Angiography - The Medical Photography

Angiography, when heard speak, recalls always the machine showing a graph with risky lines from top and bottom with the pulse of the heart... and the only thing we understand is the horizontal straight line!But, angiography is not. It is medical photography in simple terms. For medical reasons, is an imaging technique using x-ray of the blood vessels or heart cavity examination, including the veins and arteries.This word has Greek roots graphein meaning 'to write or record' and the angeion meaning "ship". The image is called angiograpgh or angiography and the process is called angiography or Arteriography. This technique has been developed by the Portuguese physician and neurologist Egas Moniz 1927.The process of coronary angiography, a wire/tube called catheter is inserted into the artery either the arm or the thigh and placed near the heart or the opening of the arteries supplying the heart. A special liquid called dye or contrast medium is injected and is visible by x-ray and images are called angiograms. Coronary tubes, if completely filled by injected dye, is interpreted as no blockage in the arteries, while if there is a failure to fill, there is a deadlock, which is a rough estimate.The end of the catheter reaches the coronary tube by the method of trials and errors. The tip is displayed on the x-ray monitor (which has strong radiation) and pushed against the arteries to reach a coronary artery. The danger of this test-error method is that it can scratch the arterial tube of body length and can punch any corner of the tubes. Also, there is always a risk of bleeding, and pain at the IV site and the formation of blood clots may be formed on catheters, blocking later some other blood vessels. Contrast material could also damage the kidneys, so it must be always careful.The percentage of complications in coronary angiography is as low as 1 in 1000. Death, myocardial infarction, ventricular arrhythmia severe stroke cerebral and major vascular complications of each occur in less than 1% of patients who undergo a catheterization. This is cardiac arrhythmias, kidney damage, blood clots (which can cause a heart attack or stroke), hypotension and pericardial effusion, and many others. Everything can be complications, the improvement of technology and expertise as doctors online, leaving a very trivial scope for it.True, it is that the technology that has reached our hearts today!
