Posthaemorrhagic ventricular dilatation (PHVD) in very preterm infants carries a poor prognosis. As earlier studies have failed to show a benefit of early intervention, it is recommended that PHVD be first treated when head circumference is rapidly increasing and/or when symptoms of raised intracranial pressure develop. Infants with PHVD, admitted ...

The surgical treatment of posthemorrhagic hydrocephalus (PHH) in low-birth-weight infants (LBWI) is debated. In a few cases, hydrocephalus progresses rapidly and requires early drainage, but valves and ventriculostomy have a high rate of complications in the early phase. Temporary valveless shunt (VLS) is proposed as an alternative treatment of acute ...

Hydrocephalus is an increase in cerebrospinal fluid volume that can be caused by a variety of etiologies. The most common connatal and acquired causes of hydrocephalus are spina bifida, aqueduct stenosis, and preterm low birthweight infants with ventricular hemorrhage. In general, the literature suggests mild neuropsychological deficits associated with hydrocephalus, ...

Neonatal alloimmune thrombocytopenia results from platelet-antigen incompatibility between mother and fetus, leading to antibody-mediated destruction of fetal platelets. With a prevalence of 1 in 1000 births, approximately 4000 infants born in the United States each year develop neonatal alloimmune thrombocytopenia. Ten to 20% of affected neonates develop intracranial hemorrhage, with ...

Shunt failure remains a disheartening complication of shunt surgery. The number of adjustable factors in attempting to reduce the rate is small. The clinical presentation and timing of shunt malfunction are well documented. Although the shunt design trials have been negative to date, valves have important effects that have not ...

BACKGROUND: Spontaneous intracranial haemorrhage is not common in infants, with differences from adults in both aetiology and severity. The infantile CNS is more vulnerable because of incomplete hydrovenous maturation. We analyzed infantile intracranial haemorrhage mainly caused by structural brain lesions and discuss specific aetiologies with regard to haemodynamic characteristics. SUBJECTS ...

For a variety of anatomic and physiologic reasons, premature infants, especially those of very low birth weight, are most likely to sustain an intraventricular hemorrhage (IVH) and subsequent posthemorrhagic hydrocephalus (PHH). When to initiate treatment and what that treatment should be remains controversial. This article discusses the pathophysiology and clinical ...

OBJECTIVE: Posthemorrhagic ventricular dilation (PHVD) is a complication of intraventricular hemorrhage in preterm infants and is associated with a high risk of long-term disability.
