Case Study: Artery May Interfere With Cervical Radiofrequency Neurotomy

Physicians at Ohio State University Medical Center reported a patient's temporary vision loss after receiving local anesthetic for cervical radiofrequency neurotomy, according to a case study published by the American Society of Regional Anesthesia and Pain Medicine.

The case, reported at the society's 2010 annual meeting, attributed the patient's five-minute blindness to the deep (ascending) cervical artery that can occupy part of the target area for cervical RF neurotomy. The DCA also connects with the occipital artery and sometimes with the vertebral artery.

The physicians found blood in the needle after injecting their patient with 0.5 ml of 0.25 percent Bupivicaine, and warn that "even minute amounts of local anesthetic into this vessel [DCA] can produce devastating neurological complications."
