A review of cranial ultrasound examinations performed on 426 newborns over a 42-month period demonstrated a predominance of left-sided germinal matrix hemorrhage over both right-sided and bilateral germinal matrix hemorrhage. Distribution of intraventricular or intraparenchymal hemorrhage did not show this pattern. The reasons for left-sided predominance of germinal matrix hemorrhage remain speculative, and perhaps are related to cerebrovascular anatomic differences or to hemodynamic stresses related to patency of the ductus arteriosus.
对426名新生儿在42个月期间进行的头颅超声检查回顾显示，左侧生发基质出血比右侧及双侧生发基质出血更为常见。脑室内或脑实质内出血的分布未显示出这种模式。生发基质出血左侧占优势的原因仍属推测，可能与脑血管解剖差异或与动脉导管未闭相关的血流动力学压力有关。
