Abstract:
The diagnosis of low grade prosthetic graft infection or aorto-enteric fistula is difficult using conventional radiographic imaging modalities. We report a case of aorto-enteric fistula to the sigmoid colon diagnosed by the new technique of 18-fluorodeoxyglucose positron emission tomography.
Insights
Diagnosing low-grade prosthetic graft infections, like aorto-enteric fistulas, is challenging with standard imaging. A new 18-fluorodeoxyglucose positron emission tomography technique successfully identified an aorto-enteric fistula to the sigmoid colon.
Area of Science:
- Vascular Surgery
- Diagnostic Imaging
- Nuclear Medicine
Background:
- Low-grade prosthetic graft infections and aorto-enteric fistulas pose diagnostic challenges.
- Conventional radiographic imaging often lacks sensitivity for these conditions.
Observation:
- A case of aorto-enteric fistula involving the sigmoid colon was encountered.
- The patient presented with symptoms suggestive of graft infection.
Findings:
- 18-fluorodeoxyglucose positron emission tomography (FDG-PET) was utilized as a novel diagnostic approach.
- FDG-PET imaging successfully diagnosed the aorto-enteric fistula.
Implications:
- FDG-PET may offer improved diagnostic accuracy for prosthetic graft infections.
- This technique could enhance the early detection and management of aorto-enteric fistulas.
- Further research into FDG-PET for graft complications is warranted.
