Summary
A novel trans-sacral-foramen approach offers a safer and easier method for draining presacral abscesses. This minimally invasive technique provides the shortest path to the abscess, improving patient outcomes.
Area of Science:
- Minimally invasive surgery
- Interventional radiology
- Infectious disease management
Background:
- Presacral abscesses are common in developing countries, often requiring drainage.
- Computed tomography (CT)-guided percutaneous drainage is a recommended alternative to surgery.
- The presacral space presents anatomical challenges for accessing abscesses.
Observation:
- A novel trans-sacral-foramen approach was used to drain a residual presacral abscess in a 47-year-old woman.
- The procedure involved CT guidance and catheter insertion through the sacral foramen.
- The patient was positioned prone, and a one-step technique was applied.
Findings:
- Magnetic resonance imaging (MRI) after 2 weeks showed significant abscess reduction.
- Catheters were removed, and 18-month follow-up MRI indicated intervertebral fusion.
- The trans-sacral-foramen approach proved to be the shortest and safest route.
Implications:
- This approach simplifies drainage of difficult-to-access presacral abscesses.
- It offers a potentially safer and more effective alternative to existing methods.
- Further research may establish this as a standard treatment for presacral abscesses.
