A review of the management of 239 patients with sternal fractures in a busy trauma center between October 1989 and May 2000 was undertaken to determine the incidence, significance, morbidity, and mortality of this injury. There were 140 men and 99 women with a mean age of 50.3 years (range, 15 to 93 years). Sternal fractures accounted for 8% of admissions for thoracic trauma. ⋯ Four patients (1.7%) underwent surgery. The results show that isolated sternal fractures have low associated morbidity and mortality. Admission is justified for the management of pain and treatment of cardiac complications and concomitant injuries.

Total reconstruction of the mitral valve with autopericardium: anatomical study.
Mitral valve repair has several advantages over prosthetic valve replacement. A new technique of total reconstruction of the mitral valve with autologous pericardium is described. The native mitral valve leaflets and chordae were excised from 10 human cadaver hearts, in the same way as for prosthetic valve replacement. ⋯ The new valve was fashioned and inserted in the native valve position. Hydraulic probes showed good competence in all 10 reconstructed mitral valves. This method might be a good alternative to prosthetic valve replacement.

Case ReportsRight heart assist during beating bypass for severe left ventricular dysfunction.
Three patients with triple-vessel disease and severe left ventricular dysfunction underwent successful revascularization on a beating heart, using a right ventricular assist system. Heparin-coated circuits with a centrifugal pump provided 2.5 to 3.5 L x min(-1) of flow to maintain good hemodynamics and enable easy access to the posterior vessels during vertical displacement of the heart.

Case ReportsBronchial artery dissection and fatal hemothorax following pneumonectomy.
A 59-year-old man died suddenly and unexpectedly two days after an uncomplicated pneumonectomy for bronchogenic adenocarcinoma. In addition to a distal pulmonary thromboembolism found at postmortem, there was significant hemorrhaging into the pneumonectomy space, which was associated with rupture of a dissecting aneurysm in the calcified bronchial artery stump. The pathology and surgical implications of bronchial artery disease are discussed.

Thymoma associated with pure red-cell aplasia: clinical features and prognosis.
As information on the clinical features and prognosis of thymoma complicated by pure red-cell aplasia is limited, follow-up data on thymoma patients who had a thymectomy between 1954 and 1999 were analyzed retrospectively. Six of 166 cases were complicated by pure red-cell aplasia. In 3 of these, the pure red-cell aplasia appeared after surgical intervention. ⋯ The other 4 patients subsequently died from pure red-cell aplasia. The outcome in patients with pure red-cell aplasia was poorer than that in the entire group of patients with thymoma and in those with thymoma complicated by myasthenia gravis. The possible onset of pure red-cell aplasia after thymectomy should be kept in mind during follow-up.
