However, this can be cured quickly say within a couple of weeks but the stiffness in the vein will be felt over a period of time and takes more time to normal. Superficial thrombophlebitis: It is highly likely that you have superficial thrombophlebitis if the vein bulges along with the skin or if the skin over the vein darkens.Generally, the blood clot formed in the vein due to Deep Vein Thrombosis makes the surgery procedure riskier as it is located deep inside the body. DVT is common in people above the age of 50. Deep vein thrombosis (DVT): If you are a smoker or obese you are most likely to have DVT.Your medical physician may request you to take a Doppler Test when he/she suspects the following: Colour Doppler: With the help of the regular ultrasound procedures the images of the blood vessels are framed and the sound waves produce colors on the image to show the flowing bloodstreams’ direction and speed.Apart from this, the sound waves are used to create a graph showing the direction and the speed of blood flow. Duplex Doppler: General ultrasound techniques are used to generate images of the bloodstream vessels and the organs around them.The region of blood clot/narrow bloodstream is determined by the doctor by keenly observing the change in the pitch of the sound waves. Continuous-wave Doppler: The flow of blood in the vessels is analyzed by the pitch change in the sound wave.Once the test is done the gel is cleaned from the area. This is a minor test, takes 30 minutes and you will be asked to stay still throughout the process. Before the process, a medical gel is greased gently over the region of the projected blood clot/narrow blood flow, and a transducer is pressed and rolled over the applied gel to get the vision of the blood vessels. One big advantage of the Doppler test is that it doesn’t use any radiation, it is completely risk-free. This painless and risk-free test takes only thirty minutes to one hour and the results are also available to the patient as soon as the test is completed. The monitored sound waves are then permutated into graphs/images depending on the type of Doppler test.
