<h3>BACKGROUND AND PURPOSE:</h3> The anatomy of the deep venous system is characterized by a great variability that might play an important role in pathogenesis brain lesions preterm brain. aim this study was to compare cerebral subependymal veins evaluated on SWI venography 3 groups neonates with normal MR imaging (very [gestational age &lt;32 weeks], moderate-to-late ≥32 ≤37 and term &gt;37 weeks]) evaluate influence birth development veins. <h3>MATERIALS METHODS:</h3> venographies 84 very preterm, 31 50 were retrospectively evaluated. Subependymal vein classified into 6 different patterns: type 1 represented classic pattern types 2–6 considered anatomic variants. A χ² test used differences between distributions patterns. <h3>RESULTS:</h3> significant difference (<i>P</i> = .011) noticed patterns based gestational age. Type more frequent (68%) than both (41.7%) (56.5%). Anatomic variants common (66%) (41%) (36%). Interhemispheric asymmetry (59.5%) (51.6%) (34%; <i>P</i> .017). Sex monozygotic twin did not significantly affect frequency .0962). <h3>CONCLUSIONS:</h3> neonatal shows large spectrum higher neonates, likely related epigenetic factors development.
