  • Title: Ultrasonographic evaluation of infantile hydrocephalus before and after shunting. A study in 20 children.
    Author: Machado HR, Machado JC, Contrera JD, Assirati JA, Martelli N, Colli BO.
    Journal: Childs Nerv Syst; 1985; 1(6):341-5. PubMed ID: 3914356.
    Abstract:
    The authors present the results of a prospective study of 20 children with congenital or acquired hydrocephalus of nontumoral etiology and submitted to ventriculo- (or cyst-) peritoneal shunting with valve. The diagnosis was established by B-mode or real-time brain sonography, in association with another neuroradiological procedure (computed tomography, ventriculography with air or Dimer-X, cerebral angiography). Among the proposed measurements (cortical thickness, lateral ventricle height, III ventricle width and ventricular ratio) for pre- and postoperative comparison, the cortical thickness and the lateral ventricle height were the ones that changed significantly when analyzed by sonography. The routine use of brain sonography allowed the visualization of the ventricular catheter position and the diagnosis of complications, such as subdural collection, progressive enlargement of cysts, isolated IV ventricle, etc, even before symptoms arise. The authors conclude that sonography is easily performed, inexpensive and innocuous, and should be used routinely during the follow-up of children with hydrocephalus.
