[Value of cineradiography in the study of Budd-Chiari syndrome. Value of various angiographic technics. Apropos of 8 cases].

Eight cases of surgically proven Budd Chiari disease, have been explored pre- operatively by cine-angiography. This procedure is very safe and simple, and allows a dynamic study of the intra- and extra-hepatic pathways. The authors are reviewing the different modalities of radiologic evaluation of Budd-Chiari disease, including inferior vena cava phlebography, opacification of supra-hepatics veins, and coeliac arteriography. They propose a flow sheet in the radiological work-up of these patients.

[Radiological diagrams of the various anatomical forms of mitral incompetency. Report on twenty-nine cases (author's transl)].

The authors compared the radiological findings in 29 cases with the operative or autopsy findings and discuss the criteria at present adopted during standard radiological examination and hemodynamic and angiographic exploration of mitral incompetency to determine the anatomical type. From the radiological findings, one may characterize acute mitral incompetency with a small heart and pulmonary vascular changes from chronic mitral incompetency, the diagnostic criteria of valvular prolapse, ruptures of the chordae tendineae and poor function of the papillary muscles. The authors give a synthesis of their results compared with those in the literature.

Post-traumatic-shock lung: postmortem microangiographic and pathologic correlation.

In post-traumatic-shock lung, increased pulmonary vascular resistance and pulmonary hypertension are prominent features. The explanation for them was sought by postmortem microangiography of the lungs of 17 patients dying of respiratory failure after trauma. The 10 patients with thoracic injury died earlier (1-8 days). Extravasation of contrast material due to alveolar capillary rupture was present in all but one specimen and occupied 20% of the sampled area. Pulmonary artery thrombi lay proximal to these extravasations. Hypovascular areas due to infection and hemorrhagic alveolitis were found in all patients and involved 40% of the surface area. The small pulmonary arteries were poorly filled and contained many microthrombi. Some patients had hematomas, cavities, and areas of interstitial edema occupying about 5% of the lung area and associated with compressed or occluded vessels. Several mechanisms including pulmonary trauma may be responsible for the antemortem rupture and obstruction of small blood vessels. In the post-traumatic-shock lung, small artery occlusion and compression are associated with pulmonary hemorrhage, infarction, and infection and are important contributors to perfusion abnormalities and respiratory failure.

[Broncholithiasis].

Eight cases of broncholithiasis requiring surgical treatment are reported, and diagnostic and therapeutic difficulties of this affection discussed. Clinical symptomatology is not very specific and associates slight or moderate hemoptyses with signs of a febrile pulmonary disorder. Expectoration of a broncholith was not observed in these cases. Radiological images were suggestive by demonstrating hilar and/or peripheral calcifications, often with a parenchymatous opacity in the same region. Fibroscopy is not always conclusive and may even suggest the presence of a tumor. A tuberculous etiology is admitted in France in spite of the absence of bacilli in the sputum. Differential diagnosis from cancer is a real problem, this explaining why two pneumonectomies were performed, in addition to the six lobectomies.

[Pulmonary xanthogranulomas (author's transl)].

The authors report on six cases of pulmonary xanthogranuloma. They stress the latent character of these dense, round isolated parenchymatous tumors. The tumors have an homogeneous aspect without calcifications and regional adenopathies. The radio-clinical diagnosis is difficult to assess because the para-clinical examinations are regularly negative. The differential diagnosis is made either clinically, especially with hamartochondroma and peripheral cancer, or histologically according to the predominance of various types of cells, especially with a solitary plasmocytoma, a lymphoma or a sclerosant hemangioma. Histology is the only key to diagnosis. For these reasons, the decision for surgical intervention presents a problem as the patients, often young, present no visible signs and the lesions evolve but very slowly.

[Mediastinal bronchogenic cysts in adults. Cardiovascular symptomatology (author's transl)].

The authors describe seven patients operated upon for mediastinal bronchogenic cysts and emphasize the problems of differential diagnosis from cardiac and vascular affections: enlarged left auricle and aneurysm of the thoracic aorta. They review the published literature on atypical bronchogenic cysts with cardiac or vascular symptoms, and the diagnostic problems they raise in adults.
