Successful neuraxial blockade under lumbar X-ray guidance in patients with ankylosing spondylitis: A series of 3 cases

Ankylosing spondylitis poses several anesthetic challenges ranging from difficult airway to neuraxial blockade. Limited cervical spine mobility, restricted opening of the temporomandibular joint, and cardiorespiratory compromise makes anesthesia preferred technique in these patients. However due ossification interspinous ligament ligamentum flavum, also syndesmophytes between adjacent vertebrae, its own set challenges. We present a series 3 cases which preoperative lumbosacral X-ray fluoroscopic guidance operation theater allowed for an easy more effective ankylosing patients posted transurethral resection prostate.
