Merkel cell carcinoma is a rare and aggressive malignant tumor of the skin. We retrospectively reviewed five patients treated from January 1987 to December 1995. The mean age was 75 years (range, 65-85). There were three primary lesions of the head and neck and two of the extremities. Three were stage II and two were stage III. All primary tumors underwent(More)
THE AIM OF THE STUDY An estimation of influence of different doses of aprotynin on bleeding, coagulation parameters and safety of its use after coronary artery bypass grafting (CABG) in pts without coagulation disorders. MATERIAL AND METHODS 91 patients underwent CABG, 73 men, 18 women in age 37 to 76 +/- 56.5 years. Patients were randomly assigned to 3(More)
Haemolytic anaemia following mitral annuloplasty is uncommon as compared with mitral valve replacement procedures. A 67-year-old woman, who underwent mitral annuloplasty and CABG, developed haemolytic anaemia. Echocardiographic examination revealed mitral regurgitation jet colliding with mitral ring. The management of these cases usually demands redo(More)
A case of a 75-year-old female with a giant left atrial myxoma (54 x 42 mm in transthoracic echocardiography) is presented. She remained in a stable condition, however, developed a low cardiac output syndrome shortly after echocardiographic examination. This was caused by tumour displacement from the atrial wall into the left ventricle. The patient(More)
The case of a 66-year-old male with acute myocardial infarction (AMI) complicated by cardiogenic shock is presented. Because of failed primary PCI, after stabilisation of ischaemia and haemodynamics by medication and IABP he was transferred to a distantly located cardiosurgery unit. This patient underwent successful emergency CABG on the second day after(More)
The aim of this study was to evaluate the influence of pressure applied while assessing the graft's tightness on the expression of adhesion molecules. Another goal was to find a correlation between the type of fluid (heparynized blood or saline) used during preparation of the conduit and the expression of the adhesion molecules. Saphenous vein fragments(More)
BACKGROUND Differences between men and women in the prevalence and clinical course of coronary artery disease (CAD) have been well documented. There are no data in literature on the differences between males and females in the incidence of post-infarction left ventricular (LV) wall motion abnormalities of akinesia/dyskinesia type and the outcome after(More)
UNLABELLED Coronary Artery Bypass Grafting (CABG) is widely accepted as an effective and durable method of treatment of Coronary Artery Disease. In some patients however, recurrent angina and the necessity of reoperation (RE-CABG) occurs. AIM The aim of the study is the estimation of the results of RE-CABG in own material. MATERIAL AND METHODS In years(More)
A case of 47-year-old man with occlusion of the subclavian artery occurring few months after CABG with the left internal mammary artery grafting is presented. The patient developed a subclavian-coronary steal syndrome with retrograde blood flow from the coronary circulation to the subclavian artery through the left internal mammary artery. Clinical(More)
