During the first 30-50 seconds after mixing the glue is thin but then becomes pasty. The acrylic cement has to be injected during its pasty polymerization phase to prevent distal venous migration. Two to eight milliliters of acrylic glue are injected using a pressure syringe (OptiMed Cemento Set) to facilitate the injection of this viscous mixture. At this stage, the intervention has to be performed quickly because the glue begins to thicken approx. after three minutes and any further injections become impossible. |
