How to open heart bypass

summary

Heart disease is a serious disease, which will threaten the lives of patients. A colleague who had heart disease underwent heart bypass surgery. Now let's introduce how to open the chest for heart bypass?

How to open heart bypass

First, preoperative preparation, including disinfection, incision, thoracotomy and other processes. The surgeon disinfected the position of the knife edge. After skin incision, use electric scalpel to gradually separate subcutaneous tissue, open sternum, need to use electric saw. Carefully open the pericardium with an electric scalpel. After cutting the pericardium, the heart appears, surrounded by a yellow layer of fat. Heart bypass surgery is a kind of delicate surgery, but also a kind of dangerous surgery, and each operation link is particularly delicate.

Secondly, the process of blood vessel "bridging". The "bridging" used in bypass surgery is divided into arterial bridge and venous bridge, which are taken from different parts of the patient's body. The great saphenous vein on the leg is rich in blood vessels, and the removal of one does not affect the overall function, so the "bridge" blood vessels are mostly taken from here. The first step is to cut the skin outside the blood vessels. After cutting along the outside of the vessel, the vessel is exposed. In the process of vascular dissection, we need to find and peel off the surrounding branches and small vessels one by one, and do a good job of ligation on both sides of the incision. In the stripping process, a nerve (at the end of the thread) and a blood vessel are mixed together. In order to keep this nerve, we can see the surgeons deal with it bit by bit. Just like other craftsmen in our life, surgeons use their own skills and patience to make more efforts to get a nerve from patients, and these patients do it without their knowledge. 　

Finally, it has something to do with "no touch" technology. Try to avoid the stimulation of blood vessels by instruments and protect blood vessels, which is conducive to the long-term patency of "bridge", so doctors will be more careful. After the dissection is completed, it is first cut from the distal end. The incision was connected with the needle and injected with normal saline to fill the blood vessels for examination. After filling the blood vessels, the surface of fat and other tissues exposed, surgeons one by one to remove. All the collateral vessels should be ligated and checked again and again to prevent blood leakage. After the "bridge" blood vessel is taken out, the knife edge needs to be sutured. The suture is complete.

matters needing attention

After heart bypass surgery, patients need to take care of their body, especially in peacetime to pay attention to daily living habits and diet, and the emotional stability of patients with heart disease is particularly important.
