Myocardial protection during elective coronary artery bypasses grafting by pretreatment with omega-3 polyunsaturated fatty acids.

Background/aim: Despite recent advances in coronary artery bypass grafting (CABG), cardioplegic cardiac arrest and cardiopulmonary bypass (CPB) are still associated with myocardial injury. Accordingly, the efforts have been made lately to improve the outcome of CPB by glucose-insulin-potassium, adenosine, Ca(2+)-channel antagonists, L-arginine, N-acetylcysteine, coenzyme Q10, diazoxide, Na+/H+ exchange inhibitors, but with an unequal results. Since omega-3 polyunsatutated fatty acids (PUFAs) have shown remarkable cardioprotection in preclinical researches, the aim of our study was to check their effects in prevention of ischemia reperfusion injury in patients with CPB.

[Superior vena cava syndrome caused by epitheloid hemangioma].

Aim: A case is presented of the surgical treatment of epitheloid hemangioma as a rare cause of superior vena cava syndrome.

Case Report: A 53-year old woman was admitted to the clinic with the symptoms and signs of superior vena cava syndrome. After clinical evaluation and diagnostic tests, she was operated on through median stemotomy, and the desobliteration of the superior vena cava through longitudinal cavotomy was done.
