However, the most preferred access route to the subarachnoid space in rats is the cisterna magna, involving a direct puncture either through the skin or following surgical preparation (Pegg et al., 2010). All these surgical approaches have advantages and disadvantages.

Therefore, a modified double hemorrhage model of cisterna magna has been developed in rat recently. We describe here step by step the surgical technique to induce double SAH and compare the degree of vasospasm with other cisterna magna rat models using histological assessment of the diameter and cross-sectional area of the basilar arter

S100 b and daily to ensure security of the Rodent Cisterna Magna Cannula (RCMC). Incision wound clips should be removed 7-10 days after surgery. Surgical Summary The animal is placed in the stereotaxic apparatus and 2-3 anchoring screws are mounted on the skull. A hole is drilled in the occipital crest for receiving the cannula.

The cisterna magna (or cerebellomedullaris cistern) is one of three principal openings in the subarachnoid space between the arachnoid and pia mater layers of the meninges surrounding the brain. The openings are collectively referred to as the subarachnoid cisterns.The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata.

CSF collection apparatus was constructed using 1 mL syringe, silicone tubing, 21G disposable needle and water. The cisterna magna is located between the cerebellum and the dorsal surface of the medulla oblongata. Cerebrospinal fluid produced in the fourth ventricle drains into the cisterna magna via the lateral apertures and median aperture.

A hole is drilled in the occipital crest for receiving the cannula. The RCMC is Cisternal Injection Procedure - Once the rat is in the stereotactic frame with head positioned at 90 degrees to horizontal, the cisterna magna is aligned with the intermeatal line (external auditory canal) This same procedure is repeated 24 hours later (Day 2) by re-opening the tail incision. Of these options, the cisterna magna is most favorable as it offers a route of entry that does not involve craniotomy. Herein we describe the cisterna magna (CM) injection procedure carried out in rats, essential for studying glymphatic influx and efflux dynamics.
