Öğe Axillary Artery Injury Following Inferior Dislocation of the Glenohumeral Joint(Derman Medical Publ, 2013) Korkmaz, Mehmet Fatih; Disli, Olcay Murat; Karakaplan, Mustafa; Akca, Baris; Erdem, Mehmet NuriIn this paper, we described a case of axillary artery injury following a primary traumatic inferior shoulder dislocation. It is aimed at raising the index of awareness for identifying this limb threatening injury based on its pathognomonic triad of findings during clinical examination, and to consolidate current thinking on its subsequent management and outcome. To our knowledge, this is the only report in the English literature describing vascular injury in primary traumatic inferior shoulder dislocation in a young man.Öğe A case with pyopericardium and cardiac tamponade induced by migration of ventriculoperitoneal shunt catheter(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2014) Karakurt, Cemsit; Celik, Serkan Fazli; Ozturk, Mehmet; Disli, Olcay Murat; Yakinci, CengizVentriculoperitoneal (VP) shunt is a method used in the treatment of hydrocephalus. In this article, we report a four-year-old girl who was implanted a VP shunt due to hydrocephalus, and referred to our clinic due to dyspnea and cardiomegalia. Echocardiographic examination revealed cardiac tamponade and pericardial effusion. Thorax computed tomography, which was performed due to suspicion of migration of the VP catheter to the pericardium, showed that the VP catheter tip was inside the pericardium. Pericardiectomy was performed due to pericardial constriction was developed after tube drainage, and the VP shunt catheter was shortened and replaced into the abdominal cavity.Öğe Coronary Bypass Surgery in Patients with Pulmonary Hypertension: Assessment of Early and Long Term Results(Medical Tribune Inc, 2015) Akca, Baris; Erdil, Nevzat; Disli, Olcay Murat; Donmez, Koksal; Erdil, Feray; Colak, Mehmet Cengiz; Battaloglu, BektasPurpose: We aimed to evaluate the effects of preoperative pulmonary hypertension (PH) on early and long term results in patients undergoing coronary bypass surgery and the effects of coronary bypass surgery on PH. Methods: Among 2325 patients who underwent elective isolated coronary artery bypass surgery between March 2003 and March 2012, 287 patients with high preoperative pulmonary arterial pressure (PAP) >= 30 mmHg were examined. Patients' data were obtained by retrospective examination of our clinic's database. 69 patients who had complete parameters included in the study. Results: There was no increase in the New York Heart Association (NYHA) functional classification 84% of cases. Preoperative and postoperative values of the mean ejection fraction and mean PAP of patients was respectively 45.28 +/- 9.67 (25-65), 46.03 +/- 12.4 (20-65) (p = 0.447), 36.67 +/- 6.81 (30-60) mmHg, 37.81 +/- 10.07 (20-70) mmHg (p = 0.378). The late mortality of cases was 5.79%. In our study, during 33.9 +/- 17 (9-100) months follow up period, life expectancy was calculated as 94.7 months. Conclusion: Preoperative evaluation of these patients for appropriate medical treatment at peroperative and postoperative period, coronary bypass can be performed with low morbidity and mortality rates. In the late period after surgical revascularization PH showed no significant change and had no adverse effect on quality of life.Öğe The effects of pulmonary hypertension on early outcomes in patients undergoing coronary artery bypass surgery(Tubitak Scientific & Technological Research Council Turkey, 2016) Akca, Baris; Donmez, Koksal; Disli, Olcay Murat; Akgul Erdil, Feray; Colak, Mehmet Cengiz; Aydemir, Ilhan Koray; Battaloglu, BektasBackground/aim: To investigate the effects of pulmonary hypertension on early clinical variables in patients undergoing coronary artery bypass grafting surgery. Materials and methods: The preoperative echocardiographic data of patients who underwent isolated coronary artery bypass surgery were evaluated retrospectively. A total of 1244 patients were included in the study. The patients were divided into two groups: one group consisted of patients with systolic pulmonary artery pressure (SPAP) values equal to or greater than 30 mmHg (Group 1, n = 184), while the other group consisted of patients with SPAP values below 30 mmHg (Group 2, n = 1060). Results: Early mortality was similar in both groups (0% in Group 1 and 1.2% in Group 2; P > 0.05). Comparison of postoperative data indicated that Group 1 had a higher need for inotropic agent treatment, a longer average duration of ventilation, and a longer average duration of stay in the intensive care unit (P < 0.05). For the other variables, no significant differences were identified between patients with and without pulmonary hypertension (P > 0.05). Conclusion: Mild pulmonary hypertension (mean SPAP = 37.7 +/- 8.4 mmHg) was not associated with a significant difference in the mortality of patients undergoing coronary artery bypass grafting. For patients undergoing this type of coronary bypass surgery, lower morbidity and mortality rates can be achieved through comprehensive preoperative examinations and effective perioperative medical procedures.Öğe Effects of rivaroxaban on myocardial ischemia-reperfusion injury in rats(2022) Kahraman, Ercan; Akça, Barış; Çolak, Mehmet Cengiz; Disli, Olcay Murat; Parlakpınar, Hakan; Battaloglu, Bektas; Erdil, NevzatMyocardial infarction and further ischemia-reperfusion injury is a life-threatening conditions in humans. In this study, the effects of rivaroxaban, an anticoagulant agent, were aimed to be studied in a myocardial ischemia-reperfusion (I/R) injury model in rats. Male Wistar-albino rats were allocated into three groups; Rivaroxaban (n=15), control (n=15) and sham (n=10). Myocardial ischemia (30 minutes) and then reperfusion (120 minutes) were surgically performed in the rivaroxaban given (3mg/kg/ day by gavage for 10 days before surgical procedures) and the control groups. Electrocardiography changes, blood pressure and heart rate were recorded before ischemia, and during the periods of ischemia and the reperfusion. Hemodynamic and blood parameters were recorded. Necrotic tissue in the myocardium was determined by the triphenyl tetrazolium chloride dye method. The extent of myocardial necrosis and risk area was calculated using a computer-assisted image program. In the rivaroxaban administered group, the size of necrotic area in the myocardium decreased significantly, however, mean heart rate and mean arterial blood pressure did not change. K+ and CK levels in serum, which are indicative of tissue necrosis, were significantly lower in the rivaroxaban group compared to the control group (p<0.05). Rivaroxaban use, compared to the control group, effectively reduced the extent of myocardial injury as assessed by less necrotic myocardial tissue in rats. This protective effect of rivaroxaban may be attributed to its less thrombus formation in the coronary arteries during ischemia and less acidosis during tissue damage.Öğe Extracorporeal Membrane Oxygenation After Living-Related Liver Transplant(Baskent Univ, 2015) Gedik, Ender; Celik, Muhammet Reha; Otan, Emrah; Disli, Olcay Murat; Erdil, Nevzat; Bayindir, Yasar; Kutlu, RamazanVarious types of extracorporeal membrane oxygenation methods have been used in liver transplant operations. The main indications are portopulmonary or hepatopulmonary syndromes and other cardiorespiratory failure syndromes that are refractory to conventional therapy. There is little literature available about extracorporeal membrane oxygenation, especially after liver transplant. We describe our experience with 2 patients who had living-related liver transplant. A 69-year-old woman had refractory aspergillosis pneumonia and underwent pumpless extracorporeal lung assist therapy 4 weeks after liver transplant. An 8-month-old boy with biliary atresia underwent urgent liver transplant; he received venoarterial extracorporeal membrane oxygenation therapy on postoperative day 1. Despite our unsuccessful experience with 2 patients, extracorporeal membrane oxygenation and pumpless extracorporeal lung assist therapy for liver transplant patients may improve prognosis in selected cases.Öğe Is There Any Difference in Risk Factors between Male and Female Patients in New-Onset Atrial Fibrillation after Coronary Artery Bypass Grafting?(Georg Thieme Verlag Kg, 2018) Akca, Baris; Erdil, Nevzat; Colak, Mehmet Cengiz; Disli, Olcay Murat; Battaloglu, Bektas; Colak, CemilBackground We aimed to investigate the risk factors of post-coronary artery bypass grafting (CABG) atrial fibrillation (AF) in male and female patients without any history of AF, to identify the sex-specific risk factors, and to examine the effect of sex-specific risk factors on the overall population. Methods This retrospective study was conducted using the hospital database with 4,758 patients who underwent CABG surgery. Among them, 2,836 patients with complete data participated in this study. The female patients were divided into two groups as patients who developed new-onset AF after CABG and those who did not. The relationship between the patients' variables and risk factors of post-CABG AF was examined. Results The overall incidence of post CABG AF was 12.9% (386/2,836). Sex-specific incidence of AF was similar: 3.2% (91/690) and 12.9% (277/2146) in female and male patients, respectively (p = 0.849). Multiple analysis revealed the independent risk factors for male and female patients, respectively: mean age (odds ratio [OR] = 1.057, OR = 1,076), age over 65 years (OR = 2.156, OR = 2.736), the European System For Cardiac Operative Risk Evaluation Scores (EuroSCORE) (OR = 1.13, OR = 1.218), COPD (OR = 1.589, OR = 1.789), BUN level (OR = 1.026, OR = 1.019), mean cardiopulmonary bypass (CPB) time (OR = 1.007, OR = 1.010), prolonged CPB time (OR = 1.604, OR = 2.309), mean cross-clamp time (OR = 1.009, OR = 1.017), need of inotropic support (OR = 2.249, OR = 2.731), and mean mechanical ventilation time (VT) (OR = 1.026, OR = 1.027). Low left ventricular ejection fraction (LVEF) (OR = 1.419), left ventricular (LV) aneurysm repair (OR = 1.533), carotid artery disease (OR = 1.750), prolonged VT (OR = 1.729), and use of intra-aortic balloon pump (IABP) (OR = 2.436) were found to be the risk factors only for male AF patients. Unstable angina (OR = 1.969), right coronary artery (RCA) disease (OR = 2), prolonged cross-clamp time (OR = 2.152), and the number of grafts per operation (OR = 1.298) were found to be the risk factors only for female AF patients. Conclusion This study suggests that predictors of AF in the overall population may be due to isolated patient groups. Multiple regression analysis and artificial intelligence modelling should be performed on large-scale, isolated groups to make strong AF prediction.Öğe Is there any difference in risk factors between male and female patients in new-onset atrialfibrillation after coronary artery bypass grafting?(Georg thıeme verlag kg, rudıgerstr 14, d-70469 stuttgart, germany, 2018) Akca, Baris; Erdil, Nevzat; Colak, Mehmet Cengiz; Disli, Olcay Murat; Battaloglu, Bektas; Colak, CemilBackground We aimed to investigate the risk factors of post-coronary artery bypass grafting (CABG) atrial fibrillation (AF) in male and female patients without any history of AF, to identify the sex-specific risk factors, and to examine the effect of sex-specific risk factors on the overall population.

Right atrial thrombus formations after primary suture repairs of the ASD and evidences of thromboembolic complications are extremely rare. Specifically, the cases of thromboembolic complications have high mortality and morbidity risks. Two cases of giant intra-atrial thrombus formation detected in the late stage after primary repairs of ASDs are being discussed.Öğe The Molecular Mechanism of the Effect of Carvacrol on Desflurane Inhalation-Induced Liver Damage in Rats(Colegio Farmaceuticos Provincia De Buenos Aires, 2022) Disli, Zeliha Korkmaz; Delen, Leman Acun; Tas, Hakan Gokalp; Kuyrukluyildiz, Ufuk; Disli, Olcay Murat; Yazici, Gulce Naz; Coban, AbdulkadirThe metabolite of desflurane has been linked to hepatotoxicity. Carvacrol possesses antioxidant, antibacterial, antifungal, anticancer, anti-inflammatory, and spasmolytic properties, according to research. Our goal is to demonstrate that carvacrol protects rats' livers against repeated doses of desflurane. Healthy (HG), desflurane (DS), and carvacrol + desflurane treatment (CDS) groups were formed from 18 albino male Wistar rats. A single dosage of carvacrol and 6% desflurane was given for 2 h on the 0th and 8th days. In the CDS group, the ALT and AST, MDA, TOS, NF-xB, TNF-alpha IL1 beta levels were lower compared to the DS group (p < 0.001). The tGSH,TAS levels were found to be higher in the CDS group compared to the DS group (p < 0.001). It was determined that the mean degeneration level, Kupffer cell activation and PMNL infiltration were found to be lower compared to the DS group (p < 0.05).We confirmed that carvacol can be used in the treatment of desflurane-related liver injury.Öğe Nebivolol in preventing atrial fibrillation following coronary surgery in patients over 60 years of age(Soc Brasil Cirurgia Cardiovasc, 2014) Erdil, Nevzat; Kaynak, Murat; Donmez, Koksal; Disli, Olcay Murat; Battaloglu, BektasObjective: Postoperative atrial fibrillation is a common complication after cardiac surgery, with an incidence as high as 20-50%. Increased age is associated with a significant increase in postoperative atrial fibrillation risk. This common complication is associated with higher morbidity and mortality rates. The aim of this study was to assess the efficacy of nebivolol in preventing atrial fibrillation following coronary artery bypass surgery in patients over 60 years of age. Methods: In this prospective randomized study, 200 patients who were candidates for elective coronary artery bypass surgery were divided into two groups. The first group was administered with nebivolol and the second group was administered with metoprolol. Treatment was initiated four days prior to surgery, and patients were monitored for atrial fibrillation until discharge. Forty-one patients recieved 50 mg metoprolol succinate daily, which was initiated minimum 4 days before surgery. Results: Demographic data were similar in both groups. The incidence of postoperative atrial fibrillation in both groups was similar, with no significant difference being identified [n=20 (20%); n=18 (18%), P=0.718; respectively]. There were not any mortality at both groups during study. Inotropic agent requirement at ICU was similar for both groups [n=12 (12%), n=18 (18%), P=0.32]. Conclusion: We compared the effectiveness of nebivolol and metoprolol in decreasing the incidence of postoperative atrial fibrillation, and determined that nebivolol was as effective as metoprolol in preventing postoperative atrial fibrillation at patients. Nebivolol may be the drug of choice due to its effects, especially after elective coronary artery bypass surgery.Öğe Perioperative Management of a Levoatrial Cardinal Vein in the Absence of the Brachiocephalic Vein(Texas Heart Inst, 2013) Disli, Olcay Murat; Battaloglu, Bektas; Erdil, Nevzat; Karakurt, Cemsit; Elkiran, OzlemLevoatrial cardinal vein is a rare congenital anomaly of the systemic veins. It is commonly associated with left-sided obstructive conditions such as aortic atresia, mitral atresia, and cor triatriatum. We report the case of a 14-year-old boy who was undergoing surgery for correction of a secundum atrial septal defect. Intraoperatively, we discovered that he had a levoatrial cardinal vein and no brachiocephalic vein. However, collateral vessels provided adequate flow to the right atrium, and the patient's left-sided venous pressure was not excessive, so we ligated the levoatrial cardinal vein and directly repaired the septal defect. Postoperatively, the left venous drainage was satisfactory and the patient was asymptomatic. In addition to our patient's case, we discuss the embryology, diagnosis, and treatment of levoatrial cardinal vein.

In this study, we investigated the toxic effects of TCDD and the preventive effects of protocatechuic acid (PCA), a widespread phenolic compound, in the heart tissue of rats. For this purpose, 3-4 months old 28 rats with 280-310g body weights were equally divided into 4 groups (control, TCDD, PCA, TCDD+PCA group). A 2g/kg dose of 2,3,7,8-TCDD and 100mg/kg dose of PCA were dissolved in corn oil and given orally to the rats for 45 days. The results indicated that TCDD induced oxidative stress by increasing the level of thiobarbituric acid reactive substance and by decreasing the levels of glutathione, catalase, glutathione peroxidase and superoxide dismutase in the heart tissue of rats. In contrast, PCA treatment prevents the toxic effects of TCDD on oxidative stress. In addition, histopathological alterations such as necrosis and hemorrhage occurred in TCDD group, and PCA treatment partially prevents these alterations in heart tissue. In this study, it was concluded that TCDD exposure led to toxic effects in heart tissue and PCA treatment could prevent the toxicity of TCDD.Öğe A Rare Congenital Anomaly: Surgery of Combined Discrete Subaortic Membrane Complicated by the Absence of the Superior Vena Cava(İnönü Üniversitesi Tıp Fakültesi Dergisi, 2014) Isık, Onur; Disli, Olcay Murat; Bas, Tolga; Kutsal, AliPersistent left superior vena cava accompanied by an absent right superior vena cava in visceroatrial situs solitus is an extremely rare congenital anomaly. Although absence of RSVC alone in patients with visceroatrial situs solitus is of no hemodynamic significance, its diagnosis before surgery or other invasive procedure is important to avoid various management difficulties, which include complications such as the implantation of a transvenous pacemaker or defibrillator, placement of pulmonary artery catheter for intraoperative or intensive care unit monitoring, systemic venous cannulation for cardiopulmonary bypass or extracorporeal circulation, cavopulmonary anastomosis, and orthtopic heart transplantation. We present a case with the absence of RSVC along with PLSVC in association with a discrete subaortic membrane, at the end of which the patient was operated successfully.Öğe Rosuvastatin pretreatment does not attenuate microalbuminuria after coronary artery bypass grafting(Baycinar Medical Publ-Baycinar Tibbi Yayincilik, 2014) Secici, Serkan; Battaloglu, Bektas; Uyar, Ihsan Sami; Akpinar, Mehmet Besir; Abacilar, Ahmet Feyzi; Disli, Olcay Murat; Erdil, NevzatBackground: This study aims to evaluate whether rosuvastatin attenuates microalbuminuria following coronary artery bypass grafting (CABG) with a cardiopulmonary bypass (CPB). Methods: This prospective study was performed in 40 patients (37 males, 3 females; mean age 59.0 +/- 10.1 years; range 48 to 78 years) who were scheduled for isolated CABG. The patients were divided into two groups including control group (n=20) and rosuvastatin group (n=20) which received rosuvastatin 20 mg/day seven day (20 mg/day) before elective CABG. Microalbuminuria was measured after the insertion of the urinary catheter, before CPB, after the termination of CPB, and at the sixth and 24th hours in the intensive care unit using a spot urine sample. Serum C-reactive protein was measured before the induction of anesthesia and at the sixth and 24th hours in the intensive care unit using blood samples. Results: The demographic data and preoperative characteristics of the patients were similar. There were no significant differences in the CPB, cross-clamp and surgery time, inotropic support, extubation times, and time to discharge from hospital between the two groups. The urinary albumin/creatinine ratio increased in both groups, compared to the baseline measurement and reached a maximum level at the end of CPB (p<0.05). Albumin/creatinine ratio measured at the sixth hour in the intensive care unit was significantly higher in the rosuvastatin group (0.69 vs. 2.10, p=0.002). Serum C-reactive protein increased at 24 hour postoperatively in both groups. Conclusion: Rosuvastatin pretreatment does not attenuate microalbuminuria and the inflammatory response after CABG surgery.Öğe An Unexpected Cause of Respiratory Distress and Cyanosis: Cardiac Inflammatory Myofibroblastic Tumor(Wiley-Blackwell, 2013) Elkiran, Ozlem; Karakurt, Cemsit; Erdil, Nevzat; Disli, Olcay Murat; Dagli, Adile FerdaInflammatory myofibroblastic tumor is an uncommon spindle cell tumor, occurring mainly in children and young adults. It is an extremely rare cardiac tumor especially patients under 1 year. Although it is benign, the tumor may be very aggressive locally. The diagnosis of this unusual pediatric cardiac tumor without pathologic specimens is difficult. We report a rare case of inflammatory myofibroblastic tumors of the right ventricle in a 7-month-old girl presenting with respiratory distress and cyanosis.Öğe Use of autologous pericardium for mitral leaflet reconstruction in a child with endocarditis(Soc Brasil Cirurgia Cardiovasc, 2013) Disli, Olcay Murat; Karakurt, Cemsit; Erdil, Nevzat; Battaloglu, BektasWe present a case of successful repair of the mitral valve for active infective endocarditis. Mitral valve repair was performed through debridement of vegetation and abscess, resection and repair of the posterior mitral leaflet and posterior repair with autologous pericardium. Postoperative period was uneventfully, with no evidence of recurrent infection, and echocardiogram showed mitral valve competence with mild mitral regurgitation. We demonstrate that valve repair is a feasible choice in cases of active endocarditis in children.
