Treatment delays for patients exiting an aortic aneurysm surveillance programme.Oram BJ, Buckenham TM, Roake JA, Lewis DR Department of Radiology, Christchurch Hospital, Christchurch, New Zealand. BACKGROUND: We have previously reported abdominal aortic aneurysm (AAA)-related mortality in patients who have completed surveillance. This study investigates the journey time of patients who exited the AAA surveillance programme at Christchurch Hospital and underwent elective repair to determine the factors contributing to the interval between completing surveillance and undergoing surgical repair. METHODS: A retrospective review of patient notes was carried out for 25 patients who underwent elective repair of their AAA after exiting the surveillance programme between November 2000 and September 2005. RESULTS: The median time interval between exiting the programme and undergoing repair for patients fit for repair was 6 months. During this waiting period, there were two aneurysm-related deaths. Analysis of the patient journeys showed that those with significant comorbidity, that is, patients who required additional investigation by other clinicians (n = 7), had a median time to repair of 35 weeks. This was substantially increased compared with a median time of 22.5 weeks to repair for the rest (n = 18). CONCLUSION: At our institution the median time for completion of surveillance to repair was 6 months. An AAA with a diameter of 55 mm has an expected risk of rupture of 5%, with mortality approaching 90%. In our series, mortality was 4.9% (two patients died while awaiting repair), consistent with expected figures. Factors contributing to this delay of 6 months to repair were identified. Modifications to this journey are suggested to improve the time interval and therefore hopefully reduce the aneurysm-related mortality in this group.
