The modified Blalock-Taussig shunt: clinical impact and morbidity in Fallot's tetralogy in the current era.
The Blalock-Taussig shunt is considered a low-risk management option for palliation in tetralogy of Fallot, but the morbidity associated with a Blalock-Taussig shunt can have a significant impact on patient care. We reviewed the outcome for this operation in the current era. ⋯ Pulmonary artery hypoplasia and angiographic evidence of pulmonary artery distortion are common after initial palliation by a modified Blalock-Taussig shunt. Neonatal palliation was associated with significantly smaller pulmonary arteries before repair, which necessitated additional interventions.

From January 1980 to December 1993, 52 patients underwent surgical-resection for tumors involving the sternum. The series included 20 primary malignant tumors, 4 desmoid tumors, 2 malignant tumors infiltrating the sternum from adjacent organs, 19 local recurrences or metastases of breast tumors, and 7 metastases of other tumors. Total sternectomy was performed in 5 patients, subtotal sternal resection in 19, and partial resection (less than 50% of the sternum) in 28. Concurrent en bloc resection included anterior ribs in 37 patients, clavicle in 11, lung in 12 patients, pericardium in 7, and diaphragm in 2. The chest was reconstructed with prosthetic material and a myocutaneous flap in 26 patients (50%), prosthetic material only in 12 patients (23%), a myocutaneous flap in 5 patients (10%), and other techniques in the remaining patients. In 47 patients (90%) the resection was radical, and in the remaining 5 patients it was palliative. ⋯ Our experience demonstrates that sternal resection is a safe and effective treatment, which may improve the patient's quality of life and achieve a long-term survival not only in primary tumors but also in selected secondary malignant tumors of the sternum.

Clinical Trial Controlled Clinical TrialLow-dose amiodarone-related complications after cardiac operations.
High-dose preoperative amiodarone therapy has been implicated as a risk factor for serious complications after cardiac operations. To investigate the effect of preoperative low-dose amiodarone treatment on early postoperative outcome after cardiac operations, we prospectively studied 88 patients. ⋯ Preoperative low-dose amiodarone therapy does not seem to be related to significant postoperative lung toxicity, but it is associated with various cardiac complications and an increased need for more intense inotropic support after cardiac operations. These findings may be related to the drug's depressant effect on the myocardium.
