Case ReportsTransient hyponatriemia complicated by seizures after endoscopic third ventriculostomy.
We present an infant who underwent endoscopic third ventriculostomy due to symptomatic hydrocephalus secondary to aqueductal stenosis. This is the first reported case of inappropriate secretion of antidiuretic hormone complicated by hyponatriemia and seizures following endoscopic surgery. The possibility of such a neuroendoscopic complication should alert neurosurgeons and close observation of serum electrolytes is highly recommended in the acute postoperative period, particularly in infants.

We described our experience of three cases treated with endoscopic evacuation of intraventricular hematoma and third ventriculostomy for a tight intraventricular hematoma associated with intracerebral hemorrhage. A steerable endoscope was introduced into the anterior horn of the lateral ventricle contralaterally to the intracerebral hemorrhage, through a 14 Fr. peel-away sheath. First, the hematoma in the lateral ventricle contralateral to the hemorrhage was evacuated by direct aspiration using a syringe connected to the operative channel of the endoscope, and evacuation of the hematoma was subsequently carried on the third ventricle, aqueduct and the fourth ventricle. ⋯ Finally, the procedure was completed with septostomy and evacuation of the hematoma in the lateral ventricle ipsilateral to the hemorrhage. Sufficient evacuation of the hematoma was obtained in all cases and no major complications were encountered. We conclude that for patients with intraventricular hematoma associated with intracerebral hemorrhage endoscopic evacuation of intraventricular hematoma brings about sufficient removal of hematoma, reduction of hospitalization time and prevention of subsequent hydrocephalus.

This is a retrospective study to identify risk factors for failure in the treatment of obstructive hydrocephalus with endoscopic third ventriculostomy (ETV). ⋯ The risk of failure increases with intracerebral infection, likely because of obliteration of cerebrospinal fluid pathways.

Endoscopic management of cysticercal cysts within the lateral and third ventricles.
In this report the authors review their 3-year experience with the endoscopic management of patients with hydrocephalus who harbored cysticercal cysts within the third and lateral ventricles. The management plan was to utilize an endoscopic approach to remove the cysts and to incorporate techniques useful in treating obstructive hydrocephalus. The ultimate goals were to avoid having to place a complication-prone cerebrospinal fluid shunt and to eliminate the risk of complications related to cyst degeneration. ⋯ The endoscopic removal of third and lateral ventricle cysticercal cysts, combined with a third ventriculostomy or septum pellucidotomy in selected cases, is an effective treatment in patients with hydrocephalus and should be considered the primary treatment for this condition.

Clinical Trial
How effective is endoscopic third ventriculostomy in treating adult hydrocephalus caused by primary aqueductal stenosis?
To evaluate the long-term efficacy of third ventriculostomies for adult patients with hydrocephalus caused by primary aqueductal stenosis. ⋯ In our experience, the long-term effectiveness of ETVs for adult patients with noncommunicating hydrocephalus was sufficient in only 50% of the cases. One-third of the patients exhibited temporary improvements, lasting 1 to 12 months (average duration, 5 mo) after the ETVs, and then demonstrated deterioration to even worse clinical conditions, despite patent ventriculostomies. All patients who did not exhibit permanent improvements after the ETVs benefited from shunt surgery. Efforts should be made to establish methods for the selection of patients for ETV or ventriculoperitoneal shunt surgery.
