    Abstract:
    OBJECTIVE: To evaluate the incidence and risk factors for ICE during a PV. MATERIALS AND METHODS: Single-center retrospective analysis of 1512 consecutive patients who underwent 1854 PV procedures for osteoporotic (34 %), malignant (39.9 %) or other cause (26.1 %) of vertebral compression fractures (VCFs)/spine tumor lesions. Only thoracic or lumbar PVs were included. PVs were performed with polymethylmethacrylate (PMMA) low-viscosity bone cement under fluoroscopic guidance. Chest imaging (X-ray or CT) was performed the same day after PV in patients with high clinical suspicion of ICE. All post-procedural chest-imaging examinations were reviewed, and all ICEs were agreed upon in consensus by two radiologists. RESULTS: ICEs were detected in 72 patients (92 cement embolisms). In 86.1 % of the cases, concomitant pulmonary artery cement leakage was detected. Symptomatic ICEs were observed in six cases (8.3% of all ICEs; 0.32% of all PV procedures). No ICE led to death or permanent sequelae. Multiple levels treated during the same PV session were associated with a higher ICE rate [OR: 3.59, 95% CI: (1.98-6.51); p < 0.001]; the use of flat panel technology with a lower ICE occurrence [OR: 0.51, 95% CI: (0.32-0.83); p = 0.007]. CONCLUSION: Intracardiac cement embolism after PV has a low incidence (3.9 % in our study). Symptomatic complications related to ICE are rare (0.3%); none was responsible for clinical sequelae in our series. KEY POINTS: • The incidence of intracardiac cement embolism (ICE) during PVP is low (3.9%). • Having a high number of treated vertebrae during the same session is a significant risk factor for ICE. • Symptomatic intracardiac cement embolisms have a low incidence (8.3% of patients with ICE).
