A retrospective cohort study of computed tomography scans of AAA patients considered for repair, in order to identify sex specific differences in abdominal aortic aneurysm (AAA) metrics and the association between anatomical differences/features of complexity and adverse patient outcome.
A retrospective cohort study of computed tomography scans of AAA patients considered for repair. The study aims to, firstly, identify sex specific differences in abdominal aortic aneurysm (AAA) metrics utilising manual and automated image processing techniques; and secondly, if numbers are sufficient, explore the association between features of AAA complexity and adverse patient outcome.
Study Type
OBSERVATIONAL
Enrollment
1,000
Computed Tomography Angiography - Aorta Whole
Imperial College London
London, United Kingdom
Sex-specific differences in thrombus burden
Volumetric assessment of aortic thrombus
Time frame: Pre-operative CT
Sex-specific differences in anatomical complexity
Anatomical as assessed by current IFU (instructions for use) criteria. (Anatomy within pre-specified vessel diameter, length, tortuosity and calcification criteria for insertion of endovascular stent graft for AAA repair.)
Time frame: Pre-operative CT
Association between anatomical differences and adverse patient outcome for patients receiving operative repair - need for transfusion, risk of vessel injury, ischaemia (bowel or limb), renal injury and re-intervention/endoleak.
Post-operative outcomes
Time frame: 30 days
