In a considerable number of cases, blunt chest trauma also involves cardiac lesions including myocardial contusion or disruption pericardial effusion, or valve rupture. Definite cardiac trauma poses a challenge to everyone involved in intensive care, as early diagnosis and prompt treatment may be necessary to prevent a fatal outcome. We report a 32-year-old(More)
Objective parameters are needed to quantify cerebral dysfunction following cardiac surgery in outcome and comparative studies. In this investigation we assessed the value of the late auditory evoked potentials N100 and P300 to measure the neuropsychological deficit after coronary artery bypass grafting (CABG). N100, an exogenous potential is influenced by(More)
BACKGROUND In the present study the influence of different storage solutions on endothelial integrity or damage was investigated with direct methods particularly with transmission electron microscopy (TEM), scanning electron microscopy (SEM) and immunohistochemistry. METHODS Saphenous vein segments of 10 cm in length were taken surgically from 6 male(More)
Pulmonary sequestration is a rare anomaly. An accurate pre-operative evaluation of its vascular supply is essential for the surgeon's operative approach. We describe here an intrapulmonary sequestration with vascular arterial supply via the left circumflex and the right coronary artery. This case demonstrates that if aortography is unrevealing, then a(More)
To find out whether indirect negative inotropic effects of carbachol (i.e. decreases in force of contraction that had been stimulated by cyclic AMP-increasing agents) might differ dependent on the agonist employed to increase contractile force in isolated human right atrium, we studied effects of carbachol on atria prestimulated with noradrenaline,(More)
Nocardial sepsis occurred after aortic valve replacement in two patients. A septic suture aneurysm of the aortotomy was resected and the prosthesis exchanged in one of them. The other received conservative treatment for sternal osteomyelitis and local mediastinitis. Clinical cure was followed by relapse and death from cerebral infarction, and necropsy(More)
In spontaneously hypertensive rats (SHR), in normotensive related controls (WKY), as well as in non-related controls (NR), the rarefaction of the capillary bed in the gracilis muscle has been studied. By comparing four different in vivo and in vitro techniques for estimation of the number of capillaries, a rarefaction of about 30% in SHR, was found. The(More)
From 1979 through 1988, 215 patients with pulmonary metastases were treated in our department. Surgery was possible in 112 patients. Eighty-two patients were resected curatively, whereas 30 had only palliative surgery. The operation mortality was 1.8%. The essential prognostic factors were the complete removal of all pulmonary metastases, the portal or(More)
A total of 407 patients were hospitalized on account of a peripheral round lesion in the lungs (PR); 176 of these patients were inoperable for a wide range of different reasons. In 32.9% of the cases, a peripheral bronchial carcinoma presented, in 26.9%, the lesions were metastases, and in 2% malignant growths that were not further classified. All the(More)
