Causes and treatment of abrupt closure

Sr. NoCauseTreatment
01Dissection1. Stent if vessel is 2 mm or more 2. IVUS to confirm presence and extent of dissection 3. Consider GP IIb/IIIa inhibitor
02No-reflow1. Confirm effective anticoagulation 2. Distal delivery of vasodilators 3. Consider GP IIb/IIIa inhibitor
03Thrombus1. Thrombectomy 2. Stenting 3. GP IIb/IIIa inhibitor
04Acute stent thrombosis1. Thrombosuction 2. IVUS 3. Redilatation if underexpanded 4. Confirm effective anticoagulation 5. Optimise antiplatelet therapy—consider GPIIb/III a inhibitor
  • IVUS, intravascular ultrasound; GP, glycoprotein.
