“…When compared with diameter measurements derived from computed tomography angiography (CTA), systematic underestimation has been reported for ultrasound [27,28]. In addition to modality-associated influences, examiner-dependent influences, such as the angulation of the transducer and patient-dependent (physiological) pulsationrelated deviations of up to 4 mm between systole and diastole add to variations in the assessment of the aortic diameter [29].…”

Background An abdominal aortic aneurysm (AAA) is defined as a localized dilatation of the abdominal aorta of ≥ 3 cm. With a prevalence of 4–8 %, AAA is one of the most common vascular diseases in Western society. Radiological imaging is an elementary component in the diagnosis, monitoring, and treatment planning of AAA patients. Method This is a narrative review article on preoperative imaging strategies of AAA, incorporating expert opinions based on the current literature and standard-of-care practices from our own center. Examples are provided to illustrate clinical cases from our institution. Results and Conclusion Radiological imaging plays a pivotal role in the initial diagnosis and monitoring of patients with AAA. Ultrasound is the mainstay imaging modality for AAA screening and surveillance. Contrast-enhanced CT angiography is currently considered the gold standard for preoperative imaging and image-based treatment planning in AAA repair. New non-contrast MR angiography techniques are robustly applicable and allow precise determination of aortic diameters, which is of critical importance, particularly with regard to current diameter-based surgical treatment guidelines. 3D imaging with multiplanar reformation and automatic centerline positioning enables more accurate assessment of the maximum aortic diameter. Modern imaging techniques such as 4D flow MRI have the potential to further improve individualized risk stratification in patients with AAA. Key points:

“…The B-mode ultrasound (realtime gray scale sonography) is the method of choice for screening. Ultrasound measurement of both aortic diameter and the measurement plane must be standardized to facilitate comparative examinations and valid followup examinations [22]. This leading-edge method has provided the most accurate results.…”

Short version of the S3 guideline on screening, diagnosis, therapy and follow-up of abdominal aortic aneurysms On 3 July 2018, under the leadership of the German Society for Vascular Surgery and Vascular Medicine (DGG), the new S3 guidelines for screening, diagnosis, treatment, and follow-up for abdominal aortic aneurysms (AAA) were adopted by the DGG Executive Board, after unanimous approval by all participating profes

The ruptured abdominal aortic aneurysm (AAA) has still a high hospital mortality rate of about 50 % (intervention and non-corrective treatment combined). With an easy non-invasive and inexpensive measure such as the ultrasound screening rupture threatened aneurysms can be recognized in time and then treated prophylactically, hemorrhagic shock can be avoided. Screening programs in England and Sweden currently describe an AAA prevalence of 1.5 % among screened 65-year-old males. With an absolute risk reduction for aneurysm-related death of 15.1 per 10,000 men invited for screening and a cost of £ 7,370 per quality-adjusted life year (QALY), screening for this target group is highly cost-effective. Comprehensive AAA screening requires defined criteria for the quality of the aortic ultrasound examination and for the surgical treatment of detected large AAA. These interventions should be concentrated in centers obligated to quality registry documentation. Patients with smaller AAA, requiring no repair, should be included in a surveillance program, also with registry of their long-term data.
