Causes and treatment of abrupt closure
| Sr. No | Cause | Treatment |
|---|---|---|
| 01 | Dissection | 1. Stent if vessel is 2 mm or more 2. IVUS to confirm presence and extent of dissection 3. Consider GP IIb/IIIa inhibitor |
| 02 | No-reflow | 1. Confirm effective anticoagulation 2. Distal delivery of vasodilators 3. Consider GP IIb/IIIa inhibitor |
| 03 | Thrombus | 1. Thrombectomy 2. Stenting 3. GP IIb/IIIa inhibitor |
| 04 | Acute stent thrombosis | 1. 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.
