If there is a reflux of onyx within the catheter, it is usually recommended to stop the injection for one to two minutes to create a good plug round the catheter and resume the injection to thrust The brand new onyx ahead (quit-and-go method).

It has cohesive properties which stops fragmentation on the injected Forged and reduce the likelihood of getting a catheter adhere. It hardens from the surface to inside, enabling deep penetration from a delicate press from the syringe, like lava. It is going to journey to the path of minimum resistance letting a much better Handle. Injection level has to be slow and controlled as vasospasm can ensue if injected also vigorously. The speed of injection should be involving 0.one and 0.
