    "I told you that the patient had four-vessel disease."

    ¡°They should take more than just the internal mammary artery.¡±

    The selection of grafted blood vessels has been introduced in detail earlier, mainly the internal mammary artery and the great saphenous vein. If it is not enough, the right gastroepiploic artery, radial artery, superior epigastric artery, etc. can be used.

    The first criterion for selecting vascular materials is that the diameter of the transplanted blood vessel should be commensurate with that of the target blood vessel, so that it can be well connected and maintain smooth and smooth blood flow after transplantation. The diameter ratio is usually one to one to two to one.  Secondly, it is necessary to ensure the patency of the transplanted blood vessels. The transplanted blood vessels should be detected in advance before the operation. During the operation, the doctor will repeatedly determine the blood flow. Therefore, there are requirements for the thickness of the grafted blood vessel wall. You cannot always choose a transplant with thickened roots

    Other problems include how to transplant the same blood vessel material to the target blood vessel.  As mentioned before, how to prune the organ transplant is most beneficial.

    The full name of the internal mammary artery is the internal mammary artery, so it is called the internal mammary artery and the internal thoracic artery. Its anatomical location is within the chest, close to the heart.

    The internal mammary artery is harvested. Its location is close to the heart, so there is no need to rush it. It can be placed at the back and performed together with the heart surgery.  Therefore, the internal mammary artery harvesting and transplantation are different from the great saphenous vein.

    The location of the great saphenous vein is relatively far from the heart, so doctors need to make preparations before harvesting it.

    In this operation, it is of course necessary to remove the great saphenous vein first, which should be the first technical difficulty in the current operation.

    Great saphenous vein harvesting is a very mature and popular operation in the surgical community, because it is a vascular material that surgeons love very much, and it is not limited to coronary artery bypass grafting.

    In the eyes of doctors, the great saphenous vein has the advantages of being straight, long, and easy to access. In addition, its blood vessel diameter is commensurate with many target blood vessels that require blood vessel transplantation, making it a naturally good material.

    Because it is a vein, its main function is to carry out blood return. Unlike arteries, which supply blood to nourish human tissues and organs, it is not that important to the human body if it is taken away.

    For example, clinically common varicose veins of the lower limbs are usually related to the great saphenous vein. In one type of surgery, high-level ligation of the great saphenous vein is directly removed without causing any problems.

    How is the great saphenous vein obtained?

    In the past, surgery before the advent of minimally invasive technology required major incisions.

    Without the assistance of minimally invasive surgical tools, it is impossible for surgeons to operate blindly. They can only cut the skin and muscles layer by layer like the steps of peeling off blood vessels in the anatomy class to expose the blood vessels hidden deep in the human body, such as underground water pipes.

    Such a surgical procedure means that the length of the surgical incision must be as long as the doctor needs to transplant the blood vessel.

    How long is the great saphenous vein?  From thigh to calf.

    Theoretically, if the doctor wants to obtain a long section of the great saphenous vein, it is possible, but in practice, a traditional surgical incision is used to cut from the thigh to the calf.  Think about a long scar from thigh to calf. Not to mention the ugly scar, such a major surgery will definitely bring sequelae.  Various radical surgical incisions will inevitably damage small nerves even if they do not damage large nerves.

    , long-term pain and dull pain are inevitable for patients.  It shows that minimally invasive technology is good, but not all surgeons can master it, and it is very expensive, and poor patients cannot afford it.  By analogy, if you don't care about money, you can do it directly without taking the patient's own blood vessels.

    Get an artificial blood vessel.  Artificial blood vessels are of course more expensive.

    In medicine, poverty itself is really a ¡°disease¡±.  Returning to the current case, there is currently no artificial blood vessel available for coronary artery bypass grafting.  (Remember the website address: www.hlnovel.com
