A Whitacre-type spinal needle does not prevent intravascular injection during cervical nerve root injections.
We present a case of intravascular injection in a 41-year-old female during cervical selective nerve root injection using a 22-gauge 3.5-inch Whitacre-type pencil-point subarachnoid needle with a curve placed at the distal tip positioned using continual live fluoroscopic guidance. After negative aspiration for blood and cerebrospinal fluid and no elicited paresthesias during the procedure, 1 mL of contrast was injected. Initial imaging at C6 captured the outline of the nerve root along with a significant amount of transient vascular runoff. This case report demonstrates that Whitacre-type spinal needles do not prevent vascular injection, and that aspiration of the needle is not a reliable sign of intravascular injection.
