    There has been developed a program - analytical system for investigation the structure of the signal in the spectral and time ranges caused by geophysical processes. The main purpose of developing such system is - to investigate the structure of the signal in the spectral and time ranges, caused by geophysical and astrophysical magnetic field of the atmosphere boundary surface layer and to find under - noise periodical processes of geophysical nature. The analysis of the exposing efficiency in the time ranges of the components corresponding to the periods of the moon gravitational tides showed high efficiency of the eigen vectors, chosen according to the criterion MKK which provides very slight probably of the false alarm of omitting displayed signs at the level 10-4

    Late Presentation of Bleeding from a Traumatic Obturator Artery Aneurysm, Successfully Treated by Endovascular Means

    Obturator artery bleeding is rare. During the acute phase of a severe pelvic trauma, massive bleeding can occur immediately. The pelvic fracture often leads to an arterial injury by the broken bone fragments. Our case was unusual due to the absence of any pelvic bone fracture and the late onset of an isolated groin haematoma. The duplex ultrasound and CT scan performed at the admission did not show any acute bleeding but a small groin haematoma. One month later the patient has a major haematoma secondary to an obturator artery pseudo-aneurysm. We successfully performed a selective obturator artery pseudo-aneurysm coil embolization. © 2005 Elsevier Ltd. All rights reserved

    The arterial switch operation in Europe for transposition of the great arteries: a multi-institutional study from the European Congenital Heart Surgeons Association

    OBJECTIVES: This study analyzes the results of the arterial switch operation for transposition of the great arteries in member institutions of the European Congenital Heart Surgeons Association. METHODS: The records of 613 patients who underwent primary arterial switch operations in each of 19 participating institutions in the period from January 1998 through December 2000 were reviewed retrospectively. RESULTS: A ventricular septal defect was present in 186 (30%) patients. Coronary anatomy was type A in 69% of the patients, and aortic arch pathology was present in 20% of patients with ventricular septal defect. Rashkind septostomy was performed in 75% of the patients, and 69% received prostaglandin. There were 37 hospital deaths (operative mortality, 6%), 13 (3%) for patients with an intact ventricular septum and 24 (13%) for those with a ventricular septal defect (P < .001). In 36% delayed sternal closure was performed, 8% required peritoneal dialysis, and 2% required mechanical circulatory support. Median ventilation time was 58 hours, and intensive care and hospital stay were 6 and 14 days, respectively. Although of various preoperative risk factors the presence of a ventricular septal defect, arch pathology, and coronary anomalies were univariate predictors of operative mortality, only the presence of a ventricular septal defect approached statistical significance (P = .06) on multivariable analysis. Of various operative parameters, aortic crossclamp time and delayed sternal closure were also univariate predictors; however, only the latter was an independent statistically significant predictor of death. CONCLUSIONS: Results of the procedure in European centers are compatible with those in the literature. The presence of a ventricular septal defect is the clinically most important preoperative risk factor for operative death, approaching statistical significance on multivariable analysis

    Risk of surgery for congenital heart disease in the adult: A multicentered European study

    BACKGROUND: Surgery for congenital heart disease (CHD) has changed considerably during the last three decades. The results of primary repair have steadily improved, to allow treating almost all patients within the pediatric age; nonetheless an increasing population of adult patients requires surgical treatment. The objective of this study is to present the early surgical results of patients who require surgery for CHD in the adult population within a multicentered European study population. METHODS: Data relative to the hospital course of 2,012 adult patients (age > or = 18 years) who required surgical treatment for CHD from January 1, 1997 through December 31, 2004 were reviewed. Nineteen cardiothoracic centers from 13 European countries contributed to the data collection. RESULTS: Mean age at surgery was 34.4 +/- 14.53 years. Most of the operations were corrective procedures (1,509 patients, 75%), followed by reoperations (464 patients, 23.1%) and palliative procedures (39 patients, 1.9%). Six hundred forty-nine patients (32.2%) required surgical closure of an isolated ostium secundum atrial septal defect. Overall hospital mortality was 2%. Preoperative cyanosis, arrhythmias, and NYHA class III-IV, proved significant risk factors for hospital mortality. Follow-up data were available in 1,342 of 1,972 patients (68%) who were discharged home. Late deaths occurred in 6 patients (0.5%). Overall survival probability was 97% at 60 months, which is higher for corrective procedures (98.2%) if compared with reoperations (94.1%) and palliations (86.1%). CONCLUSIONS: Surgical treatment of CHD in adult patients, in specialized cardiac units, proved quite safe, beneficial, and low-risk
