Summary
Complications from percutaneous vertebroplasty (PV) for spinal metastases are rare. Most cement leaks are asymptomatic, with serious complications linked to intravascular leakage.
Area of Science:
- Interventional Radiology
- Oncology
- Neurosurgery
Background:
- Spinal metastases cause significant pain and morbidity.
- Percutaneous vertebroplasty (PV) is a minimally invasive procedure to treat painful vertebral compression fractures.
- Polymethylmethacrylate (PMMA) cement is commonly used in PV procedures.
Purpose of the Study:
- To evaluate the incidence and types of complications associated with PV using PMMA cement in patients with spinal metastases.
- To identify risk factors for PV-induced complications.
Main Methods:
- Retrospective review of 159 PV procedures in 117 patients with spinal metastases.
- Evaluation of immediate imaging and 30-day clinical follow-up.
- Characterization of complications as local or systemic.
- Statistical analysis of variables associated with complications.
Main Results:
- A total of 423 cement leakages were identified, with 78.5% being vascular and 21.5% nonvascular.
- Eight patients (6.8%) experienced complications, with seven being symptomatic.
- Local complications included hematoma and radicular pain; systemic complications included pulmonary embolism.
- One patient with pulmonary embolism died.
- Intravascular leakage was significantly associated with pulmonary embolism.
Conclusions:
- Percutaneous vertebroplasty (PV) for spinal metastases is associated with a low rate of serious complications.
- Most cement leakages are asymptomatic and do not lead to adverse events.
- Systemic complications are primarily linked to intravascular cement migration.
- Local complications may result from cement irritation, compression, ischemia, or needle trauma.
