RESUMO
Aneurysms of aortocoronary saphenous bypass grafts are an unusual and rare complication of coronary artery bypass surgery. Approximately 30 such cases have been reported in the literature. Atheromatous aneurysms usually appear late (more than 10 years after grafting). They are usually asymptomatic, but may manifest for investigation as a lesion altering the mediastinal contour. We report a further case of an atherosclerotic aortocoronary saphenous vein graft aneurysm in which the patient presented with angina due to aneurysmal compression of the host vessel.

A review of paediatric brainstem gliomas (BSGs) treated in the Department of Radiation Oncology of the University of the Witwatersrand teaching hospital group is presented. Eleven patients between the ages of 4 years and 9 years were seen in the period 1982-1992. Of these cases, 9 were diffuse, 1 focal and 1 exophytic; the radiological features classifying these primary brainstem tumours are described. The survival from initiation of treatment was longest for the exophytic type BSG (72 weeks), while little difference in survival between the 9 diffuse type BSGs (mean 21.5 weeks) and the single focal type BSG (21 weeks) was found. The treatment is described and the role of hyperfractionated radiotherapy is reviewed.

The complication of intracranial placement of a nasogastric tube in patients with complex facial and skull base fractures is rarely seen. A case report of a patient with complex craniofacial injury after trauma in whom a computerized tomogram scan showed passage of a nasogastric tube via a fracture of the anterior cranial fossa floor into the skull vault is presented. This case stresses the caution to be exercised in the emergency room resusitation of patients with craniofacial injury requiring nasogastric tube placement.
