A pacemaker-assisted microvascular decompression for a patient with left primary facial spasm and arrhythmia: a case report

Abstract

Abstract Background Primary facial spasm accompanied by arrhythmia is a rare clinical phenomenon and has not been reported before. We describe this phenomenon and discuss its mechanism and treatment. Case presentation We herein present a rare case of a patient with left primary facial spasm and a third-degree atrioventricular block (III degree AVB), who was implanted with a temporary cardiac pacemaker to receive microvascular decompression (MVD) because of refusal of a permanent cardiac pacemaker. The symptoms of facial spasm disappeared after MVD. The temporary cardiac pacemaker was removed on the second day after surgery. Her ECG still showed the third-degree atrioventricular block after a follow-up period of 5 months. Conclusions We are the first to report a patient with facial spasm and arrhythmia who was implanted with a temporary cardiac pacemaker to receive MVD. This case report demonstrated that the concomitant presence of a III degree AVB maybe not a contraindication for MVD, and the etiology of this facial spasm was the actual vascular compression of the facial nerve entry zone that was not related to the atrioventricular block.
