What is the renal angiography?
Renal angiography is a diagnostic imaging test that is carried out to control symptoms of abnormalities of blood vessels in the kidneys. The test includes injection of a specialized type of dye to the renal artery and then X -rays of the abdomen. Dispersion of the blood vessel dye occurs on the X -ray beam and doctors can visualize the type and amount of damage. Renal angiography is commonly used to identify narrow blood vessels, rupture, tumors and several other types of kidney problems. The staff of the operating room first shake and wash part of the skin above the weakness and give the patient either a localized or a general anesthetic. With the help of X -ray images in real time, the hollow needle is inserted into the artery and the thin conductor is made with a needle. The radiologist then removes the needle and moves the plastic tube called the catheter over the conductor. The contrastmine, the chemical dye that is displayed on the X -rays, is drawn by the catheter to the artery. Several X -ray images are taken before removing the catheter. RThe adiologist puts pressure on the weakness to stop the bleeding and dressing points. The whole procedure of kidney angiography can usually be performed in less than one hour.
After renal angiography, radiologist and other specialists can review X -ray findings. The contrast medium is well displayed on X -rays, allowing doctors to clearly monitor the flow of the kidneys. On the basis of the dye path, any blood clots, unusual matter or narrow arteries can be easily identified. Renal angiography results help doctors to determine the most appropriate treatment.
In many cases, renal angiography suggests that surgical repair is needed. Surgeons can try to have a excise duty, repair the weakened walls of the blood vessels or replace a part of the severely damaged tissue. A common procedure called angioplasty involves inserting a synthetic stent into a narrow vessel to open and allow the blood flow more freely.
Renal angiography is a valuable tool that can significantly improve the confidence of doctors in diagnosis and ensure that the patient receives the best possible treatment. In addition, the radiologist can regularly perform angiography during the recovery phase to ensure that the treatment is successful. The emerging technological advances in medical equipment will probably be even more accurate and less invasive in the future.
