title: [Persistent neurological deficit of the upper extremity after a shoulder operation under general anesthesia combined with a preoperatively placed interscalene catheter].
abstract: For correction of a shoulder instability (Bankart's operation) in a 33-year-old woman, a combined regional and general anaesthesia was chosen. An interscalene catheter to block the brachial plexus was placed preoperatively without complication. The following day this resulted in an upper extremity almost without motor function and with complete hypoesthesia of the dermatomes C5-C7. Surgical exploration of the plexus was performed 41/2 months later. Stimulation of the three truncs of the brachial plexus was possible and showed electrophysiological signs of recovery of distal parts of the plexus. After 2 years no clinical corresponding recovery could be observed. Despite all investigations (electroneuromyography, evoked potentials, etc.) no clear etiology could be established to explain this adverse outcome.
