RESUMO
With the renewed interest in the use of autogenous radial arteries in coronary artery bypass grafting, concerns regarding vascular compromise and selection of patients have arisen. In this report, we describe a modification of Allen's test.

The history of surgery for ischemic heart disease is presented beginning with procedures to ablate nerves to the heart in the early part of this century. The evolution of surgical techniques to primary coronary artery bypass grafting is illustrated. Included are subtotal thyroidectomy, pedicle grafting of muscle, omentum, lung, stomach, and jejunum to the pericardium and heart, cardiopericardiopexy, ligation of the great cardiac vein, grafting from aorta to coronary sinus, implantation of arteries into the myocardium, coronary artery bypass grafting, and percutaneous transluminal coronary angioplasty.

Replacement of cardiac valves in children has been associated with high rates of mortality and morbidity in the past. We have compared 24 children from 2 to 18 years of age who have received mechanical valves with 24 children who have received porcine valves. The groups were similar except that (1) there were more mitral operations in the mechanical valve group and more aortic operations in the porcine valve group; (2) more porcine than mechanical valves were implanted in recent years; and (3) the porcine valve group comprised more young patients under 8 years and required more complex operations. Early and late mortality rates were higher in the mechanical than in the porcine valve group. Major late complications were seen in 50 percent of the mechanical valve group and 13 percent of the porcine group. Implantation of an adult-sized aortic valve was made possible in all patients by the use of aortic augmentation annuloplasty. Higher operative mortality rates in the mechanical valve group may have been related more to technique of myocardial preservation during operation than to type of valve. Although differing rates of late morbidity and mortality may also have been related to myocardial preservation and other technical factors, the type of valve used seemed to be an important determinant of the better results in the porcine group. Despite unknown durability of the porcine valve, our data suggest that the safest prosthetic valve to use in children at this time is the glutaraldehyde-fixed porcine prosthesis.

Four patients with atrial myxoma underwent successful surgical excision with the aid of cardiopulmonary bypass at the Medical University of South Carolina. This report describes their clinical manifestations and treatment with special emphasis on advances in surgical technique. This report also emphasizes the malignant potential of this tumor and reviews the recent literature.

Recurrence is the most common complication of spontaneous pneumothorax. Open thoracotomy with resection of obliteration of blebs and parietal pleurectomy provides the best protection against recurrence. Twenty-seven consecutive patients underwent open thoracotomy for recurrent pneumothorax with no mortality and minimum morbidity and have remained free from recurrence. We believe that thoracotomy should be more widely used in the treatment of what is called spontaneous pneumothorax, since this treatment may remove the real cause of the disease.
