What is revascularization?
Revascularization is a restoration or improvement of blood supply. A number of techniques can be used to revascularize the organ or body area due to injury, illness or other problems that interrupt blood supply. This procedure can be performed by a vascular surgeon or a cardiotorack surgeon in the operating room or clinic mounted on revascularization procedures.
Blood carries oxygen and vital nutrients. When blood supply is interrupted, it can cause the death of organs and tissues. Some things that may cause blood supply disruption include gangrene, blockages in blood vessels and severe injuries. Using Doppler ultrasound and other medical imaging studies, the doctor can identify an area where blood does not flow and learn more about why.
One option is to remove blockage. Medicines can be used to break blood clots and objects, such as stents, can be inserted to expand the blood vessels that are reduced or blocked. It uses existing vasculature for Vránaappreciates blood into the area.
Sometimes, however, the vessels are too badly damaged to make it option. In these cases it is necessary to replace grafts. Another way to manipulate revascularization is to install a bypass, skipping over a damaged or clogged area of the blood vessel to provide a new path for the blood that can be used.
The patient who is a candidate for revascularization is carefully examined to determine the extent of blood supply and the basic cause. In addition to performing physical examination in the patient, the surgeon can order a number of diagnostic tests. Patients are also evaluated to risk factors that could eliminate certain treatments such as specific drugs or surgery. The aim is to find a safe and efficient method for revascularization of the area of concerns and to solve the problem of supplying blood without exposing the patient the risk of complication.
Revascularization surgery canE with local anesthesia and seating or under general anesthesia depending on the nature of the case. One example of revascularization surgery is the surgery of the coronary artery, where the graft is used to circumvent blocked or fragile coronary artery to treat blood failure. Another form of surgery involving the heart is to revascularize transmyocard, treatment used in some patients with angina, which involves creating small channels in the heart with laser to improve blood flow.
