Compressive neuropathy of the brachial plexus and long thoracic nerve: a rare complication of heparin anticoagulation.

We present a case of a 69-year-old woman who developed brachial plexopathy and long thoracic nerve palsy secondary to compression from a hematoma while receiving heparin therapy for the treatment of a stroke. The patient was treated conservatively with discontinuation of heparin and had complete resolution of her compressive neuropathy. This is the first report of a patient with long thoracic nerve palsy with a brachial plexopathy complicating anticoagulation. We review the literature on hematoma-induced compressive neuropathies and treatment options. Our review concludes by emphasizing the importance of clinical judgment in determining the best therapeutic modality.
