A blocked bypass vessel can also be treated with stenting.
Patients with diffuse coronary artery disease need coronary artery bypass grafting. Clinically, the bridging vessel can be the internal mammary artery, but most patients need to use the saphenous vein as an alternative vessel, and stenosis of the bridging vessel can occur, which again leads to insufficient blood supply to the myocardium.
Patients with stenosis of the bridging vessel can be evaluated by coronary angiography to understand the extent and location of the stenosis, and if the stenosis is indicated for stenting, stenting can be performed to improve the blood supply to the bridging vessel.
Patients using the saphenous vein as a bridge vessel are prone to stenosis or occlusion due to vascular structural factors, at which point the site is not suitable for stent implantation.
After coronary artery bypass grafting, we should pay attention to the observation of the patient’s symptoms, regular follow-up in the hospital, and patients with stenosis should be standardized treatment under the guidance of physicians.
