28. American and British Thoracic Surgery

George A. Mason, Wooler, Northumberland, England.

The Atlantic has been no barrier to the influence by workers on either side of the ocean on the other. Modern communications have made this intimacy closer. A common language and a somewhat similar outlook have been significant factors. Differences and contrasts may make our relatively feeble efforts seem poor shadows of the achievements of our American "cousins," but nevertheless we may have made useful contributions to that common pool of thought and experience upon which progress largely depends. The American Association for Thoracic Surgery has brought together your workers for now more than fifty years. The Journal has enabled us to keep au fait with your work. Our members have long appreciated the privilege of being associated with your Advisory Editorial Board. The Society of Thoracic Surgeons of Great Britain & Ireland was founded in 1933 and from the outset received every encouragement from you. Indeed probably every one of our meetings has had its American participants. The founders of both our organizations were men whose names are indicative of milestones in Thoracic Surgery. Those who followed have contributed most of its principal advances and it augurs well for the future that during the formative stages of their careers men from the British Isles are working in North American clinics - and vice versa.

29. The Surgical Treatment of Dextrocardia with Inversion of the Ventricles and Double Outlet Right Ventricle

The surgical treatment of the commoner congenital cardiac malformations has become established. Few unusual or complex deformities remain to be explored. One of these is the interesting condition known as dextrocardia with inversion of the ventricles with both great vessels originating from the morphologic right ventricle, and with pulmonary stenosis. Six patients seen at the Mayo Clinic have been diagnosed during life to have this complex anomaly. Three of these patients were sufficiently disabled to warrant surgical repair. A complex intracardiac repair was successful in two of the three patients. Repair was accomplished in the first by ligation of the main pulmonary artery, closure of the ventricular septal defect and construction of an extracardiac shunt between the morphologic left ventricle and the pulmonary artery. In the second case the repair was accomplished entirely from within the heart, using an angioplastic procedure to shift the origin of the pulmonary artery toward the morphologic left ventricle. In the last case die additional associated defect of situs inversus of the atria required a re-direction of pulmonary venous return within the atria (Mustard procedure), as well as closure of the ventricular septal defect so as to direct blood appropriately into the great arteries.

30. Management of War Wounds of the Chest

Sponsored by Robert H. Wylie

From July 1st, 1965 to June 30, 1966, 427 patients with intrathoracic wounds were received at USAF Hospital Clark. They arrived from 6 hours to 61 days after injury. Eighteen percent of these patients were admitted with pneumothoraces. The treatment of hemopneumothorax has primarily been intercostal tubes (93.2%). Only 2.1% were treated by thoracentesis alone while 4.7% had no treatment. The incidence of emergency thoracotpmies was 9.3%, all performed in the Republic of Viet Nam. The indications are discussed. The incidence of early elective thoracotomy was 11.4%. The indications for these operations are, (1) evacuation of significant blood and clot from pleural space and, (2) removal of foreign bodies. Eleven patients were received who had survived missile wounds of the heart, 3 of whom had emergency thoracotomies with suture of myocardial defects. The incidence of thoracoabdominal incisions was 8.0% of 75 patients with combined thoracic and abdominal wounds. The mortality rate for the series was 2.8%. However, only one death occurred in those patients with just thoracic trauma.
