Reversible Pulmonary Hypertension due to Combined Fistula between the Left Anterior Descending Artery (LAD) and Pulmonary Artery and Severe Stenosis of the LAD.

Coronary artery fistulas are usually diagnosed accidentally without the presence of any symptoms. On the other hand, the combination of fistula between the left anterior descending artery (LAD) and pulmonary artery (PA) and severe stenosis of the LAD, as in this case report, is a potential life-threatening condition. A 72-year-old patient was treated surgically after being diagnosed with fistula between the LAD and PA, severe stenosis of the LAD, and severe pulmonary hypertension. In following paragraphs, the case of this man and significant issues regarding the development and management of coronary artery fistulas are analyzed.

Incidental finding of lung cancer in a patient with thoracic aortic aneurysm - simultaneous management. A case report.

The simultaneous existence of thoracic aortic aneurysm and lung cancer is a rare finding, especially if the malignancy is primary and does not involve the aortic wall. In this report, we present a case of a typical descending thoracic aneurysm combined with a primary adenocarcinoma of the left lower lobe. The aneurysm was repaired with a Dacron graft without use of extra corporeal circulation and a typical left lower lobectomy was performed. In such cases, aneurysms should be treated primarily with endovascular stents. However, if this is not possible, a combined operation can be performed with good outcome.

Ki-1 lymphoma with cardiac involvement at initial presentation.

Anaplastic large cell lymphoma is a rare malignancy in childhood. We describe the case of a 6-year-old boy with Ki-1 lymphoma of the thymus who presented with an endocardiac mass. The first histologic analysis suggested a high-grade undifferentiated sarcoma, but reevaluation and immunohistochemistry confirmed the CD30+ lymphoid derivation of the process. The patient was given chemotherapy and 24 months later he remains in complete remission. It is noted that echocardiography was repeated many times to detect heart lesion.

[Pulmonary arborization abnormalities in complex forms of pulmonary atresia with ventricular septal defect: unification, unifocalization and complete repair]. / Défauts d'arborisation pulmonaire des formes complexes d'atrésie pulmonaire à septum ouvert:unification, unifocalisation et réparation complète.

The presence of intrapulmonary arborization abnormalities in patients with pulmonary atresia and ventricular septal defect remains a therapeutic challenge. The aim of this study was to assess the value of procedures of pulmonary unifocalization, i.e. pulmonary unification, remodelling of the central pulmonary arteries and creation of an unifocal pulmonary blood supply, thereby resulting in complete repair. From october 1989 to october 1995, 27 unifocalization procedures were performed in 19 patients. The number of pulmonary segments dependant on non-communicating systemico-pulmonary collaterals was 14.7 +/- 5.4 per patient. The number of non-communicating systemico-pulmonary collaterals was 3.4 +/- 1.2 per patient. The Nakata index was 71 +/- 83 mm2/mm2. There were 3 deaths after an unifocalization procedure (mortality rate 15.8%). In 12 patients (63.2% of cases) a pulmonary arterial tree compatible with a complete repair was obtained. Eight complete repairs, with no mortality, following one or several pulmonary unifocalization procedures with a right to left ventricular systolic pressure ratio of 0.61 +/- 0.12 (range 0.4 to 0.75). Pulmonary unifocalization increases the recruitment of pulmonary segments and thereby the possibilities of complete correction in forms of pulmonary atresia with ventricular septal defect and arborization abnormalities of the pulmonary arterial tree.

Tetracycline compared with mechlorethamine in the treatment of malignant pleural effusions. A randomized trial.

Pleural sclerosis after tube thoracostomy was performed in 40 patients with malignant pleural effusions. The patients were randomly allocated to intrapleural therapy with tetracycline or mechlorethamine. Follow up was obtained on each patient to determine if a symptomatic effusion recurred. The response was classified as a complete or partial response and failure. (Complete response: complete lack of reaccumulation of pleural fluid for at least 60 days. Partial response: small pleural effusion asymptomatic not requiring further treatment for at least 60 days. Failure: all other cases). Tetracycline produced complete or partial control of the effusion in 16 of 20 trials for a duration of 6.1 +/- 4.1 months (range 2-14 months). Mechlorethamine produced control of the effusion in 12 of 20 trials for a duration of 4.4 +/- 1 months (range 2-8 months). These findings indicate that intracavitary tetracycline is a more effective treatment than intracavitary mechlorethamine for the control of neoplastic pleural effusion.
