Definition of Problem

In performing noncardiac surgery on patients on anticoagulation, the major concern is when it is safe to perform surgery without increasing the risk of hemorrhage or increasing the risk of thromboembolism (eg, venous, arterial) after discontinuing treatment. In treating patients on long-term warfarin perioperatively, consider the risks of hemorrhage or thromboembolism versus the benefit from the operation. When considering noncardiac surgery, these factors and the need to weigh the risk of hemorrhage against that of thromboembolism must be analyzed on an individual patient basis. Certain procedures (eg, oncologic procedures, threats to limb or life) are easy analyses. More complex discussions must be had for such cases as hernia repair of other elective nonurgent operations.

The perioperative management for these patients can be one of the following: continue warfarin therapy, withhold warfarin therapy for a period of time before and after the procedure, or temporarily withhold warfarin therapy and also provide a "heparin bridge" during the perioperative period. Which management option to follow is primarily determined by the characteristics of the patient and by the nature of the procedure.

Patients with prosthetic heart valves pose a particular problem. Arterial thromboembolism from the heart often results in death (40% of events) or major disability (20% of events).
