OBJECTIVE: To evaluate the feasibility and safety of percutaneous endoscopic technique in the treatment of intraspinal cement leakage after percutaneous vertebroplasty (PVP).
METHODS: Between May 2014 and March 2016, 5 patients with lower limb pain and spinal cord injury caused by intraspinal cement leakage after PVP, were treated with percutaneous endoscopic spinal decompression. Of 5 cases, 3 were male and 2 were female, aged from 65 to 83 years (mean, 74.4 years). The course of disease was 10-30 days (mean, 16.2 days). Imageological examinations confirmed the levels of cement leakage at T 12, L 1 in 3 cases, and at L 1, 2 in 2 cases; bilateral sides were involved in 1 case and unilateral side in 4 cases. Two patients had lower limb pain, whose visual analogue scale (VAS) were 8 and 7; 3 patients had lower extremities weakness, whose Japanese Orthopedic Association (JOA) 29 scores were 18, 20, and 19. According to American Spinal Injury Association (ASIA) impairment scale, neural function was rated as grade E in 2 cases and grade D in 3 cases.
RESULTS: The operation time was 55-119 minutes (mean, 85.6 minutes), and the blood loss was 30-80 mL (mean, 48 mL). CT scan and three-dimensional (3D) reconstruction at 1 day after operation showed that cement leakage was removed in all patients. Five cases were followed up 6-21 months (mean, 12 months). In 2 patients with lower limb pain, and VAS score was significantly decreased to 2 at last follow-up. In 3 patients with lower extremities weakness, the muscle strength was improved progressively, and the JOA29 scores at last follow-up were 21, 23, and 22.
CONCLUSION: Percutaneous endoscopic technique for intraspinal cement leakage after PVP is safe, effective, and feasible.
