Taussig-Bing anomaly and arterial switch: aortic arch obstruction does not influence outcome.
Aortic arch obstruction is a commonly associated problem in the Taussig-Bing anomaly. Between 1983 and 1995, 28 consecutive patients with Taussig-Bing anomaly underwent arterial switch operation with baffling of the left ventricle to neoaorta. Group A: 11/28 had associated aortic arch obstruction. Group B: 17/28 had isolated Taussig-Bing anomaly. We assessed whether the coexistence of subpulmonary ventricular septal defect and aortic arch obstruction pose an incremental risk factor. ⋯ 1. Aortic arch obstruction has not adversely affected early or late survival (P>.05) or late functional class. 2. Patients with Taussig-Bing anomaly and aortic arch obstruction may have a higher reoperation rate than those with normal arch anatomy. 3. Taussing-Bing anomaly, with or without aortic arch obstruction, can be repaired with arterial switch operation during the neonatal period with good outcome.

Open chest (OC) and subsequent delayed sternal closure (DSC) has been described as a useful method in the treatment of the severely impaired heart after cardiac surgery. ⋯ This study shows that OC with DSC is a beneficial adjunct in the treatment of postoperatively impaired cardiac function, profuse hemorrhage and persistent arrhythmias. It can be performed without increased sternal morbidity. Long-term results are also encouraging.

Clinical Trial Controlled Clinical TrialThe effect of pentoxifylline on the lung during cardiopulmonary bypass.
Cardiopulmonary bypass (CPB) produces an inflammatory response due to the interaction of blood with a foreign body surface. The lungs are most affected by this inflammatory response. Pentoxifylline (PTX), a phosphodiesterase inhibitor and an inhibitor of leukocyte activation, is used to minimize damage in lungs where leukocytes play an important role. ⋯ The alveolar-arterial PO2 gradient increased after the CPB in both groups but a moderate decrease was observed 2 h postoperatively. In lung biopsy specimens taken before and after the CPB, there was marked leukocyte sequestration in the control group, whereas the number of leukocytes was seen to be insignificant in the PTX group (P < 0.005). This dosage regimen of PTX inhibits the postoperative increase in PVR and greatly minimized leukocyte sequestration in the lung due to CPB.

Value of body plethysmography in preoperative assessment of thoracotomy candidates.
The usefulness of body plethysmography in the assessment of thoracotomy candidates is not well documented. Reported thresholds for operability are generally expressed in absolute values, which do not take into account a patient's size, age or gender. Spirometric and plethysmographic data of 103 patients undergoing thoracotomy were examined for their ability to predict death due to cardiopulmonary insufficiency, pneumonia, and atelectasis during the first 30 postoperative days. ⋯ The prevalence of cardiac risk factors was high, so the decision for invasive hemodynamic studies should rather be based upon a patient's history than restricted to patients with impaired lung function. Because of methodological differences, and probably insuitable reference values, body plethysmography cannot substitute for spirometry. For FRC and FRC to total lung capacity (FRC/ TLC) ratio, further investigations must be undertaken to establish a correct reference value.

Transsternal transpericardial operations in the treatment of bronchopleural fistulas after pneumonectomy.
Between 1972 and 1993, 19 patients (15 males and 4 females) with bronchopleural fistulae and pleural empyema after pneumonectomy were treated with transsternal transpericardial operations and closure of the fistula. The underlying malignant disease was a non-small cell carcinoma in 12, a malignant epithelial mesothelioma in two, and an atypical carcinoid tumor in one case. One patient each presented with tuberculosis, chest trauma, and lung destroyed by bronchiectasis. ⋯ Two patients died in the first 30 days, of renal or respiratory failure without fistula recurrence. In two cases the fistula recurred; definitive healing was achieved using a great omentum flap and endoscopic application of fibrin glue and bone spongiosa. Transsternal transpericardial management of bronchus stump fistula after pneumonectomy is highly effective and offers advantages over the direct approach through the infected empyema cavity.
