    (Springer Berlin Heidelberg, 2015) Dönmez G.; Dilicikik U.; Aydog S.T.; Evrenos M.K.; Tetik O.; Demirel M.; Doral M.N.
    Muscle injuries among athletic population are common and often occur during sportive activities or training. Most sports-related muscle injuries involve strains, contusions, and uncommonly ruptures. These injuries are responsible for a large proportion of time lost to competition, and particularly for all professional athletes, rapid return to training and competition is a priority. This chapter will discuss the etiology, risk factors, classification, treatment, and possible complications of common types of muscle injuries under the lights of current literature and recent trends. © Springer-Verlag Berlin Heidelberg 2012, 2015, All Rights Reserved.

    Ultrasound-guided catheter-directed foam sclerotherapy for great saphenous vein
    (Edizioni Minerva Medica, 2015) Kurdal A.T.; Yildirim F.; Ozbakkaloglu A.; Iskesen I.; Tetik O.
    Aim: The problem of varicose veins in the lower leg is a common disease and associated with long-term morbidity. It has usually been treated using high ligation with stripping and endovenous ablation surgery of the great saphenous vein. The aim of this paper is to report our own series of patients treated by ultrasound guided catheter directed foam sclerotherapy for the chemical ablation of great saphenous vein. Methods. The study involved 108 legs with symptomatic varicose veins (C2-4) secondary to great saphenous vein insufficiency. The great saphenous vein was accessed at knee level. With the method of Tessari sclerosant foam was made (2 mL 3% polidocanol and 8 mL air) and delivered along the great saphenous vein while the catheter was withdrawn. At two and fifty two weeks after treatment the patients were evaluated. Results. Catheter-directed foam sclerotheraphy was successfully performed in all of the patients. Venous Clinic Severity Score was reduced significantly (P<0.05). Eighty nine percent of the GSV were completely occluded, 4% were partly occluded and 7% were recanalized. No serious side-effects occurred. Conclusion. Catheter-directed foam sclerotheraphy is a safe, simple and minimally invasive procedure. Patient satisfaction was good and the occlusion rate is promising after a single treatment.

    Comparison of amiodarone and propafenone for maintenance of stable sinus rhythm after bipolar radiofrequency ablation combined with a mitral valve procedure in patients with mitral valve disease and persistent atrial fibrillation
    (Baycinar Medical Publishing, 2015) Beşir Y.; Gökalp O.; Yetkin U.; Çelik E.; Iner H.; Lafçi B.; Tetik O.; Gürbüz A.
    Background: This study aims to examine the effects of amiodarone versus propafenone for maintenance of stable sinus rhythm after left atrial bipolar radiofrequency ablation combined with a mitral valve procedure in patients with mitral valve disease and persistent atrial fibrillation. Methods: The study included 75 patients (29 males, 46 females; mean age 66,8±7.4 years; range 54 to 82 years) who underwent left atrial bipolar radiofrequency ablation combined with mitral valve surgery between July 2008 and July 2010. Patients were divided into three groups of 25: propafenone group (group 1), amiodarone group (group 2), and control group (group 3). Atrial fibrillation patients with slow ventricular response were excluded from the study. Results: Data was collected at preoperative period, during surgery, prior to discharge from hospital, and at 3, 6, and 18 months after discharge. Patients from all groups were followed for 18 months. In group 1, the number of patients in sinus rhythm was 22 at discharge, 20 at three months, and 21 at six and 18 months. In group 2, the number of patients in sinus rhythm was 18 at discharge, 13 at three months, 15 at six months, and 16 at 18 months. In group 3, the number of patients in sinus rhythm was 16 at discharge, 11 at three months, 12 at six months, and 14 at 18 months. Group 1 had a statistically significantly higher rate of stable sinus rhythm. No hospital mortality was observed in any group. Conclusion: This study revealed that propafenone was more effective than amiodarone in maintenance of stable sinus rhythm at the postoperative period in patients who underwent bipolar radiofrequency ablation combined with a mitral valve procedure.

    Bentall Operation in a Patient with Severe Hemophilia A and Marfan Syndrome by Use of a Biologic Composite Graft
    (Elsevier USA, 2016) Yildirim F.; Ozbakkaloglu A.; Ozturk T.; Tetik O.
    We describe a patient with severe hemophilia A and Marfan syndrome who underwent an elective Bentall operation. Because of the severe hemophilia, anticoagulation could not be given postoperatively; thus, a biologic Valsalva conduit graft was used. During the procedure, factor VIII was given as a bolus dose just before incision, then by continous infusion intraoperatively to maintain the factor VIII activity level between 200% and 300%. Minimal postoperative bleeding occurred. The infusion was continued postoperatively at a lower dose until all chest tubes, pacing wires, and invasive catheters were removed. The patient was discharged on postoperative day 7 without adverse events. © 2016 The Society of Thoracic Surgeons.

    Identification and characterization of a novel FBN1 gene variant in an extended family with variable clinical phenotype of Marfan syndrome
    (Taylor and Francis Ltd, 2019) Ergoren M.C.; Turkgenc B.; Teralı K.; Rodoplu O.; Verstraeten A.; Van Laer L.; Mocan G.; Loeys B.; Tetik O.; Temel S.G.
    Marfan syndrome (MFS) is a multi-systemic autosomal dominant condition caused by mutations in the gene (FBN1) coding for fibrillin-1. Mutations have been associated with a wide range of overlapping phenotypes. Here, we report on an extended family presenting with skeletal, ocular and cardiovascular clinical features. The 37-year-old male propositus, who had chest pain, dyspnea and shortness of breath, was first diagnosed based on the revised Ghent criteria and then subjected to molecular genetic analyses. FBN1 sequencing of the proband as well as available affected family members revealed the presence of a novel variant, c.7828G>C (p.Glu2610Gln), which was not present in any of the unaffected family members. In silico analyses demonstrated that the Glu2610 residue is part of the conserved DINE motif found at the beginning of each cbEGF domain of FBN1. The substitution of Glu2610 with Gln decreased fibrillin-1 production accordingly. Despite the fact that this variation appears to be primarily responsible for the etiology of MFS in the present family, our findings suggest that variable clinical expressions of the disease phenotype should be considered critically by the physicians. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.

    Three Cases of Large-Diameter True Brachial and Axillary Artery Aneurysm and a Review of the Literature
    (Elsevier Inc., 2019) Senarslan D.A.; Yildirim F.; Tetik O.
    Aneurysms of the upper extremity mostly originate from trauma, mycotic lesions, thoracic outlet syndrome, previous arteriovenous fistulae, and atherosclerosis. True aneurysms of the brachial and axillary artery are encountered rarely. They can be diagnosed by simple physical examination as a pulsatile mass. However, most of these aneurysms remain asymptomatic until a complication occurs. The primary complication seen with the axillary or brachial artery is embolization. We report 3 large-diameter true brachial artery aneurysms extending to the axillary zone. One of the patients had distal digital emboli causing gangrenous lesions at the finger tips and the other 2 patients had pain and ischemic symptoms in the forearm. All underwent surgical repair. After excision of the aneurysmal segment, arterial continuity was ensured by interposition of a reversed saphenous vein in 2 patients and with a biological vascular graft in 1 patient. Although endovascular techniques are improving, most true brachial artery aneurysms are not anatomically suitable for interventional procedures. Open surgery still preserves its value. © 2018 Elsevier Inc.

    Systemic inflammatory response during cardiopulmonary bypass: Axial flow versus radial flow oxygenators
    (SAGE Publications Ltd, 2022) Yildirim F.; Amanvermez Senarslan D.; Yersel S.; Bayram B.; Taneli F.; Tetik O.
    Background: The objective of this study was to investigate the inflammatory effects of different oxygenator flow pattern types in patients undergoing coronary artery bypass graft surgery with cardiopulmonary bypass. Methods: We designed this randomized, single-blind, prospective study of patients with coronary artery disease. We compared the systemic inflammatory effects of oxygenators with two types of flow: axial flow and radial flow. Therefore, we divided the patients into two groups: 24 patients in the axial group and 28 patients in the radial group. IL-1, IL-6, IL-10, and TNF-α were examined for cytokine activation leading to a systemic inflammatory reaction. The samples were collected at three different time intervals: T1, T2, and T3 (T1 was taken before cardiopulmonary bypass, T2 just 1 h after CPB onset, and T3 was taken 24 h after the surgery). Results: There were no significant differences in demographic characteristics between the two groups. We observed that there were notably lower levels of humoral inflammatory response parameters (IL-1, IL-6, and TNF-α) in the radial flow oxygenator group than in the axial flow group at the specific sampling times. For IL-10, there was no significant difference for any time period. Conclusion: It might be advantageous to use a radial-flow-patterned oxygenator to limit the inflammatory response triggered by the oxygenators in cardiopulmonary bypass. © The Author(s) 2022.

    Efficacy and cost-effectiveness of cell saver usage in the repair of thoracic aortic aneurysms and dissections
    (SAGE Publications Ltd, 2022) Amanvermez Senarslan D.; Yildirim F.; Kurdal A.T.; Damar A.; Ozturk T.; Tetik O.
    Introduction: A substantial amount of blood loss occurs during the open repair of aortic aneurysms or dissections. The aim of the present study is to determine the efficacy and cost-effectiveness of cell saver devices in blood conservation during the open repair of thoracic aortic pathologies. Methods: The present study prospectively collected the data pertaining to 25 patients who underwent surgical management of thoracic aortic aneurysms or dissections using a cell saver (Group 1, n = 25). The volume and cost of transfusion and postoperative outcomes were compared with the second group of patients who underwent surgery without the use of cell savers in the previous year (Group 2, n = 25); the data pertaining to the same were retrospectively collected from the hospital records. The patient characteristics and categorical variables were compared using the x2 test and Fisher’s exact test. Transfusion volume and costs were compared using the independent samples t-test and Mann–Whitney U test. Results: The patients in both the groups displayed similar characteristics and risk factors. The total volume of allogenic red blood cell (p < 0.001) and total blood product (p = 0.01) transfusions were significantly lower in Group 1. The cost of red blood cell (p < 0.001) and total transfusions (p = 0.03) were lower in Group 1. The two groups displayed similar in-hospital morbidity and mortality rates. Conclusions: There was a significant association between the use of cell savers and the decreased need for red blood cell and total blood product transfusions. Considering the cost of the cell saver set, transfusion costs in the two groups were comparable. © The Author(s) 2021.

    Results of endovascular treatments of Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation
    (SAGE Publications Ltd, 2023) Amanvermez Senarslan D.; Yildırım F.; Bayram B.; Kurdal A.T.; Tetik O.
    Objectives: The current study aims to report midterm results of patients treated with endovascular intervention, kissing stent, or covered endovascular reconstruction of the aortic bifurcation, for Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation. Methods: Eighteen patients who have intermittent claudication or chronic limb threatening ischemia with Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease involving the aortic bifurcation enrolled to the study between January 2018 and January 2021. Kissing stents, Advanta V12 (Atrium, Getinge Group), were used in 13 patients, and the covered endovascular reconstruction of the aortic bifurcation technique was used in 4 patients to reconstruct the aortic bifurcation. The patients were followed for a median of 49 months (min. 2, max.58 months). Patency rates, mortality, morbidities, and reinterventions were recorded. Results: The mean age of the patients was 60.4 ± 10 years. Technical success was achieved in 94.4% of the patients, but one patient had to convert to open surgery. Primary patency rate of the remaining patients was 85.6% at 58 months. Target lesion revascularization rate was 11.7%. One patient had successful reintervention for in stent restenosis, and secondary patency rate was 93.3% at 58 months. Limb salvage rate was 84.6% during the follow-up. Two patients had myocardial infarction (11.1%) and one mortality (5.6%) occurred because of cerebrovascular event in the follow-up. Conclusions: Endovascular techniques can be used safely for reconstruction of the aortic bifurcation in Trans-Atlantic Inter-Society Consensus C or D aortoiliac occlusive disease in selected patients who have high risk for open surgery. Covered endovascular reconstruction of the aortic bifurcation is the only technique that showed patency rates approaching open surgery in treatment of aortoiliac occlusive disease involving the aortic bifurcation to date. Although promising patency results were achieved with kissing-covered stents, long-term patency rates were still lower than those achieved with open surgery. Further randomized controlled studies comparing the long-term results of these techniques are needed. © The Author(s) 2023.
