Filter by:The study is aimed at investigating whether repair of endoleak type II can be improved by adding navigation technology. Can this technology increase precision by guiding the needle that punctures through the skin as used during the repair procedure? Can the procedure logistics be improved by using navigation technology instead of computed tomography (CT) guidance of the needle puncture? Parameters logged during the procedure: - was the needle placement successful? - number of needle punctures? - time used on guidance procedure - X-ray exposure dose
This study will be a cross-sectional survey of interobserver variability associated with contrast enhanced ultrasound (CEUS) to detect endoleaks using computed tomographic angiography (CTA) as the practice standard. The investigators will enroll 40 consecutive patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). At the first follow-up visit after the procedure, participants will undergo two abdominal ultrasound examinations with and without contrast, and one CTA. Analyses will be conducted to examine interobserver variability in the detection and characterization of endoleaks using contrast-enhanced ultrasound (CEUS). Other endpoints include examination of sensitivity and specificity of CEUS compared to CTA, and characterization of the number and types of endoleaks detected.
After endovascular treatment of an abdominal aortic aneurysm, lifelong imaging follow-up is needed to monitor the effectiveness of the treatment. One parameter in this follow-up is endoleak, which is leakage of blood into the aneurysm sac. The aim of this study is to investigate the value of magnetic resonance imaging using Vasovist as a contrast agent for the detection of endoleaks.
