Recurrent spinal epidural hematoma: case report.

We report the case of a man of 65 who, at 20 and 37 days from surgery of C6 corpectomy, experienced two epidural hematomas at C7-D1. We assume that the pathogenic cause of this rare disease was an overlap between three main factors: the surgical aggression of the internal anterior epidural venous plexus; a possible increase of intra-thoracic pressure due to chronic obstructive pulmonary disease; and double antiplatelet drug therapy.
