Surgical treatment of childhood pleural empyema.

From June 1977 to January 1987, 175 patients underwent surgical treatment of childhood pleural empyema. The surgical treatment consisted of tube drainage in 159 (90%) cases, decortication in 31 (17%) cases, pleuropneumonectomy in 2, lobectomy in 1, and partial thoracoplasty in one cases. There were 2 hospital deaths (14 and 26 days after admission). Late recurrences didn't occur, except in one case where a partial thoracoplasty was necessary. During the follow-up of 11 to 120 months (mean 32 months) examinations were done by chest radiographs. We believe that, children with loculated empyema can be treated successfully with antibiotics and chest tube drainage in early stage. The tube drainage is a more effective method than the other surgical procedures. Few patients require open drainage, and further surgery is rarely required.

[Surgical treatment of pleural mesothelioma].

Mesothelioma which is the primary tumor of the pleura has recently been subject to many researches because of its poor prognosis and the difficulties met in radical therapy. Between 1974-1986 total 46 patients with pleural mesothelioma were treated surgically at our center. Finally it was concluded that only the cases in stage I and with epithelial malignant pleural mesothelioma should be subjected to radical surgery. The remaining patients should be treated with conservative methods.

[Pulmonary and mediastinal bronchogenic cysts].

Bronchogenic cysts are relatively rare anomalies with a congenital origin resulting in an abnormal branching of the tracheo-bronchial tree. They either develop in the pulmonary parenchyma or in the mediastinal region. Between 1975 and 1987, 21 cases of bronchogenic cysts were operated upon. Eighteen of these cysts had a pulmonary localisation and 3 were mediastinal. Only 8 of these were diagnosed pre-operatively by bronchoscopy. The major reason for delay in diagnosis is persistent or recurrent pulmonary infection. Eight cases were treated by cystectomy, 4 by simple wedge resection, 4 by segmental resection, 3 were extirpated and 2 by lobectomy.

Surgical treatment of bronchial adenomas: results of 29 cases and review of the literature.

The low-grade malignant potential of bronchial adenoma has been widely reported in the medical literature. During the past 12 years we have treated 29 patients with this disease, 18 (62%) of whom required conventional lobectomy or pneumonectomy, because most of our cases had come to our center after having inappropriate treatments in other centers and loosing time. In these cases we observed either a total obstruction of a bronchus or a destroyed parenchyma due to recurrent pulmonary infections. For this reason, the number of pulmonary resections is more important than conservative surgical procedures in our center. The other 11 cases (38%) were treated by bronchoplasty or more conservative resectional procedures. There was no recurrence and the survival rate was about 96 per cent at 5 years. We believe that, in our series, we would have mostly been able to perform conservative types of resections if we could have diagnosed the disease in its early stages.

Management of a large pseudo-aneurysm secondary to balloon angioplasty for aortic coarctation.

Balloon dilation of native aortic coarctation has been employed safely and effectively in selected patients and with good results during follow-up. However, pseudo-aneurysm formation at the site of dilatation occurs in about 2%-8% of patients. Although the majority of these aneurysms remain stable, they occasionally may increase in size during follow-up, raising concerns in regard to potential rupture, massive bleeding, and death. We report a case of aneurysm formation after balloon dilation of native coarctation of the aorta, treated successfully with the interposition of a tube graft.

Internal thoracic artery as main blood supply to the lower limbs. Case report.

A 70-year-old male patient was admitted with symptoms of unstable angina pectoris and claudication. He presented critical left main and right coronary artery disease and juxtarenal aortic occlusion at the same time. Internal thoracic artery increased in diameter with many collateral branch arteries distally. Coronary artery bypass graft operation was performed immediately. Saphenous veins were used for conduit. Internal thoracic artery was let intact to avoid any ischemic problem of the lower extremities. DSA performed postoperatively showed that the internal thoracic artery was the unique blood supply to the leg. In the absence of emergency of peripheral revascularization two staged surgical approach (CABG first and aortobifemoral bypass some months later) was considered. However, in patients with severe peripheral vascular disease or even in patients whom intraaortic balloon-pump indicated postoperatively, combined surgical approach is necessary. In all coronary artery disease patients with Leriche syndrome, ITA dependent lower extremity circulation should be thought preoperatively. Extra-anatomic peripheral bypass is a reasonable alternative choice in combined procedures with low morbidity, especially in elderly patients having coexisting disease.

Right ventricular outflow tract reconstruction for tetralogy of fallot with abnormal coronary artery: experience with 35 patients.

BACKGROUND: An abnormal coronary artery crossing the right ventricle outflow tract (RVOT) complicates complete repair of tetralogy of Fallot (TOF). We have evaluated surgical options for RVOT reconstruction for this group of patients. METHODS: Between 1984 and 2002, 35 TOF patients with abnormality of coronary arteries underwent total correction. Age of these patients ranged from 1 to 14 years (mean 5.8 +/- 2.8 years). All patients were diagnosed by echocardiography and 25 patients had cardiac catheterization. All the abnormal coronary arteries were spared at the operation. In 24 patients a transannular patch was applied for RVOT reconstruction. In three patients with an adequate pulmonary annulus, oblique ventriculotomy incisions, and in two patients, transatrial approaches were performed. "Two-patch" technique was chosen for two patients. In four patients placement of an extracardiac conduit was necessary. RESULTS: Mortality was observed in four patients, in two of them due to suspected myocardial ischemia. None of the surviving patients needed reoperation. All of them were in NYHA class I. The follow-up period for patients without extracardiac conduit was between 14 and 96 months (mean 50.2 months) and for the patients with extracardiac conduit ranged 36 to 98 months (63.5 months). The mean gradients measured by echocardiography were, respectively, 5 mmHg (range 0 to 35 mmHg) and 23.75 mmHg (range 20 to 25 mmHg). CONCLUSIONS: Definitive repair of TOF patients with abnormal coronary arteries can be performed in early childhood, but care should be taken to leave at least 1 cm of myocardium between the sutureline and the abnormal coronary artery. Detailed evaluation of the patients preoperatively is mandatory to identify the strategy and timing of the operation.

Neurogenic tumours of the mediastinum: a report of 60 cases.

OBJECTIVES: To analyze retrospectively 60 patients (13 infants and children, 47 adults--21 men and 39 women) with mediastinal neurogenic tumours admitted to Atatürk Centre for Chest Disease and Chest Surgery, Ankara, Turkey between 1988 and 1999. This comprised 21.2% of 283 patients who had surgical operations for all mediastinal masses during the same period. PATIENTS AND METHODS: The patients ranged from four to 67 years of age. Thirteen patients were younger than 15 years and 47 were 15 years of age or older. Medical records were reviewed for demographic data, clinical presentation, diagnostic investigations, operative procedures, and tumour location and invasion. Postoperative morbidity and mortality were noted as well as long term follow-up. The clinical investigations included chest x-ray and computed tomography of the thorax in all patients, and spinal magnetic resonance imaging and bronchoscopical examination in some. Clinical variables were compared. RESULTS: The tumours had the following characteristics: 42 (70%) were nerve sheath tumours; 15 (25%) were autonomic ganglion tumours; two (3.6%) were paragangliomas; and one (1.4%) was a malignant peripheral neuroectodermal tumour (Askin's tumour). Nerve cell tumours comprised the majority of tumours in infants and children (nine of 13, 69%), whereas the nerve sheath tumours were most frequent in adults (39 of 47, 83%). There were 48 benign and 12 (20%) malignant tumours when all age groups were considered; the malignancy rate was 61.5% (eight of 13) in children and 8.5% (four of 47, P<0.05) in adults. All patients were operated via a posterolateral thoracotomy. Surgical resection of the tumour was complete in 56 of 60 patients (93.3%). Resection of malignant tumours was grossly incomplete in four cases (four of 12, 33.3%). All benign tumours were totally excised. There were two major complications (respiratory failure and pulmonary emboli) and 14 minor complications in the perioperative period. The mean follow-up period was five years and seven months. Tumours recurred in 5.3% (three of 56) of patients who had a complete resection initially. There were no late deaths related to benign tumours. CONCLUSIONS: Complete resection of tumours can be performed safely by a thoracotomy approach and is important for achieving satisfactory long term survival in most mediastinal neurogenic tumours.
