Re-blockage after bypass is treated with medication, re-bypass surgery or stent placement depending on the blockage.
For most of the patients with reoccurring myocardial ischemia after bypass surgery, conservative treatment with medication is generally used, which can achieve certain results. If drug-refractory angina occurs, further treatment is required under the joint guidance of cardiologists and cardiac surgeons.
1. Re-occurrence of blockage after bypass: if a stent can be put into the bypassed vessel or if a stent cannot be put into the bypassed vessel, it is necessary to undergo cardiac bypass surgery again.
2. New onset of vascular blockage
(1) Stent surgery: first of all, according to the degree of vascular blockage, stent surgery can be chosen to restore the blocked blood vessels to recirculate and restore the blood perfusion of the heart. After the surgery, antiplatelet drugs should be taken according to the doctor’s instructions, such as aspirin, clopidogrel, and lipid-lowering drugs such as nolvastatin should be used when necessary.
(2) Bypass surgery: If the blood vessel is seriously blocked and stenting is not possible, cardiac bypass surgery is needed again, and anti-platelet drugs such as aspirin should be used after the surgery.
If the above symptoms occur, timely treatment is needed, consult a professional doctor for standardized treatment, and follow the doctor’s instructions for medication.
