A technique involving the combined use of Amipaque (metrizamide) and computerized tomography scanning is described for the evaluation of ventriculoperitoneal and ventriculoureteral shunt function. The results of three illustrative cases from a series of nine patients are given. In five patients, the technique demonstrated obstruction that was later confirmed at surgery. In the other four patients, it showed patency in the shunt system, and no surgery was performed, thereby obviating unnecessary…

Metrizamide shuntography for evaluation of shunt malfunction in hydrocephalus.

Ventricular shunts were evaluated by a shuntographic technique using metrizamide for the contrast material and delayed spot films and computed tomography (CT) to evaluate shunt function. Thirty

Evaluation of CSF shunt function: value of functional examination with contrast material.

Functional positive-contrast shuntography allows the clinician to differentiate between physiologic and anatomic shunt failure and between shunt Failure and normal shunt function and allows for precise localization of the shunt obstruction in anatomicShunt failure.



Studies of the third circulation. Amipaque CT cisternography and ventriculography.

The functional integrity of ventricular shunts can be appraised using the ventricular persistance of Amipaque as a primary criterion and the morphological and physiological characteristics of intracranial cysts are accurately defined.

The Use of the Valvogram for the Detection of Shunt Blockage in Hydrocephalic Children

Valvography is a simple, safe, rapid, easily interpreted technique for the investigation of possible blockage of the distal end of the shunt system containing a Spitz‐Holter valve and has proved to be a valuable addition to the practical management of shunt‐dependent children.

Cerebrospinal fluid scanning and ventricular shunts.

The routine lumbar injection of 131I human serum albumin (RISA) may be used instead of the more difficult and potentially dangerous intraventricular, cisternal, or direct shunt injections to

Valvulography. A test for patency of holter valve shunts.

Radioactive material, such as iodinated I131 serum albumin (Risa 131), has been utilized 1-6 to study cerebrospinal flow through shunt systems.

A simple test of shunt function: the shuntgram. Technical note.

An x-ray film method to ascertain the function of ventricular shunts in hydrocephalic patients is presented and results in 131 determinations are presented.

Radionuclide assessment of cerebrospinal fluid shunt function in children.

The technique is a reliable method for deter mining shunt patency and semi-quantitating CSF shunt flow and may also provide a means of identifying patients with “arrested―hydroce phalus.

Determination of cerebrospinal fluid shunt function with water-soluble contrast medium.

Computerized tomography has decreased the number of the total revisions complete changes of shunting systems, eliminating some unnecessary changes of normally functioning catheters.


Tests of the pa t ency of the valve sys tem i n vivo have been under taken, using radioact ive iodinated serum albumin (RISA) and RISA, to determine if a ventr iculovascular shun t is funct ioning, there are occasions when there is some doub t as to its function.

Ultrasound determination of cerebrospinal fluid shunt patency. Technical note.

A technique employing a Doppler ultrasound flowmeter in determining cerebrospinal fluid shunt patency is described. The technique has proven to be a valuable aid in the elevaluation of the patient in
