[Treatment of recent traumatic ruptures of aortic isthmus (author's transl)].

We recommand the following procedure: --positionment of the patient allowing the simultaneous approach of left pleural cavity and left femoral vessels. --aortic liberation far away of the isthm, in a diffuse hematoma. --medullar protection by femoro-femoral extra corporeal circulation. --recovery of aortic continuity either by direct suture or by interposition of an prosthetic tube, the sutures being largely supported by mediastinal cellular tissue. We have used this technique in 5 patients, with a good result in all cases.

[Reintervention on heart valve prostheses. Apropos of 78 cases].

78 patients with one or more prosthetic heart valves were reoperated on between 1972 and 1978, and comprised 12% of the work load of valvular surgery. There were two postoperative periods in which the incidence of reoperation was high: the first year, 38%, and the period between the 5th and the 8th year, 41%. The main causes of reoperation could be divided into two groups: those common to all valves with paravalvular leaks (25%), endocarditis (12%) being the principal causes, and those associated with particular valves: deterioration of Beall prosthesis 33%, and thrombosis mainly affecting the Bjork and Beall prostheses (25%). The operative mortality was 12%. The fact that urgent operation is required in severe cases is underlined. In the light of these results, the surgical indications of reoperation should be discussed at an earlier stage. These indications are based essentially on the clinical condition of the patient and objective confirmation by further investigation should not delay the operation, which, in our experience, has never been unnecessary.

[Stenosis of the thoraco-abdominal aorta by endovascular calcification, with hypertension. Surgical treatment (author's transl)].

A case of a 24 year-old man in whom, following acute pulmonary oedema complicating hypertension known for a period of three years, stenosis of the thoraco-abdominal aorta produced by a large calcification within a zone of the aorta with an inflammatory appearance was demonstrated. This case is included within the context of the aortic syndrome. Operation led to normalisation of blood pressure immediately afterwords, but there was moderate hypertension 56 months later.

Bifocal cervical spondylodiscitis due to Citrobacter diversus.

Spondylodiscitis due to Citrobacter diversus is rare. An unusual case of bifocal cervical spondylodiscitis following transurethral prostatectomy is reported. C. diversus was detected by urinary cultures and locally by intervertebral disc puncture. Satisfactory recovery occurred after treatment with imipenem and amikacin, and then imipenem alone. Citrobacter infections are still rare in adults but are increasing in immunocompromised patients and sometimes occur in healthy subjects following surgery.

Thromboembolytic complications during circulatory assistance with a centrifugal pump in patients with valvular prostheses.

This article describes two patients with artificial heart valves who suffered thromboembolytic complications during circulatory assistance using a Biomedicus centrifugal pump. The first case involved a 25-year-old man who presented acute blockage of a mechanical aortic valve. Emergency surgery was performed to replace this valve with a bioprosthesis. Postoperatively the patient developed severe left heart insufficiency and a Biomedicus centrifugal pump was placed between the left atrium and the ascending aorta. After 3 days of total left ventricular assistance, weaning was started and successfully completed with explanation on the 5th day. Two days later the patient died of multiple coronary embolism with thrombosis of the valve. The second case involved a 30-year-old man. Six months before, he underwent surgical procedure with placement of Bio-prosthesis for dissecting aortic aneurysm due to annuloectasia. Upon admission for terminal dilated myocardiopathy, the patient was in kidney failure almost requiring dialysis. Because of this patient's size (Marfan syndrome), no donor heart was immediately available and left circulatory assistance with a Biomedicus pump had to be initiated. The patient lived without mechanical ventilation, in good clinical condition until day 23 when he presented acute right heart failure due to extensive valvular and coronary thrombosis. From these two cases, several important comments can be made about anticoagulation therapy, partial unloading of left ventricle, or need for biventricular assistance, and efficiency of centrifugal devices in these clinical applications.

[The fate of children who have undergone correction of Fallot's tetralogy. Report of fifty long term assessments (author's transl)].

50 children who had beneficied of repair of Fallot's tetralogy with a follow up of 2 to 11 years, were psychologicaly and physicaly evaluated. Work capacity tests were performed in 12 cases. Children with early repair (before 5 years of age) have a very better result. Preliminary palliative treatment cause worse results. Physical capacities are normal in the majority of children. Work capacity is not different from normal children. Repair before school age is the best way for a normal life.
