Diese Studie verglich den Durchmesser der Bauchschlagader mittels axialer Computertomographie und Duplexsonographie bei Patienten mit abdominellem Aortenaneurysma.


Von 01/2002-12/2004 wurden 322 Patienten mit Abdominalaortenaneurysma mit Computertomographie und Duplexsonographie untersucht und der Durchmesser des Aneurysmas erhoben.


Der Durchmesser war 56,17 mm mittels Computertomographie und 53,44 mm mittels Duplexsonographie. Die Computertomographie zeigte gröβere Durchmesser in 97,83 % der Patienten.


Im Vergleich zur Duplexsonographie ist der Durchmesser des abdominellen Aortenaneurysmas in der axialen Computertomographie gröβer.


The aim of this study is to assess differences between axial computed tomography and duplex ultrasound, based on measurements of maximal aortic diameter in patients with abdominal aortic aneurysms.


From January 2002 until December 2004, 322 patients were admitted with an abdominal aortic aneurysm. All of them underwent abdominal duplex ultrasound scanning and computed tomography by separate laboratories in order to determine the maximal aortic diameter. The computed tomography technologists were blinded to all duplex results and vice versa.


Mean computed tomography maximal aortic diameter was 56.17 mm and mean duplex maximal aortic diameter was 53.44 mm. Computed tomography measurements were greater than duplex in 97.83% of the patients.


Axial computed tomography consistently overestimates the maximal aortic diameter measurements in patients with abdominal aortic aneurysms compared with duplex ultrasound.
