Comparison of clinical and imaging factors to hemorrhagic rate on SWI in white matter lesions
| Variables | Number of cases | Median percentage of hemorrhage in white matter lesions (%) | p value |
|---|---|---|---|
| Gestational age (pre-/full-term) | |||
| Preterm | 17 | 59.1 | 0.06 |
| Full-term | 7 | 20.0 | |
| Age at MRI (early/TEA) | |||
| Early | 12 | 64.9 | 0.13 |
| TEA | 12 | 32.3 | |
| Main pattern of injurya | |||
| GMH-IVH | 8 | 93.9 | <0.01 |
| WMD | 14 | 14.2 | |
| Unilateral parenchymal hemorrhage | |||
| Presence | 5 | 87.8 | 0.05 |
| Absence | 19 | 40.9 | |
| Cystic evolution | |||
| Presence | 6 | 48.8 | 0.72 |
| Absence | 18 | 46.7 | |
| Grade by Sie | |||
| Grade 3 | 5 | 0.0 | 0.13 |
| Grade 4 | 19 | 55.6 | |
| Grade by Childs | |||
| Grade 1 or 2 | 14 | 39.7 | 0.59 |
| Grade 3 or 4 | 10 | 54.1 | |
TEA term equivalent age, GMH-IVH germinal matrix hemorrhage/intraventricular hemorrhage, WMD subtle to severe white matter damage
aTwo infants was excluded for analysis because equal distribution of GMH-IVH and WMD was found
