[Radiological lung changes in progressive pulmonary insufficiency (author's transl)].

Chest radiographs can reflect increasing pulmonary insufficiency of shock lung. In the early and intermediate stages, there is almost pure interstitial oedema which, in the later stages becomes alveolar-interstitial. In addition one may find evidence of broncho-pneumonia. Respiratory insufficiency is due to abnormalities of perfusion and distribution and is aggravated by disturbance of oxygen diffusion. The latter is due to an increase in the alveolo-capillary diffusion distance in the presence of interstitial oedema. It was not possible to demonstrate quantitatively significant precapillary shunts greater than 25 mu.

[A review of the findings on chest examinations and at autopsy in surgical patients under intensive care (author's transl)].

The present paper deals with the findings on examination of the chest and at autopsy in 100 selected surgical patients under intensive care; of these 17% were post-traumatic, 55% had post-operative lung complications and in 28% there had been no trauma or previous operations. The accuracy of the radiological diagnosis was checked against the autopsy findings. Pneumonia and pulmonary oedema were the most common lung complications in all three groups, with an incidence of 59 to 82%, and were diagnosed with an accuracy of 92 to 95%. Other conditions which were looked for were pulmonary congestion, emboli and lung infarcts, pleural effusions, atelectasis, pulmonary haemorrhage or contusion and pneumothorax. The most common mis-diagnosis was in the demonstration of emboli and infarcts, where accuracy was only 64%. The difficulties in differential diagnosis of the radiological appearances due to these pulmonary complications are discussed.

[The Bland-White-Garland syndrome: hemodynamics, clinical picture, therapy].

Two patients with anomalous origin of the left coronary artery from the pulmonary artery are presented. Anatomy, embryology, the problem of the direction of blood flow in the anomalous vessel, and the clinical symptoms of this syndrome are discussed. In spite of large fibrotic areas in the myocardium, the ECG-changes were minimal. Therefore, a nearly normal ECG does not exclude this anomaly. In patients with sudden, unexpected death one should suspect an anomalous origin of a coronary artery. The classification in an "infantile" and "adult" type reflects the extent to which collateral vessels have developed. Ligation of the anomalous coronary artery at the side of its origin with concomitant aorto-coronary bypass appears to be a rational and the only effective way of therapy.
