Antiplatelet therapy in the perioperative period.
Antiplatelet drugs are the cornerstone treatment in the secondary prevention of arterial thrombosis. Until recently, their intake was interrupted in the perioperative period because of fear for bleeding, but new insights have challenged this old habit: In patients at high risk for atherothrombotic events who need to undergo surgery or an invasive procedure, the risk for bleeding complications because of a treatment with low-dose acetylsalicylic acid (LD ASA) needs to be balanced against the risk of atherothrombotic events after treatment discontinuation. For patients at high risk of atherothrombotic complications recent guidelines do no longer advocate to interrupt LD ASA routinely. However, the likelihood of bleeding versus atherothrombotic complications should be considered on a case-by-case basis. When continued perioperatively, the bleeding risk associated with thienopyridines (ticlopidine, clopidogrel and prasugrel) is higher than that of LD ASA. It is recommended to stop their intake 1 week before the surgical intervention, except in patients with (recent) coronary stenting.
