| Popis: | Introduction Following recommendations from the National Abdominal Aortic Aneurysm Screening Programme (NAAASP), an audit was performed to assess the impact of measuring inner rather than outer aortic wall diameters during scans for abdominal aortic aneurysm. Methods Inner and outer aortic wall diameters were taken from a prospective series of 302 patients attending the Vascular Studies Unit at the Leicester Royal Infirmary for routine ultrasound screening or surveillance of their abdominal aorta. Absolute differences, as well as the potential impact on patient management, were assessed. Results The mean difference between measuring techniques was found to be 1.6 mm (95% CI 1.59–1.61 mm). Aortas close to the threshold for surgery were referred on average 8.7 months later than if their outer wall dimensions had been used. Additionally, 1.6% of aortas were considered normal using inner wall measurements, but aneurysmal when measured using the outer aortic walls. Conclusion Mean differences between the two measurement techniques are small and well within acceptable levels of observer agreement. There is currently no evidence to suggest that a delay in aneurysm surgery of around nine months has a detrimental effect to either mortality or morbidity rates. Those patients falling just below the threshold for aneurysm (2.5–3.0 cm) remain a subject of review. |
