Stanford type A aortic dissection in a hypertensive patient with atherosclerosis of aorta and aortitis.

Dissection of aorta is a serious condition; the main factors are hypertension and diseases of the connective tissue or of collagen. Aortitis syndrome in combination with hypertension and atherosclerosis in association with ascending aortic dissection is rarely seen. We present the case of a 53-year-old hypertensive patient whose ascending aortic dissection was associated with pericardial effusion without rupture of the aorta and with pleural effusion. Several unusual aspects of transesophageal echocardiography are described. The intraoperative biopsy revealed inflammatory aortitis with mural hematoma, without giant cells. The literature concerning aortic dissection and aortitis is reviewed.

[A new technical procedure for middle and lower lobe lobectomy].

Among combined pulmonary resections, one of the most difficult operations is right middle and lower lobe lobectomy because of the very intricate anatomical relations between the three pulmonary lobes. Technical difficulties during the first-stage approach to the pulmonary artery in the fissure are compounded by the presence of pathological processes (neoplasm, suppuration, etc.) which provoke adhesions between the pulmonary artery and the bronchus, with inevitable major risks. A new technique for middle and lower lobe lobectomy which avoids the frequent accidents during this operation is described. The first stage involves ligature and section of the inferior root of the superior pulmonary vein and liberation of the horizontal fissure. Opening of the horizontal fissure exposes the superior fissural vein, which is then displaced towards the upper lobe. This allows access to the pulmonary artery in the fissure, together with its branches to the lower and middle lobes, and the fissural arteries to the upper lobe. This procedure enables simple dissection and ligature of the pulmonary artery, as at this level it is not adherent to the intermediary part of the bronchus. The triangular ligament, inferior pulmonary vein, and intermediary bronchus are then ligatured and sectioned. The advantages of this method consist in the simplification of the dissection, ligature, and section of the pulmonary artery in the fissure, and the need to apply only one ligature if there are no anatomical variations (common dorsal fissural and inferior apical artery, or common ventral fissural and middle lobe artery).

[Corrective surgery of congenital chest malformations of the type Pectus excavatum and Pectus carinatum (author's transl)].

The authors presents an original process for surgical treatment of deformations of chest anterolateral wall, insisting on the procedures and techniques of the recommended process. The compulsory operative steps are: wide chondrectomy, retrosternal loosening, transversal osteotomy of the sternum and contention with retrosternal metallic plates. The author considers surgery to be necessary for all these anterolateral chest deformations and the best age for their correction to be after 10 to 12 years. The original technique for loosening and preserving the perichondrium in its wholeness is described together with the complete resection of deformed cartilages.

[Bilateral pulmonary resections for bilateral bronchiectasis].

The present paper reports on 6 cases of bilateral bronchiectasis in patients aged 11 to 63 years, treated by simultaneous bilateral pulmonary resection and 1 case of bilateral bronchiectasis in which 14 segments were resected successively. Surgery by simultaneous bilateral approach and associated resection of the affected areas is a procedure that should be indicated, in the authors' opinion, only in carefully selected cases in which not more than 13 segments have to be resected. The indications and contraindications of surgery in bilateral bronchiectasis are discussed, preference being given to the simultaneous approach. In the cases reported at most 11 1/2 segments of the four pulmonary lobes affected were resected in a single stage; in 1 case 14 segments were resected successively, the resection exceeding in amplitude all similar one published until now. The immediate and late postoperative evolution (lesional and functional) were favourable, which pleads for a reconsideration of the approach to bilateral bronchiectasis and the application of the surgical treatment recommended, within the limits described.
