Mirhosseini, S.K. Forouzannia, S.A.H. Sayegh, M. Sanatkar. Department of Cardiovascular Surgery, Shahid Sadoughi University of Medical Sciences, Yazd, Iran Atrial fibrillation (AF) is the most common arrhythmia after cardiothoracic surgery. AF following coronary artery bypass graft (CABG) is associated with an increase in morbidity, mortality, hemodynamic instability, thromboembolic events, severity of heart failure and ICU and hospital stay. Corticosteroids have a variety of beneficial effects on recovery after elective surgery. This study was designed to test the hypothesis that low dose of Methylprednisolone (MP) can affect post-CABG AF and early complications in patients with severe left ventricle dysfunction who underwent elective off-pump coronary artery bypass. A total of 120 patients with LV dysfunction undergoing elective offpump CABG randomly received either MP or placebo. Diabetic patients and those who were receiving corticosteroids were excluded. The MP group received 5 mg/kg of MP intravenously after induction of anesthesia and the placebo group received an equal volume of normal saline. We evaluated Post-CABG variables including incidence, duration and frequency of AF recurrence and early morbidity such as bleeding, infection, vomiting, renal and respiratory dysfunctions, ICU or hospital stay and early mortality. The mean age of patients was 62.11±12.34 years with the 2.4 male to female ratio. AF occurred in 23 (19.2%) patients. No significant difference in the incidence of new AF was found between the placebo (21.7%) and MP group (16.7%) (P = 0.47). MP did not affect postoperative bleeding, infection, vomiting, renal and respiratory dysfunction and mortality; however, MP significantly reduced ICU and hospital length of stay. MP did not affect the incidence, duration and frequency of AF recurrence in patients with severe LV dysfunction undergoing off-pump CABG. However, MP could reduce ICU and hospital stay significantly in these patients. PP-140 THE ROLE OF ISCHEMIA, ANTIOXIDANT MARKERS AND TYPE 2 DIABETES IN PERIPHERAL ARTERY DISEASE T. Gençpınar1 , R.U.

Emmiler1 . 1 Department of Cardiovascular Surgery, Antalya Research Hospital, Antalya, Turkey; 2 Department of Medical BioChemistry, Antalya Research Hospital, Antalya, Turkey Peripheral arterial disease (PAD) of the lower extremities represents a spectrum of diseases caused by a large number etiology. Atherosclerosis is still being specified. The most common cause of peripheral arterial disease, other diseases can reduce limb perfusion. Congenital, inflammatory, and fibromuscular dysplasia, vasculitis, Buerger’s disease, vascular entrapment neuropathies may affect peripheral circulation. To determine the strategy for the diagnosis and treatment of arterial stenoses, as well as ultrasonographic and hemodynamic evaluation, invasive angiographic studies can carried out. These audits can developed on the basis of low-cost, non-invasiveness, rapid and reliable diagnosis. With an effective multidisciplinary treatment strategy of PAH, improving the natural history (myocardial infarction, stroke, amputation and death) and prevent multiorgan distortion can be possible. Diabetes mellitus is a strong risk factor that contributes to 3–4 times the incidence of PAH. In this study, we plan to investigate the role of new antioxidant markers and ischemia and the role of type 2 diabetes in peripheral arterial disease. In our study, 25 diabetic and 25 non-diabetic patient whom performed peripheral bypass surgery with the diagnosis of peripheral arterial disease were randomized. Following the standard procedure of anesthesia in operations implemented by the same surgical team, followed by standard-dose heparinization, blood samples were collected before and after the cross clamp, and markers of antioxidant paraoxonase, arylesterase, total oxidant capacity and total antioxidant capacity were studied in spectrophotometric method. Antioxidant markers associated with diabetes were compared. In diabetic group ischemia and antioxidant marker increasing was high and we found and correlation between X-clamp time, HbA1c and antioxidant markers.

Department of Cardiovascular Surgery, Kartal Kosuyolu Research Hospital, Turkey Introduction: A secure suture line is the leading factor in the success of the aortic operations. For this purpose, many surgeons prefer to use teflon felt at the anastomosis. In this presentation we share the details of the technique of using teflon felt applied in our clinic. Material and Method: Between January 2007 and June 2012, 587 patients (average age 55.6 years, range 14-92 years) were operated for aortic pathologies. In 273 patients separating ascending aorta graft interposition, 187 patients bentall de bono procedure, 127 patients aortic arch replacement was performed. Of 123 patients were operated on the basis of dissection and 4464 of them were operated on the basis of the aneurysm the distal and proximal aortic greft anastomoses in all patients and coronary button anastomoses, we used teflon felt during the sewing. Discussion: In aortic anastomoses use of teflon felt is the common practice with proven effectiveness. Teflon felt placed in variety of ways. Here, a large proportion of determining is the surgeon’s preference and experience. This study has shown that teflon felt into the sewing line technique is prepared by some surgeons in our clinic and does not require cross stitch through the felt so this is a safe and time saving technique. Results: 12 of the 587 patients (2%) whose avarage drain is 450 cc in the post-op period had revision of bleeding. In long term follow up of the 154 patients no complications were seen resulting from the use of teflon felt.

Chalvatzoulis, C. Graidis, V. Psifos, G. Tsonis, D. Dimitriadis, V. Karasavvidis. Euromedica-Kyanous Stavros Thessaloniki, Greece Introduction: Coronary artery perforation is one of the most serious and important complications of percutaneous coronary intervention (PCI) and is associated with significant morbidity and mortality. Angiographic evidence of perforation has been reported in 0.1% to 3.0% of the lesions treated with various intervention techniques. Case description: A 73-year-old female was admitted to our hospital for coronary angiogram (CAG) because of typical anginal pectoris. There was severe stenosis at the proximal and mid Left Anterior Descending artery (LAD). Ventriculography showed normal left ventricular function and the right coronary artery and left circumflex artery was normal. The decision was made to proceed with an intervention on the LAD. Direct stenting was performed with a 3.0×24 mm stent at an inflation pressure of 12 atmospheres, with an additional 3.5×28 mm stent that was placed proximally overlapping the distal one, at an inflation
