Zur Diagnostik des infrarenalen Bauchaortenaneurysmas (BAA) stehen verschiedene Verfahren zur Verfügung: Palpation, Röntgenübersichtsaufnahme, Aortographie, Computer-Tomographie und Sonographie. Als einfache höchst zuverlässige Methode, die eine dreidimensionale Erfassung und Größenbestimmung eines BAA einschließlich der Abbildung älterer Wandthromben ermöglicht, hat sich die Sonographie erwiesen. Die Treffsicherheit liegt bei 98%. Bei der postoperativen Sonographie nach prothetischem Aortenersatz lassen sich Früh- und Spätbefunde unterscheiden: Alter Aneurysmasack, postoperative Hämatome, Prothesendilatation, Prothesenabknickung, Protheseninfektion und Hydronephrosen. Auch diese Veränderungen lassen sich nichtinvasiv und korrekt bei entsprechender Beachtung der Klinik sonographisch darstellen.
