[Management of high thrombus burden in primary PCI]. / Gestion des charges thrombotiques importantes en angioplastie primaire.

A large thrombus burden is not uncommon in primary percutaneous coronary intervention, and is associated with more frequent complications. The role of intracoronary thrombolysis and glycoprotein IIb/IIIa inhibitors in the management of a large thrombus burden is discussed. The use of thromboaspiration must follow a particular logic and used with rigorous manipulations; the capacities of the protective filters are often exceeded. Stents dedicated to thrombus management can be used. Interest and limits of these stents are developed. Direct stenting should be encouraged, and delayed stenting probably considered for the most important thrombotic burden despite "negative" results in studies.
