summary

Cardiac bypass surgery is the best way to treat angina pectoris. It's very effective, but it's expensive. Many people are curious about how and where heart bypass surgery is performed. Now let's take a look at the process of heart bypass surgery.

What is the procedure of heart bypass surgery

First: bypass surgery, as the name suggests, is to take the patient's own blood vessels or vascular substitutes, connect the distal end of the stenotic coronary artery with the aorta, let the blood pass the stenotic part, reach the ischemic part, improve the blood supply of the myocardium, so as to relieve the symptoms of angina pectoris, improve the heart function, improve the quality of life and prolong the life of patients.

Second: under local anesthesia, percutaneous right (or left) femoral artery puncture was performed. After coronary angiography, the lesion was dilated with a special balloon catheter. The balloon catheter with stent was delivered to the lesion site. The balloon was dilated at 8 atmospheres for 30-60 seconds. The stent was implanted with high-pressure balloon. The balloon was dilated at 12-16 atmospheres for 30-60 seconds to ensure uniform stent expansion. The stent will be permanently embedded in the patient's coronary artery intima.

Third: during the operation of heart bypass, 12500u heparin sodium was injected intravenously after the femoral artery sheath was inserted. After that, 2500u heparin sodium was injected intravenously every one hour, the total amount was less than 20000u. In order to prevent coronary artery spasm, 200-300 μ g nitroglycerin was injected into the coronary artery before stenting and balloon withdrawal.

matters needing attention

Heart bypass surgery has been used for many years in China. Stents will sneak into the patient's heart and continue the function of the heart, so many people will choose to do it.
