A needle is put into the reservoir and a small amount of fluid that surrounds your brain and spinal cord is removed. The fluid sample may be sent to a lab for testing. The chemotherapy is then injected slowly into the reservoir; and the needle is removed.
What is the purpose of intrathecal chemotherapy?
Intrathecal (IT) chemotherapy is used to treat cancers that have entered into the CSF. When a cancer has gotten into the CSF, it may be called CNS (central nervous system) involvement.
What is a Rickman Reservoir?
This device is used to deliver ventricular (intra-thecal) chemotherapy via a small reservoir. It is usually sited on the anterior aspect of the head.
Can Ommaya reservoir be removed?
Ommaya reservoirs usually aren't removed unless they cause problems, such as an infection. Though at some point in the future you may no longer need your Ommaya reservoir, the process to remove it carries the same risks as the process to implant it. Generally, removing it isn't worth the risk.
How does medulloblastoma spread?
Medulloblastoma tends to spread through cerebrospinal fluid (CSF) — the fluid that surrounds and protects your brain and spinal cord — to other areas around the brain and spinal cord. This tumor rarely spreads to other areas of the body.
What is a VP shunt for hydrocephalus?
A ventriculoperitoneal (VP) shunt is a cerebral shunt that drains excess cerebrospinal fluid (CSF) when there is an obstruction in the normal outflow or there is a decreased absorption of the fluid. Cerebral shunts are used to treat hydrocephalus.

An Ommaya reservoir is a quarter-sized, soft, plastic, dome-shaped device that is placed under your scalp. It’s connected to a catheter (thin, flexible tube) that’s placed in one of the ventricles in your brain (see Figures 1 and 2).
How long after ommaya surgery can you play sports?
For at least 6 weeks after your Ommaya reservoir placement surgery, don’t play any contact sports (such as football, boxing, or wrestling). This gives your incision (surgical cut) time to heal. Talk with your neurosurgeon about when you can play contact sports again. Remember to wear a helmet, if needed.
How to take out CSF?
Your healthcare provider will take out a small amount of CSF through a syringe that’s attached to the tubing. The CSF may be sent to the lab to check for cancer cells or infection. If you’re also getting medication during the tap, some of the CSF may be saved in the syringe to be used as a “flush” (see step 4).

Can an MRI be performed on an Ommaya catheter?
In certain cases, the reservoir may not be readily collecting fluid. If a placement problem is suspected, an MRI scan will be performed to obtain a clear view of the Ommaya reservoir. If the reservoir or catheter is found to be out of place, a follow-up procedure may be necessary to reposition it.
Is Ommaya good for brain cancer?
The Ommaya reserv oir can be a particularly effective method of treatment for certain types of brain cancer. It delivers the chemotherapy directly to the cerebrospinal fluid to attack the malignant cells in the area. This enables the medication to bypass the blood-brain barrier-a system of blood vessels that surround the brain in order ...

What is an ommaya reservoir?
Ommaya reservoir is a valuable neurosurgical tool to deliver regular intraventricular therapy and sample the cerebrospinal fluid (CSF) without the need for serial lumbar punctures [1-4]. Since its first description in 1963, multiple papers have been published about techniques for the insertion of Ommaya reservoirs using free-hand, frame-based and image-guided methods, all of which have demonstrated success [2-4]. Improper catheter positioning and poor reservoir placement can lead to neurological complications, nonfunctioning reservoirs and the need for reoperation to reposition [2,5]. Postoperative infection, typically with gram-positive skin organisms, occurs in 5%-8% of patients and stratifies into infections occurring around the time of placement, and delayed infections, typically after recent access of the reservoir [5,6]. With the increasing prevalence of precision-based medicine, including immunotherapy and small molecule inhibitors, cancer patients are living longer and more patients are surviving with late-stage leptomeningeal dissemination, increasing the need for effective drug delivery to the CSF [7-10]. Here, we document our technique for image-guided insertion of Ommaya reservoirs and review our results using this technique.
What is the procedure for ommaya?
We suggest that image guidance should be used to optimize accuracy in placement, preassembly of the reservoir and catheter should be used with a stylet to minimize risk of clogging and recessing of the reservoir to produce the best aesthetic result.
What complications can occur after ommaya placement?
This technical note describes the technique developed by the senior author for elective insertion of Ommaya reservoirs. Postoperative complications after Ommaya placement, such as clogging, poor placement or infection, may require revision surgery, which can delay life-prolonging chemotherapy while the patient goes through the additional surgery and recovery.
What is a preoperative MRI?
Preoperative MRI scans of brain with and without contrast were performed to document size of the ventricular system , exclude parenchymal lesions along the path of the proposed trajectory and provide a volumetric study for use with the image-guided neuronavigation system. Fiducials are not required for patients with smooth skin that lacked wrinkles. Prior to surgery, we plan an ideal trajectory using the neuronavigation software. Using coronal images, we measure the distance from the middle of the diploic space to the base of the frontal horn near the foramen of Monro to measure the expected catheter length (Figure 1 ). The middle of the diploic space is selected to account for the thickness of the Ommaya reservoir and the effect of recessing the reservoir (described below).
What is an Ommaya reservoir?
An Ommaya reservoir is mainly a plastic-based drug delivery system characterized as an intraventricular catheter system that consist s of a catheter in an adjacent ventricle further attached to a tank which is inserted under the scalp area.
What happens after a surgical placement?
After the accurate placement, the patient may feel the presence of it at the back of the head in the form of a small bump. After the placement procedure is completed, the patient is advised to keep the area dry and clean until the removal of staples or stitches to remove the possibility of any infection.
Is it safe to remove Ommaya reservoirs?
Ommaya Reservoir Removal. The removal of Ommaya reservoirs is generally not considered in the practice as its existence does not present any kind of risks. But the removal of this instrument from the brain comes out with the same risks and complications that were posed at the time of insertion.
Can you vomit after a syringe?
Nausea or vomiting after the procedure. In these cases, patients are recommended to lie down for the sake of rest after the procedure is completed. After the re duction in the side effects, patients are free ly allowed to get back to their normal routines .
Is Ommaya safe to use?
Generally; the Ommaya reservoirs are safe to carry out among patients but the insertion of this device may bring some complications with it. These are very similar to the risks faced during any other surgical procedure.
