Natural and modified history of isolated ventricular septal defect: A 17-year study

1992

We studied 882 cases of isolated ventricular septal defect (VSD) diagnosed from 1971 to 1988 with a mean follow-up period of 9.5 years. They represent 22.5% of all congenital heart defects diagnosed in this period. Six hundred eighty-three children (77.4%) did not develop symptoms, had small defects, and the rate of spontaneous closure was high (40.2%). The remaining 199 children presented symptoms; at the initial catheterization 25, 65, 107, and 2 cases were grouped in hemodynamic groups 2, 3, 4, and 5-6, respectively, on the basis of pulmonary flow and resistance. Only seven patients (0.7%) developed aortic regurgitation, and only five patients (0.5%) developed infective endocarditis. Com…

83. Radikalit�tsprinzipien bei der Operation des Coloncarcinoms

1987

Die Prinzipien der radikalchirurgischen Behandlung von Coloncarcinomen umfassen 1. die En-bloc-Resektion von Tumor, regionalem Lymphabflussgebiet und adharenten Organen sowie 2. die Vermeidung einer operationsbedingten Tumorverschleppung. Hierzu dienen verschiedene Verfahren, deren Wert letztlich nicht erwiesen ist, deren Anwendung jedoch das Risiko des Eingriffs nicht erhoht. Voraussetzung fur die Beurteilung des radikalchirurgischen Vorgehens beim Coloncarcinom ist eine standardisierte operative Technik und eine standardisierte pathohistologische Beurteilung.

Maschineller und manueller Bronchusverschlu� ?ergebnisse einer konsekutiven untersuchungsserie

1989

After lobectomy and pneumonectomy in experimental evaluations stapled bronchial closures showed the lowest incidence of inflammatory reaction and the highest strength determined by leakage pressure compared with other suture material. A total of 233 lung resections-performed at Surgical University Clinic Koln-Lindenthal and the Clinic for General and Abdominal Surgery of the Johannes-Gutenberg-Universitat Mainz--were reviewed. Mechanical stapling reduced the rate of bronchopleural fistulas to 2.0% compared with 7.1% after manual suturing. In parallel, mortality related to bronchial stump leakage decreased to 0.7%. Main advantages of bronchial closure with staplers are the simplicity of thei…

Changes of inflammatory mediators in obese patients after laparoscopic cholecystectomy.

2010

Background Obesity is associated with the impairment of immunological functions. The aim of this study was to analyze some inflammatory mediators in obese subjects who underwent laparoscopic cholecystectomy. Methods Seventeen consecutive female patients with a BMI ranging from 35 to 45 kg/m2 (obese) and 17 consecutive female patients with BMI ranging from 20 to 25 kg/m2 (nonobese) were included in the study. All patients were affected by symptomatic gallbladder stone disease and underwent laparoscopic cholecystectomy. Changes in levels of leukocytes, neutrophils, IL-6, IL-10, leptin, and adiponectin were evaluated. Results We observed a significant increase in leukocyte and neutrophil level…

Patency of renal and visceral vessels after open thoracoabdominal aortic replacement.

2015

Objective In thoracoabdominal aortic aneurysms (TAAAs), a paradigm shift is observed from open surgery toward total endovascular aortic repair using fenestrated and branched endografts. Whereas outcome after open replacement in terms of mortality and paraplegia has been evaluated extensively, no studies exist addressing long-term patency of visceral and renal vessels. To enable comparison of target vessel patency between open and endovascular treatment, we analyzed our series of open TAAA replacements. Methods Our vascular surgery database was screened for patients who received open TAAA replacement between 1998 and 2012, and patient records were analyzed retrospectively. All available imag…

German registry for acute aortic dissection type A (GERAADA)--lessons learned from the registry.

2010

A German registry for acute aortic dissection type A (GERAADA) was initiated by the Working Group for Aortic Surgery and Interventional Vascular Surgery of the German Society for Thoracic and Cardiovascular Surgery (GSTCVS) in July 2006. This web-based database was developed to record the data of patients who had undergone surgery for aortic dissection type A. From analyzing the data, we aim to learn how to improve surgical treatment and to identify parameters affecting patient outcome. In the beginning, 33 cardiac centers participated via online access to the registry on the GSTCVS' homepage. Since then, 43 centers in Germany, Switzerland and Austria have begun entering data on the pre- an…

Real-time ultrasonography in the otolaryngology office setting

1993

Over the past two decades, diagnostic ultrasonography has evolved into an extensively used noninvasive imaging modality. It plays a vital role in the disciplines of vascular surgery, cardiology, neonatology, pediatrics, ophthalmology, gynecology, and urology, to name a few, but it is in the field of obstetrics that this technology has been maximally used as an office procedure to evaluate the status of the fetus. In the evaluation of head and neck disorders, ultrasonography has been the subject of sporadic reports for the past 15 years.le3 However, except for the evaluation of thyroid masses,4 it has never been widely accepted in the United States as a diagnostic modality, and has taken a b…

Pure oxygen ventilation during general anaesthesia does not result in increased postoperative respiratory morbidity but decreases surgical site infec…

2014

Background. Pure oxygen ventilation during anaesthesia is debatable, as it may lead to development of atelectasis. Rationale of the study was to demonstrate the harmlessness of ventilation with pure oxygen. Methods. This is a single-centre, one-department observational trial. Prospectively collected routine-data of 76,784 patients undergoing general, gynaecological, orthopaedic, and vascular surgery during 1995–2009 were retrospectively analysed. Postoperative hypoxia, unplanned ICU-admission, surgical site infection (SSI), postoperative nausea and vomiting (PONV), and hospital mortality were continuously recorded. During 1996 the anaesthetic ventilation for all patients was changed from 30…
