Relationship between hydrocephalus etiology and clinical outcome
| Clinical Outcome | Hydrocephalus | |||
|---|---|---|---|---|
| PAS(n = 11; 28.9%) | SAS(n = 18; 47.4%) | AC(n = 6; 15.8%) | CH(n = 3; 7.9%) | |
| No improvement(n = 6; 15.8%) | 1 (2.6%) | 4 (10.5%) | 1 (2.6%) | |
| Partial Improvement(n = 17; 44.7%) | 3 (7.9%) | 12 (31.6%) | 1 (2.6%) | 1 (2.6%) |
| Good outcome(n = 13; 34.2%) | 7 (18.4%) | 5 (13.2%) | 1 (2.6%) | |
| Clinical worsening(n = 2; 5.3%) | 1 (2.6%) | 1 (2.6%) | ||
Note.—PAS indicates primary aqueduct stenosis; SAS, secondary aqueduct stenosis; AC, Arnold Chiari malformation; CH, communicating hydrocephalus.
