Abstract:
We present three cases of infection of the native aorta following angiography. The infection was an incidental finding at operation in two patients, while a third presented with fulminant sepsis. All had debridement of the retroperitoneum and underwent successful extraanatomic bypass. We feel caution is warranted in placing a retroperitoneal graft even in suspected aortic sepsis. Prophylactic antibiotics may be advisable to protect against infection of atherosclerotic plaque during angiography.
Insights
Aortic infections following angiography are rare but serious complications. Prompt debridement and extraanatomic bypass are crucial for successful treatment, with caution advised for retroperitoneal grafts.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Interventional Cardiology
Background:
- Angiography is a common diagnostic procedure involving catheter insertion into blood vessels.
- Native aortic infections are infrequent but potentially life-threatening complications.
- Atherosclerotic plaques may be susceptible to infection during invasive procedures.
Observation:
- Three cases of native aortic infection post-angiography are presented.
- Two infections were incidental findings during surgery; one presented as severe sepsis.
- All patients underwent retroperitoneal debridement and successful extraanatomic bypass.
Findings:
- Extraanatomic bypass proved effective in managing these rare aortic infections.
- Retroperitoneal graft placement requires careful consideration in cases of suspected aortic sepsis.
- Prophylactic antibiotics during angiography may reduce the risk of plaque infection.
Implications:
- Highlights the risk of native aortic infection after angiography, emphasizing diagnostic and surgical considerations.
- Suggests a need for heightened awareness and potentially modified prophylactic strategies in high-risk patients.
- Informs surgical planning for aortic sepsis, advocating for cautious graft placement and considering alternative bypass routes.
