Size matching in lung transplantation.

Volume concordance between donor lungs and the chest cavities of transplant recipients has important perioperative and postoperative implications. Between December 1987 and August 1991, 90 patients underwent lung transplantation in the Joint Marseilles-Montreal Lung Transplantation Program: 51 patients had double lung transplants, 19 patients had single lung transplants, and 20 patients had heart-lung transplants. There were 18 children (age range, 7 to 17 years) and 72 adults (age range, 18 to 58 years). Size matching was based on measurement of the submammary thoracic perimeter. Patient age (+/- 2 years) was also taken into consideration in children. Airway anastomoses were bronchial except for all heart-lung transplant patients and two double lung transplant patients, who had tracheal anastomoses. Occasional differences between donor and receiver bronchial diameters in children (greater donor size twice and smaller donor size once) required bronchoplasty in three instances. Healing was normal in these three instances, and no bronchial stenoses were noted. Performance of separate sutures rather than continuous running sutures on the cartilaginous anterior portion facilitated correction of airway diameter inequalities in adults. Excess volume was noted in three patients during closure of the thorax. In one patient, donor and recipient thoracic perimeters were similar. In two patients, however, donor size was greater by more than 20%. This was corrected by pneumoreduction with a surgical stapler. Lung size was decreased by 10% to 40% with use of this technique. Thoracic closure was facilitated and hemodynamic instability was thus corrected. No functional abnormalities were noted after surgery once the differences in lung size were corrected.(ABSTRACT TRUNCATED AT 250 WORDS)

[Epidemiological study of pulmonary hydatid cyst in the Ivory Coast. 3 cases].

No cases of echinococcus have been reported up to this time in Ivory Coast, where it has been considered non-existant in either pulmonary or hepatic form. The three cases of pulmonary echinococcus reported here show the classic paucity of clinical symptoms associated with classical radiological findings. The epidemiological research confirms in one case definite infection occurring in Ivory Coast and the other two either in the Ivory Coast or in closely neighbouring areas.

[Post-infarct posterior aneurysm of the left ventricle. Apropos of a successful surgical case in an African].

The authors report the first case in the literature of a post-infarction left ventricular (LV) aneurysm operated in a black African man of 31 years. The episode of infarction had been ignored, and the patient presented a posterior LV aneurysm with moderate mitral insufficiency and heart failure. The diagnosis was made by a cineangiogram in the LV and a coronary angiogram showing a total obliteration of the right coronary. The patient underwent a resection of the aneurysm with closure of the LV-aneurysm communication. Six months after surgery, the patient was asymptomatic and the size of the heart had decreased. With regard to this unique case, the authors discuss the literature on LV aneurysms in African, and on coronary atherosclerosis in Africa. They discuss also the surgical indication in case of post-infarction LV aneurysm.
