Peri‐operative brachial plexus injury following self‐positioning for stereotactic radiofrequency ablation

Abstract

A 71-year-old woman with a known accessory cervical rib and distinct scoliosis was scheduled for elective, percutaneous stereotactic radiofrequency ablation of a non-resectable intrahepatic cholangiocellular carcinoma. Patient positioning and fixation using a Bluebag fixation system (Medical Intelligence, Schwabmünchen, Germany) and a dedicated adjustable armrest were customised in the patient while awake. In order to provide safe conditions for mask ventilation and tracheal intubation, the patient was returned to standard supine positioning without changing the position of the armrest. Following the induction of general anaesthesia, the patient's arm was returned to the previously defined position. Upon completion of the procedure and emergence from anaesthesia, the patient immediately reported symptoms of severe brachial plexus damage. Therefore, we suggest that awake positioning according to current recommendations does not completely preclude the possibility of neurologic injury.
