About this trial

This is an interventional treatment trial for Hydrocephalus

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Adult patients (age 18 or older) with communicating hydrocephalus, who have risk factors for complications following shunt surgery. Risk factors include loculated hydrocephalus (i.e., imaging evidence that the ventricles of the brain do not communicate with each other, in the setting of known communicating hydrocephalus); prior episodes of ventriculitis and/or shunt infection; subdural hematoma associated with shunt placement; inability to place a distal catheter in the peritoneal cavity due to scarring or prior infection; and multiple prior episodes of shunt failure.
  • In patients with communicating hydrocephalus who have significantly increased lateral and third ventricular size and normal fourth ventricular size, an endoscopic third ventriculostomy will be performed in conjunction with the choroid plexus cauterization, provided that communicating hydrocephalus is thought to be present, based on either the history (for example, past meningitis or other infectious or inflammatory disease, or history of communicating hydrocephalus without disproportion of the ventricles in the past; or imaging findings, such as patency of the foramina of Magendie and Luschka).

Exclusion Criteria:

  • Exclusion criteria include patients who have non-communicating hydrocephalus; patients who are undergoing emergency surgery because of rapid decline in neurologic condition; and patients with medical conditions such as coagulopathy or severe cardiac conditions, that preclude neurosurgical intervention.
  • In the case of adults unable to consent, informed consent will be obtained from appointed health care proxies. Minors, pregnant women, and prisoners will be excluded from the study.

5. Study Description

Brief Summary
The purpose of this study is to determine whether endoscopic choroid plexus coagulation is safe in adult patients with communicating hydrocephalus and risk factors for complications from the standard surgical treatment. It may also help determine whether the endoscopic choroid plexus coagulation is effective in treating your communicating hydrocephalus. The Investigators hope that this research will allow us to place fewer shunts in patients with conditions similar to yours, avoiding complications.

Arm Title
Choroid Plexus Coagulation
Arm Type
Experimental
Arm Description
Patients with communicating hydrocephalus will be treated with endoscopic choroid plexus coagulation.
Intervention Type
Procedure
Intervention Name(s)
endoscopic choroid plexus coagulation
Intervention Description
A burr hole will be made over the frontal lobe of the brain. An endoscope will be introduced into the ventricle of the brain and the choroid plexus coagulated with an electrocautery device. The septum pellucidum separating the right and left lateral ventricles will be opened, and the choroid plexus on the opposite side coagulated as well.
Primary Outcome Measure Information:

Occurrence of post-operative complications
Description
Complications will be defined as new neurologic deficits after surgery; hemorrhage or stroke on postoperative imaging studies; or other perioperative complications.
Time Frame
30 days
Secondary Outcome Measure Information:
Title
Shunt independence
Description
Shunt independence is defined as the patient surviving with no need for ventricular shunt placement
Time Frame
