Fluoroscopically guided transforaminal epidural catheterization of the ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic, progressive, autoimmune collagen tissue disease characterized by inflammation and lower back pain. General anesthesia may pose a high risk in the AS due to intubation difficulty, as well as affected respiratory and cardiovascular organs. In cases of involvement of the vertebrae, neuraxial anesthesia may be difficult or even impossible. In this article, we discuss a case of AS that received a successful an epidural catheter was placed using a transforaminal route under C-arm fluoroscopy guidance for total hip replacement surgery, which was difficult due to intubation and an interlaminar neuraxial anesthesia.
