OBJECTIVE Intraventricular hemorrhage (IVH) is a complication of prematurity often associated with ventricular dilation, which may resolve over time or progress to posthemorrhagic hydrocephalus (PHH). This study investigated anatomical factors that could predispose infants with IVH to PHH. METHODS The authors analyzed a cohort of premature infants diagnosed with Grade III or IV IVH between 2004 and 2014. Using existing ultrasound and MR images, the CSF obstruction pattern, skull shape, and brain/skull ratios were determined, comparing children with PHH to those with resolved ventricular dilation (RVD), and comparing both groups to a set of healthy controls. RESULTS Among 110 premature infants with Grade III or IV IVH, 65 (59%) developed PHH. Infants with PHH had more severe ventricular dilation compared with those with RVD, although ranges overlapped. Intraventricular CSF obstruction was observed in 36 (86%) of 42 infants with PHH and 0 (0%) of 18 with RVD (p < 0.001). The distribution of skull shapes in infants with PHH was similar to those with RVD, although markedly different from controls. No significant differences in supratentorial brain/skull ratio were observed; however, the mean infratentorial brain/skull ratio of infants with PHH was 5% greater (more crowded) than controls (p = 0.006), whereas the mean infratentorial brain/skull ratio of infants with RVD was 8% smaller (less crowded) than controls (p = 0.004). CONCLUSIONS Among premature infants with IVH, intraventricular obstruction and infratentorial crowding are strongly associated with PHH, further underscoring the need for brain MRI in surgical planning. Prospective studies are required to determine which factors are cause and which are consequence, and which can be used to predict the need for surgical intervention.

Initial Method

✓ Over a 3-year period, 11 premature infants with intraventricular hemorrhage and posthemorrhagic hydrocephalus were managed initially with prolonged external ventricular drainage via a subcutaneously tunneled catheter. The mean duration of drainage for this group was 20.7 days. Although two patients died before shunting was considered, no morbidity or mortality was observed to result from this technique. Seven patients required a shunt after stabilization of their medical problems. Two patients, followed for 24 and 40 months, have not required shunting procedures. External ventricular drainage via a subcutaneously tunneled catheter has been found to be a safe and reliable initial method of treating posthemorrhagic hydrocephalus in premature infants.

In Reply.— We appreciate the interest and comments of Drs Puccio and Soliani regarding our article "Blood Pressure Increase, Birth Weight Dependent Stability Boundary and Intraventricular Hemorrhage."1 In response, we address the following points: 1. Although mean blood pressure (BP) values greater than 100 mm Hg were observed in some of our patients, these were quite rare. The mean BP was found to be less than 60 mm Hg 99% of the time. Thus, unless one is recording BPs through long periods and sampling quite often, the brief spikes likely would not be observed.

To the Editor.— We have read with great interest the recently published article by Perry et al.1 The need to define "safe" blood pressure levels in the critically ill premature infants is a central topic in the prevention of intracranial hemorrhage. However, in Perry's paper maximum systolic blood pressure and maximum mean blood pressure values are much higher than those reported by previously published articles.2-4 High blood pressure values were reported by Lou and Friis-Hansen5 in nine newborns.

Objectives: Synthetic MRI can obtain multiple parameters in one scan, including T1 and T2 relaxation time, proton density (PD), brain volume, etc. This study aimed to investigate the parameter values T1 and T2 relaxation time, PD, and volume characteristics of intraventricular hemorrhage (IVH) newborn brain, and the ability of synthetic MRI parameters T1 and T2 relaxation time and PD to diagnose IVH.Materials and methods: The study included 50 premature babies scanned with conventional and synthetic MRI. Premature infants were allocated to the case group (n = 15) and NON IVH (n = 35). The T1, T2, PD values, and brain volume were obtained by synthetic MRI. Then we assessed the impact of IVH on these parameters.Results: In the posterior limbs of the internal capsule (PLIC), genu of the corpus callosum (GCC), central white matter (CWM), frontal white matter (FWM), and cerebellum (each p &lt; 0.05), the T1 and T2 relaxation times of the IVH group were significantly prolonged. There were significant differences also in PD. The brain volume in many parts were also significantly reduced, which was best illustrated in gray matter (GM), cerebrospinal fluid and intracranial volume, and brain parenchymal fraction (BPF) (each p &lt; 0.001, t = −5.232 to 4.596). The differential diagnosis ability of these quantitative values was found to be excellent in PLIC, CWM, and cerebellum (AUC 0.700–0.837, p &lt; 0.05).Conclusion: The quantitative parameters of synthetic MRI show well the brain tissue characteristic values and brain volume changes of IVH premature infants. T1 and T2 relaxation times and PD contribute to the diagnosis and evaluation of IVH.
