Early research carried out on its use in microvascular surgery showed promising results in preventing thrombosis and improving flap survival rates, however interest in its use in microsurgery has diminished in recent years. In this report we describe its use in successful free flap salvage and discuss its role in microsurgery.Keywords: Epoprostenol, flap salvage, vasospasm, microsurgery, thrombosis
