Transient Thermal Sympathectomy as Possible Mechanism for Hypotension after Kyphoplasty: A Case Report.
Vertebroplasty and kyphoplasty are minimally invasive treatments for vertebral compression fractures. Although infrequent, both transitory and persistent adverse effects have been reported. They range from asymptomatic to severe neurological deficits that are caused directly by polymethylmethacrylate (PMMA) leakage or may be related to local or general reactions not due to PMMA leakage. Transitory hypotension after the procedure has been observed, but the characteristics and etiology of this phenomenon are not defined. ⋯ Prolonged hypotension can complicate kyphoplasty at upper lumbar levels. Two days of severe hypotension has not been described as a complication of kyphoplasty. Although the mechanism is unknown, a transient thermal sympathectomy may be the cause.
