Cerebral embolism may complicate lesions of the subclavian arteries or aortic isthmus distal to the origins of the vertebral or carotid arteries. This may be due to retrograde propagation of occlusive thrombus. In other cases the vessels are patent but there are periods of reverse blood flow, creating a potential for reflux of embolic material to the ostia of the neck vessels.

Two cases of pulmonary arteriovenous fistula were treated by local anatomical dissection and excision. This technique is preferable to pulmonary resection when the fistula is localised and superficially situated. The feeding vessels must be included in the resection to avoid possible recurrence. The history of the surgical removal of arteriovenous fistulae is discussed, and the reasons for preferring local excision are given.

Case histories of three young women who suffered small bowel infarction associated with oral contraceptives and progestational agents are presented. Two infarctions were due to superior mesenteric artery thrombosis and one to superior mesenteric vein thrombosis. All of these patients were of blood group A and smokers, factors which are known to predispose to vascular thrombosis. A study was made of 18 additional cases reported in the literature. It was found that many of these cases presented with a history of symptoms of 2 weeks of more and at operation some of the cases appeared to be reversible. One case was reported where apparent reversion of the process of vascular thrombosis occurred after cessation of the oral contraceptive.

Pulmonary blastoma is the rarest malignant tumour of the lung. Two more cases are reported and the literature is reviewed. The first case, a woman, is the longest recorded survivor. An examination of all the reported cases shows that the tumour is less common and less agressive in women.
