Fondaparinux therapy in a hemodialysis patient with heparin-induced thrombocytopenia type II.

Purpose: The successful use of fondaparinux in a hemodialysis patient with heparin-induced thrombocytopenia type II (HIT II) is reported.

Summary: An 85-year-old, 68-kg Caucasian woman came to the emergency department with shortness of breath and exertional chest pain radiating to the neck. Testing revealed non-ST-segment elevation myocardial infarction, severe coronary artery disease, mitral regurgitation, left ventricular dysfunction, an ejection fraction of 25-30%, and pulmonary arterial hypertension.

Routine use of the direct thrombin inhibitor bivalirudin for off-pump coronary artery bypass grafting is safe and effective.

Anticoagulation with unfractionated heparin has been the standard of care for more than a half-century for patients undergoing cardiac surgery. The risk of heparin-induced adverse reactions dictates the need for a safe and effective alternative, particularly in off-pump coronary artery bypass (OPCAB) surgery, an approach associated with a perioperative prothrombotic condition that may negatively influence graft patency. Between March 2003 and January 2005, 243 consecutive patients underwent OPCAB with bivalirudin (0.
