Klappenerhaltende Resektion eines Fibroelastoms
2002
Papillare Fibroelastome sind seltene und gutartige Tumore des Herzens mit bevorzugter Lokalisation im Bereich der Klappen, die mit schwersten Komplikationen oder fatalen und malignem Verlaufen einhergehen konnen. In diesem Fallbericht wird uber eine modifizierte, klappenerhaltende Operationstechnik eines symptomatischen Fibroelastoms an der Aortenklappen berichtet.
Molar masses and structure in solution of haemoglobin hyperpolymers--a common calibration of size exclusion chromatography of these artificial oxygen…
1997
We are developing artificial oxygen carriers for medical use, based on synthetic polymers--so-called hyperpolymers--obtained by cross-linking mammalian haemoglobins. One requirement with respect to the polymers is that they should not increase the oncotic pressure of blood remarkably--this can be realized by high molecular weights of the polymers with a narrow distribution. They may act as a oxygen transporting blood additive, and--in combination with a plasma expander--as a blood substitute. Another important and desired property of the artificial oxygen carrier is a low viscosity, which--first--is due to a high degree of uniformity of the polymer size (or molar mass) distribution and--sec…
Chronisch thromboembolische pulmonale Hypertonie: Empfehlungen der Kölner Konsensus Konferenz 2016
2016
The 2015 European Guidelines on Pulmonary Hypertension did not cover only pulmonary arterial hypertension (PAH), but also other significant subgroups of pulmonary hypertension (PH). In June 2016, a Consensus Conference organized by the PH working groups of the German Society of Cardiology (DGK), the German Society of Respiratory Medicine (DGP) and the German Society of Pediatric Cardiology (DGPK) was held in Cologne, Germany to discuss open and controversial issues surrounding the practical implementation of the European Guidelines. Several working groups were initiated, one of which was dedicated to the diagnosis and treatment of chronic thromboembolic pulmonary hypertension (CTEPH). In ev…
Long-term results after thromboendarterectomy for chronic pulmonary embolism1
1999
Objective: In patients with chronic thromboembolic pulmonary hypertension, pulmonary vascular resistance (PVR) can be reduced by pulmonary thromboendarterectomy (PTE). In this study, long-term symptomatic and hemodynamic effects were investigated. Methods: Twenty-two patients (12 female, 10 male, mean age 40 years, preoperative NYHA functional class II/III/IV: n = 1/12/9) were re-evaluated 48‐72 months (mean 60 months) after surgery. In addition to clinical assessment, radiologic, hemodynamic and echocardiographic investigations were performed. Results: All patients reported a marked improvement of their clinical condition. At follow-up, 11 patients were identified as NYHA class I, 10 as NY…
Surgical treatment of chronic thromboembolic pulmonary hypertension
1999
Background: Chronic thromboembolic pulmonary artery obstruction from unresolved pulmonary emboli is characterized by persistent elevation of pulmonary vascular resistance and progressive right heart dysfunction and failure. The diagnosis of chronic thromboembolic pulmonary hypertension is difficult and often missed. Medical therapy is ineffective in these patients. The prognosis is poor and depends on the degree of pulmonary hypertension. Pulmonary thromboendarterectomy has proven to be an effective and potentially curative surgical therapy for this clinical entity although less than 1000 cases have been reported in the surgical literature. Methods: The current principles of diagnosis, pati…
Anti-inflammatory properties of simvastatin on leukocyte-endothelial cell interactions following hemorrhagic shock
2002
Background Hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) have been shown to lower serum cholesterol levels. Recent studies reported that statins have vasculoprotective effects independent of their cholesterol-lowering properties. We studied simvastatin for its ability to modulate leukocyte-endothelial cell interactions under acute inflammation following hemorrhage and reperfusion. Methods The effects of simvastatin on leukocyte-endothelial cell interactions were observed by intravital microscopy in the rat mesenteric microcirculation and by immunohistochemical analyzes. Simvastatin (50 μg/kg or 100 μg/kg) was administrated intraperitoneally 18 h before study. Inf…
