Management of Currarino Triad
Currarino triad requires a multidisciplinary surgical approach with specific interventions for each component of the triad (anorectal malformation, sacral bony defect, and presacral mass) to optimize morbidity, mortality, and quality of life outcomes. 1
Diagnostic Evaluation
- MRI is essential for characterizing the presacral mass and determining the exact nature and extent of the lesion before surgery 2
- Evaluate for:
- Tethered cord syndrome (present in many cases) 3
- Hydrocephalus (may be present in some cases) 3
- Specific type of presacral mass (meningocele, teratoma, or dermoid/epidermoid cyst) 1
- Sacral bony defect (typically "scimitar sacrum" or sacral agenesis) 1
- Anorectal malformation (stenosis, agenesis, or fistula) 1
Surgical Management Algorithm
1. Anorectal Malformation Management
- For anal stenosis: Initial management with anal dilatation 3
- For severe anorectal malformations: Temporary colostomy may be required 3
- For Hirschsprung's disease (when present): Rectal biopsy and appropriate surgical correction 3
2. Presacral Mass Management
For anterior sacral meningocele:
- Posterior approach via lumbar and sacral partial laminectomy-laminoplasty
- Transdural ligation of the neck of the meningocele 3
For solid tumors (teratoma, dermoid/epidermoid cyst):
3. Tethered Cord Management (when present)
- Surgical untethering during the same procedure as presacral mass removal 3
4. Hydrocephalus Management (when present)
- Appropriate neurosurgical intervention (shunting or endoscopic third ventriculostomy) 3
Position Considerations for Surgery
- For males: Prone position is standard for posterior sagittal anorectoplasty (PSARP) 2
- For females: Consider supine position as an alternative (anterior sagittal anorectoplasty) 2
- Important caveat: Supine lithotomy position provides better access to explore the presacral space, especially with deeply located cysts 2
Follow-up and Monitoring
- Regular neurological assessment to detect any new deficits 3
- Imaging to ensure no recurrence of presacral mass 3
- Bowel function monitoring and management 3
- Long-term follow-up is essential (average follow-up in successful cases: 6 years) 3
Special Considerations
- Dual pathology: In rare cases, the presacral mass may contain both meningocele and teratoma, requiring careful surgical planning 4
- Infection risk: Spinal abscess can occur as a complication, requiring reoperation and medical therapy 3
- Genetic counseling: Although most cases are sporadic, familial transmission has been reported 3
Outcomes
With appropriate surgical management, patients typically show improvement with:
- No additional neurological deficits
- No recurrence of presacral mass
- Improved bowel function
- Stabilization of symptoms 3
Pitfalls to Avoid
- Overlooking the characteristic notched sacrum (sacral scimitar) on plain X-ray, especially with small sacral defects 2
- Inadequate exposure of deeply located presacral masses due to inappropriate positioning 2
- Incomplete excision of presacral masses with dual pathology 4
- Failure to address all components of the triad 1
