title: [Post-radiation coronary diseases. Presentation of 7 cases and review of the literature].
abstract: Coronary lesions are one of the complications of mediastinal radiotherapy; they are more uncommon, at least in their clinical expression, than the involvement of the pericardium, but they are interesting by their gravity and occurrence in young patients (35 years old, in an average). We are reporting 7 cases in addition to the 53 already recorded in the literature. The neoplasm which led to the radiation treatment is, in 85 p. cent of the cases Hodgkin's disease and in 10 per cent of the cases a breast cancer. The time of occurrence of the clinical signs is of 5 years, in an average. The revealing symptom is an initial necrosis or an angor, most often unstable (45 p. cent of the cases, for each of them), more exceptionnally it is a sudden death or a pericarditis. The coronary risk factors have been determined in 37 patients; 45 p. cent had none. In half of the cases, the coronary involvement is monotruncular and frequently proximal (the anterior interventricular trunk is affected twice as often as the right coronary); in the other half, there is an equal distribution between bi-troncular and tri-truncular involvement. There are various pathological lesions: typical with isolated fibrosis of the intima and aventitia, pure atherosclerotic lesions or association of the two. The prognosis of these coronary lesions is severe (43 p. cent of deaths), but the patients who underwent revascularization procedures (by-pass or more seldom transluminal angioplasty) have in 80 p. cent of the cases a favorable evolution.(ABSTRACT TRUNCATED AT 250 WORDS)
