[Surgical treatment of pulmonary metastases. Apropos of 26 cases].

Twenty-six patients with known primary tumors were treated surgically for pulmonary metastases between 1951 and 1979. The metastases were diagnosed more often (58% of cases) by routine radiological examinations than because of thoracic symptoms. While diagnosis of the primary tumor and the metastases was simultaneous in three cases, the average lapse of time between the two diagnoses was 5 years and 1 month in the other cases.

[Metastatic pulmonary echinococcosis secondary to a primary cardiac lesion situated in the interventricular septum. One case successfully treated surgically (author's transl)].

The authors report a case of metastatic pulmonary echinococcosis secondary to a primary cardiac lesion. The diagnosis was made on the basis of round pulmonary lesions developing during an episode of cardiac diseases which had been labelled as idiopathic acute pericarditis. The septal site then suspected on the basis of minor conduction disturbances was confirmed by angiography and could be excised under extracorporeal circulation.

[Comparative study of mechanical and manual suture of bronchial stumps in pneumonectomy (author's transl)].

The incidence and time of onset of bronchial fistulae were retrospectively studied in 306 patients who underwent pneumonectomy at the Saint-Joseph Hospital, Paris, between 1975 and 1979. The bronchial suture was performed mechanically in 145 cases and manually in 161 cases. Patients in both groups were of comparable age, lung disease, side operated upon, nature of the bronchial division, post-operative course and surgeon's ability.

[Bronchial myoblastoma with cartilage injury (author's transl)].

The authors present a new case of bronchial myoblastoma the particularity of which is the partial destruction of bronchial cartilages. This unusual aggressivity of the tumor facing the toughest bronchial structures does not seem to be an unfavourable prognosis element. Two years after resection, the tumor hasn't recurred.

[A comparative study of "slowly resorbed suture material" in the rat with tracheal sutures (author's transl)].

The authors studied the outcome of polyglycotic acid and braided polyglactine suture material used on the trachea of the rat. The compared them with two non-self-resorbing sutures. 61 rats were operated.

Surgical treatment for a complicated congenital aortic stenosis. The association of a three-level obstruction of the left ventricular outflow tract with mitral incompetence, coarctation of the aorta, and the Wolff-Parkinson-White syndrome.

We report a case of complex congenital aortic stenosis with obstruction at all three levels of the left ventricular outflow tract (subaortic, aortic, and supravalvular aortic stenoses) associated with a mitral malformation, coarctation of the aorta, and the Wolff-Parkinson-White syndrome. The subaortic stenosis was corrected by excision and myotomy, and the supravalvular stenosis by a widening prosthetic operation with a Dacron patch extending as far as the aortic ring, at which level a Björk-Shiley No. 17 aortic prosthesis was inserted.

[Treatment of mitral insufficiency by Wooler-Reed annuloplasty. Remote results].

The outcome of 67 patients operated on between 1963 and 1971 for pure mitral regurgitation due to dilatation of the mitral ring (group I: 25 cases), papillary muscle dysfunction (group II: 11 cases) and valvular and/or subvalvular lesions (group III: 31 cases) was analysed with an average follow up of 9.1 years (range 4 to 12 years). Eleven patients (16 p.

[Total anomalous pulmonary venous return: apropos of an unusual case].

A case is reported in which the entire pulmonary venous return was abnormal, being retro-cardiac. Unusual features were the age at which the abnormality was discovered (14 years), and the anatomical type of abnormality of pulmonary venous return. The return effectively emptied into a posterior cavity which was "a diverticulum of the right atrium" which had a wide communication with the "normal" right atrium, which in turn communicated with the left atrium by a highly placed Ostium Secundum.

[Aortic valve replacement. Apropos of a series of 117 patients].

With a series of 117 aortic valve replacements, the authors have examined the results in relation to the method of protecting the myocardium while the aorta is clamped off. There does not appear to be much difference between coronary perfusion and the technique of profound local hypothermia by the perfusion of a chilled solution into the pericardium. Because of this, the authors remain in favour of the latter technique, which provides effective protection of the myocardium during periods of aortic occlusion sufficient for monovalvular replacements.
