Ventricular Shunting

Abstract We reviewed the computed tomographic findings after 1055 intracranial operations to determine the incidence of postoperative extradural hematomas. There were 11 medium and 5 large hematomas after 1055 operations (1.0%). Ten of the 16 hematomas were operated upon (10/1055, 0.9%). Four of the 10 hematomas were seen after 278 brain tumor removals (1.4%), another four after 190 aneurysmal operations (2.1%), one after 14 intracerebral hematoma removals (7.1%), and the last one after 251 ventricular shunting or drainage procedures (0.4%). In 4 of the 10 operated hematomas, sites were regional, in five sites were adjacent, and in one the site was distant. All of the five adjacent hematomas extended downward from a lower rim of the operative locus. Causes were analyzed in the three types of the hematomas. In case of the regional hematomas, the causes were incomplete hemostasis of the dura mater or the bone in all four patients, nonperformance of central stay sutures in three, systemic hypertension in one, and hypofibrinogenemia in one. In the adjacent hematomas, we could find dural separation at an edge of craniotomy in all five patients, abrupt collapse of the brain in all, ventricular dilatation in two, and systemic hypertension during immediate postoperative period in two. In one distant hematoma, ventricular dilatation and ventricular shunting procedure were themselves thought to be the causal factors.

Ventricular Shunting

Abstract A rare complication of ventriculoperitoneal shunting is presented. In this case, a moderate-sized intracerebral hemorrhage (3 to 5 cm in maximal diameter) occurred 1 week after operation for idiopathic hydrocephalus in a 43-year-old woman. The patient recovered fully without operative intervention. No other case of delayed intracerebral hemorrhage after a ventricular shunting procedure was found in a review of the literature. The presumed mechanism in the present case is delayed erosion of a cerebral blood vessel by the ventricular catheter.

Ventricular Shunting

Abstract A series of adult patients with idiopathic hydrocephalus in whom shunts were placed are presented. Preoperative diagnostic and prognostic criteria were evaluated. Findings on computed tomographic scans (significant ventricular enlargement, the absence of gyral atrophy, and the absence of sylvian fissure enlargement) and the clinical triad associated with hydrocephalus in adults (dementia, ataxia, and especially incontinence of urine) all contributed individually and in combination to the diagnosis of hydrocephalus that could be corrected by surgery. The use of radionucleotide cisternography did not add any additional information. Its use as a diagnostic or prognostic aid is, therefore, suspect. The use of high-pressure shunting systems for the initial shunting procedure is emphasized.

✓ Adult dogs were rendered hydrocephalic by the injection of kaolin into the cisterna magna. One group of dogs was sacrificed 1 month after kaolin administration, and ventriculojugular shunts were performed on the other group. Hydrocephalic dogs with shunts were sacrificed 1 day or 1 week after the shunting procedure. All dogs were perfused with formalin at physiological pressure, and the brain stem and cervical spinal cord were examined by light microscopy. Subarachnoid granulomata encompassed the superior cervical spinal cord and dependent surface of the brain stem. Rarefaction of the posterior white columns and clefts or cavities involving the gray matter posterior to the central canal and/or posterior white columns were present in the spinal cords of both hydrocephalic and shunted hydrocephalic dogs. Predominantly in the dogs with shunts, hemorrhages were noted in the spinal cord in association with the clefts or cavities. A mechanism of ischemia followed by reflow of blood is postulated to explain the hemorrhages in the spinal cords of hydrocephalic dogs with shunts.
