Angiography in patients with abdominal aortic aneurysms
Southern Medical Journal
|June 1, 1981
Summary
Preoperative angiograms reveal significant abnormalities in most patients undergoing abdominal aortic aneurysm repair. These findings frequently alter surgical plans, improving patient care.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Cardiovascular Medicine
Background:
- Abdominal aortic aneurysms (AAAs) are a significant vascular disease.
- Preoperative assessment is crucial for planning AAA repair.
- Angiography plays a key role in evaluating associated vascular abnormalities.
Purpose of the Study:
- To assess the prevalence of angiographic abnormalities in patients undergoing elective aneurysmorrhaphy.
- To determine the impact of preoperative angiography on operative planning for AAA repair.
Main Methods:
- Retrospective analysis of angiograms from 61 consecutive patients.
- Patients were evaluated for elective aneurysmorrhaphy at Gainesville VA Medical Center.
- Data collected included renal artery stenosis, aberrant arteries, other aneurysmal disease, and occlusive disease.
Main Results:
- Renal artery stenosis occurred in 33% of patients.
- Aberrant or multiple renal arteries were found in 26%.
- Other aneurysmal disease (iliac) was present in 51%, and occlusive disease in 30%.
- Preoperative angiograms altered the operative plan in 72% of cases.
- A single complication (retroperitoneal hematoma) was recorded.
Conclusions:
- A significant majority of patients with abdominal aortic aneurysms exhibit angiographic abnormalities.
- Preoperative angiography frequently impacts and modifies the surgical approach for AAA repair.
- Angiography is essential for comprehensive preoperative evaluation in AAA patients.
