[Isolated stenosing calcified lesions of the aorta]. / Les bourgeons calcifiés sténosants isolés de l'aorte.

ABSTRACT

Two cases of isolated calcified lesions of the aorta are reported. The first observation is that of a 25 years old man suffering from mild intermittent claudication predominant in the left leg. Radiological examination showed a calcified isolated lesion of the infra renal abdominal aorta. The patient underwent surgical treatment (thromboendarteriectomy) and was asymptomatic after 6 months. The second observation concerns a 30 years old man treated for benign thrombocytemia in whom a severe arterial hypertension associated with a thoracic bruit was discovered incidentally. Radiological workup demonstrated a solitary calcified lesion of the descending thoracic aorta. Endarteriectomy was performed and the patient was still asymtomatic at 12 months. A review of the literature as well as physiopathological hypothesis and diagnostic and therapeutic management of these uncommon lesions is proposed.
