CARDIAC-ARRHYTHMIAS FROM A MALPOSITIONED GREENFIELD FILTER IN A TRAUMATIC QUADRIPLEGIC

A case study is presented of premature Greenfield filter discharge with intracardiac migration and resulting life-threatening arrhythmias. These arrhythmias also interfered with the patient's transition from ventilatory support via orotracheal intubation to noninvasive positive airway pressure ventilatory support methods. The patient's arrhythmias were controlled by a demand cardiac pacemaker and cardiac glycoside therapy. No anticoagulants were used. She had no further filter migration nor significant complications for 16 months after hospital discharge.
