[Aortic dissection and Horton's disease. 2 cases].
The authors report two cases of temporal arteritis complicated with dissecting aneurysm of the aorta. The first one is discovered on systematical physical examination, the second is revealed by a thoracic pain. Clinical course is favourable under steroid therapy in both cases. Eleven cases of such complication with pathological control are reported in literature. Physiopathological mechanisms are discussed and active inflammatory involvement of aortic wall seem to be the main cause.
