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.
