From: Effect of extradural constriction on CSF flow in rat spinal cord
Surgical procedures, and white light and fluorescent imaging of ex vivo brain and spinal cord. The extradural constriction surgeries involved passing a 6-0 monofilament suture (Sut) around the spinal cord (A) and tightening the suture to visibly occlude blood flow in the posterior vein (PV; B). Exposure of the occipital membrane (OM) for injection of fluorescent tracer into the cisterna magna (C). Images of the whole spinal cord and brain under white-light and fluorescent light, with extradural constriction evident (D). Labelling: Rost: rostral; Caud: caudal; S: skull
