EVOH (Onyx) also has weak sclerosant Homes and functions via polymerization. It can be an elastic copolymer (EVOH copolymer), dissolved in dimethyl-sulfoxide (DMSO). It's cohesive Qualities which prevents fragmentation from the injected Solid and reduce the chances of using a catheter adhere. It hardens from the surface to inside, enabling deep penetration from a gentle press in the syringe, like lava. It will eventually journey to The trail of the very least resistance allowing for a significantly better Handle. Injection amount needs to be gradual and managed as vasospasm can ensue if injected much too vigorously.
