[Massive pulmonary embolism mimicking ST-elevation acute coronary syndrome successfully treated with hybrid therapy in a trauma patient receiving nadroparin: diagnostic and therapeutic dilemmas].

A case of a 48-year-old woman with a comminuted fracture of the left tibia and receiving prophylactic doses of nadroparin, with massive pulmonary embolism mimicking ST-elevation acute coronary syndrome and complicated by cardiogenic shock and cardiac arrest, is presented. Pulmonary angiography showed total right pulmonary artery occlusion. Intraarterial thrombolysis with reduced dose of alteplase (50 mg), platelet GP IIb/IIIa blockade with eptifibatide, endovascular embolus fragmentation with a pigtail rotation catheter, and rescue pulmonary balloon angioplasty were performed, after which complete recovery was achieved. On day 4 of hospitalisation the patient was transferred to the orthopaedic ward where she underwent uneventful tibial surgery.
