Prenatal isolated mild ventriculomegaly: outcome in 167 cases

“…In a review of 366 cases of IMV, 5 97% of the children had normal development in the event of unilateral ventriculomegaly versus 89.6% in the event of bilateral enlargement. Other studies gave similar results, with more than 90% of normal children in the case of unilateral IMV 11–13,25,26 . Atrial width determines prognosis.…”

“…Fifty percent of asymmetrical and bilateral ventriculomegalies were associated with postnatal neurological disease versus 10% of symmetrical enlargement and 7.5% of unilateral enlargement. Many studies conclude that unilateral ventriculomegaly has a good prognosis, 5,12,13,25,26 but asymmetry does not appear in the published studies as a factor in a worse prognosis. The third factor is whether the enlargement is progressive (P = 0.02).…”

“…Other studies gave similar results, with more than 90% of normal children in the case of unilateral IMV. [11][12][13]25,26 Atrial width determines prognosis. Studies of ventricular size in the prognosis of IMV have shown that neurological outcome correlates closely with the degree of enlargement.…”

“…After June 1999, a specific follow-up protocol was set up in the paediatric neurology department of the hospital ( Table 2); all the medical consultations involved a formal neurological examination and developmental assessment.

The methods of psychomotor assessment were decided according to the children's age.…”

The Role of Transcranial Doppler Sonography in the Management of Pediatric Hydrocephalus

“…is considered to be a negative prognostic factor [374]. Many studies confirmed good prognosis for children with unilateral ventriculomegaly [375][376][377]. Interpretation of changes in the Doppler curve of the cerebral arteries in pediatric hydrocephalus remains to be a discussed issue.…”
