Brachial plexus palsy after Nuss procedure for pectus excavatum.

Brachial plexus palsy rarely occurs after Nuss procedure for pectus excavatum. Brachial plexus palsy after surgery may be caused by nerve tension and compression related to surgical positioning. In this article, we report a 21-year-old male patient of brachial plexus palsy after Nuss procedure revealing a narrowing of the costoclavicular space from 7.60 mm to 2.83 mm and an increase to 4.51 mm after upper bar removal. Patient"s symptoms were fully recovered. Our results showed that narrowing of the costoclavicular space after Nuss procedure might trigger brachial plexus palsy and that brachial plexus palsy may not be related to surgical positioning.
