Four cases of benign stricture of the oesophagus treated by reversed gastric tube oesophagoplasty are presented. The technique used is described in detail, and the advantages of this method over other ways of bypassing the oesophagus are discussed. The most important advantage is the restoration of normal deglutition with only one extrathoracic anasthomosis.
The relation between the length of the main left coronary artery and the presence of atherosclerosis in its branches or the presence of complete left bundle-branch block was studied by selective coronary arteriography in 43 persons. The length of the main left coronary artery was found to be significantly shorter in patients with coronary atherosclerosis than in subjects without angiographic evidence of coronary artery disease. In patients with electrocardiographic evidence of complete left bundle-branch block, the length of the left main coronary artery was significantly shorter than that in both previous groups. In view of these findings, it is suggested that a short main left coronary artery should be considered as a congenital factor predisposing to the development of coronary artery disease. The possible mechanisms leading to atherosclerosis of the left coronary arterial branches in the presence of a short main trunk are discussed.

In this experimental study seventeen dogs subjected to pulmonary embolism were treated with either saline, heparine or streptokinase. Regional blood distribution was calculated in both, the healthy and infarcted lung tissue by means at the sequental injection of radioactive microspheres. Results of fibrinolytic treatment compare favourable over heparine or saline administration.
