Insights
A patient with low back pain and intermittent claudication had an abdominal aortic aneurysm (AAA) and aorto-iliac disease. Surgical repair with an aorto-bifemoral bypass graft successfully treated the chronic contained rupture (CCR).
Area of Science:
- Vascular Surgery
- Infectious Disease
- Radiology
Background:
- A 63-year-old male presented with chronic low back pain and bilateral intermittent claudication.
- Imaging revealed a 4 cm abdominal aortic aneurysm (AAA), severe aorto-iliac disease, psoas collection, and vertebral erosion suggestive of spondylodiscitis.
Observation:
- Lumbar spine MRI suggested spondylodiscitis at L4-L5.
- Initial antibiotic treatment for suspected infection was unsuccessful.
Findings:
- A chronic contained rupture (CCR) of the posterior aortic wall was identified during surgery.
- The patient underwent successful repair with an aorto-bifemoral bypass graft.
Implications:
- This case highlights the importance of considering AAA in patients with back pain and claudication.
- Surgical intervention is crucial for managing complex AAA with associated spinal pathology and infection.
- Successful aorto-bifemoral bypass grafting can effectively treat AAA and aorto-iliac occlusive disease.
Abstract:
A 63-year-old Caucasian male presented with a 4-month history of low back pain associated with bilateral intermittent claudication. A contrast enhanced CT scan demonstrated a 4 cm abdominal aortic aneurysm (AAA), along with severe bilateral aorto-iliac disease, a right psoas collection, and extensive vertebral erosion. An MRI of the lumbar spine suggested spondylodiscitis at L4-L5. After an unsuccessful and prolonged course of antibiotics, a decision was ultimately made to repair the aneurysm and bypass the aorto-iliac disease. Intra-operatively, a chronic contained rupture (CCR) involving the posterior aortic wall was encountered and repaired with an aorto-bifemoral bypass graft.
