Abstract

To evaluate the value of contrast-enhanced ultrasound (CEUS) using a high-end ultrasound system in the characterization of endoleaks after endovascular aortic repair (EVAR). In this mono-center study, 41 patients were retrospectively analyzed after being examined using a modern high-end ultrasound system (RS80A with Prestige, Samsung Medison Co., Ltd., Seoul, Korea). The maximum diameters of the aneurysms were measured in two planes (right-left and ventral-dorsal). The performance of Color Doppler in comparison to CEUS was evaluated and CEUS was considered as the gold standard in endoleaks detection. 41 patients were included in the study. Between June and December 2016, mostly male patients (n = 38; 92,7%) were examined, corresponding to the incidence of abdominal aortic aneurysms in the population. Average age was 75±8 years (range 58-100 years). Average diameter of the treated aneurysm-sacs was 5,04±1.5 cm (range 2.7-10.5 cm) in the right-left plane and 4,75±1.36 cm (range 2.8-8.9 cm) in the ventral-dorsal plane. Using CEUS as the gold standard endoleaks could be detected in 28 patients (68,3%) with 13 patients not showing an endoleak after EVAR. Color Doppler showed a sensitivity of 32.1%, a specificity of 92.3%, a positive...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
