STUDY DESIGN: During vertebroplasty (VP), polymethylmethacrylate (PMMA) may leak into the posterior epidural venus plexus, provoking symptoms ranging from radicular pain to medullar compression.
OBJECTIVES: To propose and test the feasibility of a procedure (cooling system) to prevent radicular irritation caused by foraminal PMMA leakage.
SUMMARY OF BACKGROUND DATA: Foraminal leak of PMMA, as observed during VP, may lead to radiculalgia. Several mechanisms of nerve root irritation have been proposed. Considering heat or local chemical irritation has led us to treat immediately by local periradicular irrigation with a cooling liquid.
METHODS: Four consecutive patients with observed foraminal leakage were treated by local fluid injection. Immediately after observation of a foraminal leak, a 20-gauge Chiba needle was positioned to reach the foramen. Ten cubic centimeters of lidocaine (0.2%) was followed by 100-200 cc of pressurized saline perfusion within 10-20 minutes (cooling system).
RESULTS: In all patients with foraminal leakage, no radicular pain existed after application of the cooling system. No complications were observed with its use.
CONCLUSION: In presence of a foraminal leakage, the immediate application of a cooling irrigation may protect the root from injury, which is explained by the hypothesis that the main mechanism of injury may be more related to heat or chemical irritation of the nerve than compression.
