Fetal Therapy for Isolated Aqueductal Stenosis

Fetal Diagn Ther. 2015;38(2):81-5. doi: 10.1159/000382015. Epub 2015 May 13.

Abstract

Aqueductal stenosis (AS) is a form of noncommunicating hydrocephalus, which causes increased intracranial pressure secondary to obstruction of the aqueduct of Sylvius. Relief of intracranial pressure in the fetus by ventriculoamniotic shunting may diminish or even prevent permanent neurologic injury. Shunting was attempted in the 1980s but was abandoned due to technical difficulties. Given the advances in prenatal diagnosis and fetal intervention over the last 3 decades, we believe that an evidence-based reevaluation of the option is timely and appropriate. The aim of this review article is to discuss the clinical significance of the diagnosis of AS, current management strategies, current diagnostic capabilities, new shunt technology, and barriers to progress. Finally, we will advance a research agenda that will provide evidence-based management recommendations.
