk Evaluation (Euroscore) were higher than in the non-postoperative atrial fibrillation group (P = .001 and P = .003, respectively). Postoperative intensive care unit stay and hospital stay were longer in the postoperative atrial fibrillation group than in the non-postoperative atrial fibrillation group (P =.001 and P = .046, respectively). There were no statistical differences in mortality between groups. The incidence of postoperative atrial fibrillation decreased with the use of cell saver system and low Euroscore. Conclusion: The use of a cell salvage device intraoperatively and during the early postoperative period can decrease the incidence of postoperative atrial fibrillation group.

    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.
