Slit like ventricle and isolation of CSF pathway as complications of shunt procedure in child hydrocephalus, (3)

The shunt procedure in hydrocephalus in 164 chilren (under 15 years of age) was followed by a slit-like ventricle in 46 cases, an isolated fourth ventricle in 6 cases, an isolated unilateral hydrocephalus in 4 cases, and a loculated ventricle in 3 cases. The pathological conditions of the isolation of the CSF pathway were observed and confirmed by metrizamide CT cisternography and ventriculography, while the hydrodynamics of the CSF under these pathological conditions was sequentially and dynamically analyzed. There was a complication of a slit ventricle in 4 cases of an isolated fourth ventricle, in all 4 cases of an isolated unilateral hydroccephalus, and in 1 case of a loculated ventricle, and a re-dilation of the slit-like ventricle resulted in an improvement in the pathological conditions in 2 cases, 1 case, and the 1 case respectively (reversible isolation). In 2 cases of an isolated fourth ventricle, the obstruction of the aqueduct of the midbrain persisted (permanent isolation), regardless of changes in the paracelic function of the shunt tube, resulting in a double compartment; the installation of a separate shunt tube was required in both cases. Some cases of isolated fourth ventricle remained asymptomatic (asymptomatic isolated fourth ventricle), although it could be confirmed on the basis of an examination of the CSF, that the pathological conditions had been completed.
