[The Rostock artificial heart--current status and perspectives].

The authors report on their experiences gained by animal experiments (calf) and their attempts (human corpses) concerning adaptation of the apparatus to the human thorax. At the present time they do not see a chance for its routine clinical use. The main reason why is the impossibility to install the extrathoracic driving system into the thoracic cage and last not least the wear of the material used for the heart chambers.

[Contribution to the differential diagnosis of lung infarct, pulmonary tuberculosis and lung neoplasms].

It is reported on the rare case of a symptom-free, atypically localised haemorrhagic pulmonary infarction without provable cause in a 52-year-old male. The patient became conspicuous on account of a plum-sized focal shadow in the right lateral upper field detected during a mass examination. The state was regarded as bronchial. carcinoma. Operation and following histological investigation of the resection preparation finally resulted in the diagnosis.

[Intra-and postoperative complications in pulmonary surgery (author's transl)].

The age of the patients, the causative diseases, and the extent of the surgical operation are decisive for the development of intraoperative and postoperative complications in pulmonary surgery. Restrictive and obstructive pulmonary changes of the older-age group involve the danger of postoperative complications. By our experience the critical age for pulmonary surgery is about 50 years.

[Rare thoracic injuries (biomechanics, diagnosis and therapy) (author's transl)].

Thoracic injuries caused by direct or indirect power action involve various injury effects. The extent of injury depends on the force and the direction of the acting power, on the biomechanical properties of the partial structures of the thorax, and on genetically determined variations of form and structure. These correlations are demonstrated by special examples of rare thoracic injuries. The motto for the diagnostic and the choice of the therapeutical procedure is: "Inter vulnerationem thoracis diagnosis incipiat".

[Valve shunt--construction and hemodynamics].

Certain interventions on the thoracic aorta and its derives require bypass systems. In animal experiments the authors ascertained the proper measurements and tried the behavior of arterial pressure and flow, and the rate of hemolysis during bypass. The experiments have shown that by means of the valve shunt perfusion for several hours is possible.

[Valve shunt for use in heart surgery and surgery on the great vessels].

Surgery with extracorporeal circulation must be carried out within temporary limits because of trauma to the blood by the pumping system and partly because of the oxygenators. For vascular replacement extracorporeal circulation can only conditionally be used because heparinization is required. The authors deviced a bypass for certain surgical interventions on the heart and thoracic aorta without the above mentioned drawbacks, which can be used for a longer period without pump and heparinization. This valve shunt stood all trials in experiment.

[Complications in bilateral large lung cysts (author's transl)].

Complications in bilateral, congenital or acquired large cystic lesions in the lungs are a diagnostic and therapeutic problem. Early diagnosis and treatment is emphasized. When surgical treatment is necessary, decisions about the surgical procedures should be made knowing the in situ condition. Cooperation in decision making between bronchologist and thoracic surgeon is required.

[Myxoma of the heart (author's transl)].

In every valvular defect of the heart and in particular of the mitral valve the existence of a tumour should be taken into consideration if diagnostic criteria are not evident. In this case the operation should not be delayed and performed in extracorporeal circulation.

[Methods and quality of information from myocardial scintigrams in the diagnosis of myocardial infarct].

There is an increasing importance of scintigraphy for the assessment of microcirculation in the myocardium. In animal experiments advantages and disadvantages of negative and positive representation of ischemic myocardiac areas were tried, after experimental infarction in particular. The results by computer scintigraphy prove that positive representation reveals an information on site and extent of an infarction.

[The management of bronchial hemoptysis - case study (author's transl)].

Two case reports exemplify, that in patients with massive hemoptysis occuring in the bronchial system and owing to known or unknown causes, the emergency surgery must not to be delayed. In the case of minor relapsing hemoptysis, especially in old-age patients or borderline operability, the minimum surgical procedure is indicated after diagnosing and finding the localization of the hemorrhage.

[Retrograde perfusion of the coronary sinus].

The investigations by Ratajczak-Pakalska showed peculiarities of cardiac venous circulation which make retrograde perfusion possible. Microcirculation is flowing in two directions, especially in diffuse cardiosclerosis. The results of the authors' animal experiments prove that the method of retrograde perfusion of coronary veins might be used ultimately in these cases.
