Management of Aspirin Before PainTeq LinQ Procedure

Risk Assessment and Recommendations

For high-risk endoscopic and interventional procedures, aspirin should be discontinued at least 3 days before the procedure, as recommended by the American Society of Anesthesiologists and the European Society of Gastrointestinal Endoscopy, to minimize bleeding risk while balancing thrombotic concerns 1, 2
The irreversible effect of aspirin on platelets requires time for new platelets to be produced, with sufficient hemostatic competence typically returning after 3 days of discontinuation, according to the American Society of Anesthesiologists 1
Complete recovery of platelet function is not necessary for adequate hemostasis during procedures, explaining why a 3-day washout is generally sufficient rather than the full 7-10 day platelet lifespan, as stated by the American Society of Anesthesiologists 1

For patients at high thrombotic risk, such as those with recent coronary stent placement, acute coronary syndrome, or cerebrovascular disease, consultation with the prescribing cardiologist or neurologist is essential before stopping aspirin, as recommended by the American College of Cardiology and the European Society of Cardiology 2, 3
For patients with very high thrombotic risk, such as those with coronary stent placement within 6 weeks, consider deferring the elective procedure if possible, according to the American College of Cardiology 3
For patients with moderate to low thrombotic risk, the 3-day aspirin discontinuation is generally safe, as stated by the American College of Cardiology and the American Society of Anesthesiologists 3, 1

For patients with coronary stents or recent cardiovascular events, the decision to discontinue aspirin must involve a cardiologist, as recommended by the American College of Cardiology 2, 4
If thrombotic risk outweighs bleeding risk, consider proceeding with the procedure while continuing aspirin, with extra vigilance for bleeding complications, according to the American College of Cardiology 2
For patients on dual antiplatelet therapy, aspirin may be continued while P2Y12 inhibitors should be discontinued 5-7 days before the procedure, as recommended by the American Society of Anesthesiologists 5, 6

Resume aspirin 12-24 hours after the procedure if adequate hemostasis is achieved, as recommended by the American College of Gastroenterology 2
Advise patients about increased risk of post-procedure bleeding compared to those not on antiplatelet therapy, according to the American College of Gastroenterology 2

Most guidelines are based on moderate to low quality evidence regarding optimal timing of aspirin discontinuation, as stated by the American College of Gastroenterology 2
The 3-day discontinuation recommendation balances the bleeding risk with the thrombotic risk of prolonged discontinuation, according to the American Society of Anesthesiologists 1

Avoid bridging with heparin for aspirin discontinuation as this may increase bleeding risk without clear benefit, as recommended by the American College of Cardiology and the European Society of Cardiology 3, 8
