[Severe coronary insufficiency in a young woman after mediastinal radiotherapy].

Three years after radiotherapy to the mediastinum for Hodgkin's disease, a 28 year old female presented with incapacititating angina. The presence of severe disease in the proximal arteries on coronary arteriography, with obliteration of the anterior descending artery and, of the right coronary artery, together with an unstable collateral circulation, constituted an indication for a double aorto-coronary bypass graft. A review of the literature suggests that early development of atherosclerosis may be produced by the synergistic action of radiotherapy and lipid disorders. Fifteen similar cases have been described, eight of them in patients of less than 40 years of age; three were discovered at post-mortem examination in patients aged under 21.
