Attitude à tenir devant un anévrysme de l'aorte abdominale sous-rénale

: This update, intended for cardiologists, is not concerned with technical surgical considerations but rather considers the problems facing the physician in abdominal aortic aneurysm (AAA). 1) What form does AAA take: an atheromatous, spindle-shaped and partially thrombotic ectasis. 2) How is it detected: traditionally by clinical examination and increasingly by ultrasound. 3) What additional examinations are useful: the most simple and commonly repeated is ultrasound. Aortic angiography is useful only in cases with a surgical indication. 4) What is the risk of spontaneous development: above all, rupture, the statistical risk of which becomes considerable once the diameter of the aneurysm exceeds 6 cm. 5) What are the risks and results of surgical treatment: it has become an operation presenting little danger and one that beyond all doubt increases life expectancy. 6) Which patients should undergo surgery: all aneurysms dating from more than 6 cm and/or showing symptoms.
