Ventricular system necklace | sterling silver The first time a neurosurgical resident places an external ventricular drain into the right lateral ventricle, the inner brain stops being abstract. Working anatomy. This 28 mm sterling silver pendant carries that same set of CSF-filled cavities, the system every neurosurgeon, neuroradiologist, and neurointensivist learns to read on imaging and access in the operating room. The Anatomy of the Ventricular System The ventricular system is a connected set of four cerebrospinal fluid cavities. The two lateral ventricles sit one in each cerebral hemisphere. The third ventricle is a midline slit between the thalami, and the fourth ventricle lies between the brainstem and cerebellum. Cerebrospinal fluid is produced by the choroid plexus at roughly 500 ml per day, circulates through the system via the foramina of Monro and the cerebral aqueduct of Sylvius, exits at the foramina of Magendie and Luschka into the subarachnoid space, and is reabsorbed by arachnoid granulations into the venous sinuses. Obstruction at any point causes hydrocephalus. The same anatomy is the route used for CSF drainage, intraventricular drug delivery, and endoscopic third ventriculostomy. Who Tends to Wear This neurosurgeons who place EVDs and manage hydrocephalus neurologists and neuroradiologists who interpret ventricular anatomy on imaging neurointensivists managing raised intracranial pressure medical students and residents who have learned the CSF circulation Most often given when a neurosurgical resident finishes training, or as a thank-you to a neurointensivist or neuroradiologist who taught the anatomy well.

Working neurosurgeons are usually the ones picking it up for themselves, or recognising it on a colleague. The ventricular system is one of the structures every neurosurgical training programme drills into trainees, because EVD placement, ventriculostomy, and shunt revision all depend on knowing this anatomy cold. A pendant of the same anatomy reads as recognition, not decoration. Neuroradiologists and neurointensivists react the same way. Why does the ventricular system get more clinical attention than other brain cavities? Because it is the only space inside the brain that neurosurgeons routinely access. The subarachnoid space is on the outside. The ventricular system is the inside, the one set of cavities a catheter can be placed into through a burr hole. CSF drainage, intraventricular antibiotics for ventriculitis, and decompression in hydrocephalus all happen through this same set of chambers. A working neurosurgical career touches them weekly. What size is the pendant and what is the return policy? 925 sterling silver, 28 mm pendant on a 45 cm sterling silver chain with a 5 cm extender. Nickel-free and hypoallergenic. Free worldwide DHL Express in 1-5 business days, with all import duties and taxes covered. 30-day “Love It or Return It” returns. Is there a gold version? Yes. The same 28 mm ventricular system pendant is available in 18K gold vermeil at the same chain length. Most often used as a milestone gift at the end of neurosurgical training, where the gold reads as recognition rather than daily wear.
