Doppler: How to conduct the investigation and analysis of the results
Dupler -ultras round, Dupplex with a sponsorship that used Doppler to assess the blood flow in the blood vessels, and this examination is conducted using a transducer transformer that is linked to the computer that sends waves in the ultrasound or characterized by ultrasound, which is not heard by man and then captures. Astage. If the red blood cells flow into the blood vessels, it reflects the sound waves other than what it does when they do not flow, and the computer connected to a computer translates the information received on the device and produces an image or sound that indicates the flow density and sometimes its direction. There are also small Doppler devices aimed at the blood flow examination, and the duplex term is used to describe the Doppler device that forms a two -dimensional image, as opposed to ordinary Doppler that provides information about one dimension. When is the test made? It can help to detect the following: thrombosis, narrowing or blockage of blood vessels (blockages) in different parts of the body, especially in the neck, arms and legs, so that the blood vessels narrow in the neck, it can cause faint, rotation and also soothing. It helps to detect a stroke in the deep bloods in the bone, and it is known as DVT thrombosis deep vein, which causes pain and poses a risk of developing pulmonary obsessively ( – pulmonary embolism), and also poses a great risk to the patient’s life, can cause the bones to be lost in the bones. In addition, the exposure to the narrowing of the blood vessels helps and the degree of risk of the doctor to make the decision on whether there is a need for treatment, as well as determining the type of treatment. Determine the abnormal veins, as in the case of varicose veins. Coronary bypass operations can be used to check the degree of blood flow in these blood vessels intended to convert their passage. This investigation may also help with the following: Evaluation of blood flow to the kidney transplant. To vascular surgery to determine the blood flow. Identifying uncertainty before the treatment aimed at eradicating it (Abrat). Evaluation of blood flow in the placenta, umbilical cord and the brain of the fetus in the investigation into ultrasound for pregnant women. Evaluation of blood flow in cancer crops. The risk category The Doppler test with an ultrasound is similar to an ordinary ultrasound test, it is not an introsive (invasive) and does not hold any risk, and as a regular ultrasound test it is difficult to perform a blood vessel examination if they are under the legs or under the legs. For example, if the patient cannot move like young children, the investigation cannot be performed without anesthesia or calm (irrgurular rit), the results of the Doppler test may be less credible; This is because blood flow can look abnormal, even if the blood vessels are intact. Related diseases include diseases with this investigation into the following: deep -depth thrombosis. Pulmonary embolism – PE. Crops. Isoimmunizanization rh. Preclampsia. Sickle cell anemia. The examination method is performed by a Doppler investigation in the same way as the usual ultrasound, as the transformer is placed in the area after the gel is applied to the examination area. Try and reduce the movement as much as possible, and you can hear sounds that represent blood flow in the blood vessels. A blood vessel examination of the limbs can be performed in the laying or sitting position, and sometimes made after a certain attempt if the patient’s health allows, and this investigation may also include the installation of the blood pressure system to measure the arms or legs to measure the pressure when the flow stops at different points. The converter is transferred to different parts of the limbs and can push certain areas to verify the presence of blood clots or to investigate the intravenous blood flow. Preparing for examination may be necessary not to use products that contain nicotine, such as cigarettes, for example, two hours before the Doppler examination, as nicotine can lead to the contraction of blood vessels and the credibility of the results can affect, it should be noted that there are no instructions for the investigation into investigation. Results -Analysis contains the possible results of this investigation on the following: 1. The results are healthy which includes the following: There are no disorders in the arterial blood flow. There are no disorders in venous blood flow and no blood clots have been seen. The blood flow in the blood vessels of the fetus is healthy. 2.. The improper results received by the veins when examining the arteries of the neck, called carotids, and it appears that there is a blockage of more than 80 % in the person without related complaints, or if there is a blockage of more than 50-60 % in a person with related complaints, it requires surgery to open the blocking. The investigation can reveal the expansion of the blood vessels in the areas where the arterial walls are weakened, and the growing balloon is created in the blood vessels. The veins reveal the expansion of the veins or the so -invented varicose veins. Blood clots if blood clots occur in deep veins, you may need an anticoagulant treatment to reduce the risk of pulmonary embolism (pulmonary embolism).
