[Anatomopathology, physiopathology and treatment of the emphysematous disease of infants (apropos of an experience with 133 surgically treated cases)].

Infantile and childhood lobar pulmonary emphysema (LPE) has finally become a rather straightforward problem after 28 years experience and the important statistics published. Contrary to adult emphysema, and leaving aside the particular aspects of causal lesions, the pediatric form is usually a unilateral lobar or infralobar disorder, and therefore lends itself to surgical treatment.

[Accidents and complications during aorto-coronary bypass surgery. 100 cases].

Using a series of 100 patients undergoing aorto-coronary bypass surgery in the department of Professor MATHEY at Laennec Hospital, the authors analyse the incidence of accidents and complications during the per- and postoperative phases. Acute hypertensive crises accounted for the most common complication, occurring in 49 per cent of cases. The authors attribute these hypertensive crises to inadequate neuroplegia in the anaesthetic protocol. Other complications are analysed in relation to the type of myocardial protection.

[Risk factors in coronary artery bypass surgery. 55 observations].

The incidence of complications after aorto-coronary bypass surgery were studied in a series of 55 patients in relation to the duration of extra-corporeal circulation and the value of myocardial protection. The length of the period of extra-corporeal circulation played a significant role in the onset of complications whilst there was no significant difference between the group of patients operated upon under hypothermia and those in normothermia.

[Prevention of complications following aorto-coronary bypass surgery. Proposed solutions].

In the light of per- and post-operative complications seen in the past, the most suitable anaesthetic protocol for aorto-coronary bypass surgery would appear to be neuroleptanalgesia. This anaesthetic technique appears to decrease the incidence of per- and postoperative hypertensive crises. In addition, the use of cardioplegia also made it possible to decrease the incidence of postoperative complications in a recent group of 39 patients.

[Closure of ventricular septal defects. Comparison of 2 technics].

To be correctly done, closure of a ventricular septal defect must be sound, and must also avoid damage to the conducting tissue. These two essentials are somewhat contradictory, since in order to avoid the bundle of His in its position along the postero-inferior edge of the ventricular septal defect (VSD) in the membranous septum, the sutures inserted into this region must be superficial, and therefore weak. It is for this reason that the published series continue to show evidence of a significant number of post-operative shunts and atrio-ventricular blocks, as much in the closure of isolated VSDs as in the treatment of Fallot's tetralogy. This paper compares two techniques of suturing the prosthetic material which is used to close the VSD: the classical technique, in which it is intended to avoid the bundle of His by working below it, on the right side of the interventricular septum, and a different technique in which the sutures are applied directly to the free edge of the interventricular communication.

[Pacemakers in children].

This is a study of pacemakers in 32 children with permanent pacemakers, 7 of them for congenital block, and 25 for post-operative block, representing a total of 69 pacemaker implantations. After a brief survey of the results, there is a discussion of the problems of the indications, relative for the congenital blocks, and absolute for the surgical blocks after a short period of observation. The choice of type of pacemaker rests upon three essential features: minimum inconvenience, a good length of active life, and the facility of an increased rate. Recent technical progress has allowed these features to be combined. The pacemakers currently available are shown on a table. The results are to a large extent determined by extreme care being taken over the implantation; meticulous asepsis, a low threshold on the electrode test, a pacemaker which is "comfortable" in its site, all these are essential if the serious complications are to be avoided, namely infection and pacemaker failure. The best route for the child, as for the adult, is by way of an epigastric approach with an abdominal pocket. In the very small infant, it seems better to implant by left thoracotomy, and to site the pacemaker intrapleurally.

[Reconstruction of the pulmonary outflow tract with a valved conduit (author's transl)].

The authors describe 25 patients who underwent open heart surgery for reconstruction of the pulmonary outflow tract with a valved conduit. The following anomalies were observed: six cases of great vessels transposition, five cases of pulmonary artery atresia, five cases of truncus, three cases of tetralogy of Fallot and six cases of single ventricle. Two cases of single ventricle were treated in order to be transformed into a systemic ventricle. The pulmonary outflow was reconstructed with a valved conduit anastomosed between right atrium and pulmonary artery. This study includes pre- and postoperative hemodynamic values, surgical evaluation and a 5-months to 3-years follow-up. The authors emphasize that it is important that the surgical indications are closely related to the morphology and hemodynamics of pulmonary circulation for a better result.
