Visibility of tract: MRI and operative findingsa
| Tract | Visibility | LDM (n = 12) | CDS (n = 10) | P Value |
|---|---|---|---|---|
| Subcutaneous | 12 (100%) | 10 (100%) | – | |
| Intrathecalb | Entirely visible | 10 (83%) | 1 (10%) | .003 |
| Partially visible | 2 (17%) | 4 (40%) | ||
| Poorly visible | 0 (0%) | 4 (40%) |
↵a Data are number of patients, with percentages in parentheses.
↵b Because the tract of 1 patient with CDS was revealed to end in the dura mater at the operation and there was no tract in the intrathecal area, only 9 CDS tracts were assessed with regard to visibility and attachment site in its intrathecal portion.
