Postoperative surveillance after surgical repair of abdominal aortic aneurysms: Abdominal aortic aneurysm: diagnosis and management: Evidence review V.

Show details
Review question 27How frequently should people be monitored for postoperative complications, further aneurysm expansion and aneurysm rupture after EVAR or open repair of an abdominal aortic aneurysm?
ObjectivesTo determine appropriate intervals for monitoring of people who have undergone surgical repair of an abdominal aortic aneurysm; that is, how frequently people should be monitored to detect complications (endoleak, graft migration, graft kinking, incisional hernia, graft occlusion and aortic neck expansion), further aneurysm expansion and aneurysm rupture)
Type of reviewIntervention
LanguageEnglish

Review strategies

Appropriate NICE Methodology Checklists, depending on study designs, will be used as a guide to appraise the quality of individual studies.

Data on all included studies will be extracted into evidence tables. Where statistically possible, a meta-analytic approach will be used to give an overall summary effect.

All key findings from evidence will be presented in GRADE profiles and further summarised in evidence statements.
