A rare case of abdominal aortic aneurysm developed after Bacillus Calmette-Guérin (BCG) therapy for bladder cancer. This complication, associated with psoas abscesses, was successfully treated with surgery and anti-tubercular therapy.
Area of Science:
- Urology
- Vascular Surgery
- Infectious Disease
Background:
- Bacillus Calmette-Guérin (BCG) is a standard treatment for early-stage bladder cancer.
- Complications of BCG therapy can include infectious processes.
- Abdominal aortic aneurysms (AAAs) are serious vascular conditions.
Observation:
- A 68-year-old man developed an abdominal aortic aneurysm after receiving BCG for bladder cancer.
- Imaging revealed psoas abscesses and a saccular infrarenal aortic aneurysm with hematoma.
- Surgical exploration confirmed a psoas abscess and hemorrhage.
Findings:
- The patient underwent aortic ligation and axillary-bifemoral bypass.
- Post-operatively, he received one year of anti-tubercular therapy.
- Clinical response to anti-tubercular therapy was observed.
Implications:
- This case highlights a rare but serious potential complication of BCG therapy.
- Early recognition and management of infectious complications are crucial.
- Multidisciplinary management involving urology, vascular surgery, and infectious disease is essential for such cases.
