Venous hypertension has been implicated as an important factor in the pathogenesis of neonatal brain injury under a variety of circumstances, such as periventricular hemorrhagic infarction in the preterm infant [1], cerebrovascular injury after treatment with extracorporeal membrane oxygenation (ECMO) [2], and thrombosis of the superior sagittal sinus. Although duplex and color Doppler sonographic techniques have been used to evaluate the intracranial arterial tree for several years, little attention has been paid to the role of Doppler techniques in the evaluation of the cerebral venous system. We describe the appearance of the normal infantile cerebral venous system on color and duplex Doppler sonograms and present a spectrum of abnormalities in venous hemodynamics in critically ill infants with the goal of familiarizing readers with the clinical potential of this technique.
在多种情况下，静脉高压被认为是新生儿脑损伤发病机制中的一个重要因素，比如早产儿的脑室周围出血性梗死[1]、体外膜肺氧合（ECMO）治疗后的脑血管损伤[2]以及上矢状窦血栓形成。尽管双功和彩色多普勒超声技术已用于评估颅内动脉系统数年，但对于多普勒技术在评估脑静脉系统中的作用却很少有人关注。我们描述了正常婴儿脑静脉系统在彩色和双功多普勒超声图上的表现，并展示了危重症婴儿静脉血流动力学的一系列异常情况，目的是让读者熟悉这项技术的临床应用潜力。
