what the risks are doppler ultrasonography of an extremity, this test uses ultrasound to examine the blood flow, in the major arteries, veins, in the arms, legs, test, in the ultrasound, radiology department, peripheral vascular lab, to examine the veins, a water-soluble gel, on the transducer, a handheld device that directs the high-frequency sound waves, artery, vein tested, skin over the veins, the extremity tested, "swishing" sound on the doppler venous, vein, system is normal, the superficial, deep venous systems, evaluated, to examine the arteries, blood pressure cuffs, put around the thigh, calf, ankle to examine the legs, arms, blood pressure cuffs, placed at different points, along the arm, a conductive paste is applied, skin over the arteries examined, cuff, inflated, above the normal systolic blood pressure, the extremity, transducer, near the cuff, pressure, in the cuff is released slowly, "swishing" is detected, recorded, the blood pressure, repeated, each cuff, , remove clothing, extremity examined, infants, children, test depends on child's age, prepare child, infant test/procedure preparation, birth to 1 year, toddler test/procedure preparation, 1 to 3 years, preschooler test/procedure preparation, 3 to 6 years, schoolage test/procedure preparation, 6 to 12 years, adolescent test/procedure preparation, 12 to 18 years, there is little, no discomfort associated, this test, an alternative to arteriography, venography, help diagnose a blood clot, venous insufficiency, arterial occlusion, closing, abnormalities, in the carotid artery blood flow, a narrowing, to evaluate trauma, arteries, monitor arterial reconstruction, bypass grafts, vessels show no evidence of narrowing, closure, arteries have normal systolic, diastolic components, blood pressure is normal, ankle-to-brachial arterial blood pressure index, comparison, the pressure, ankle to, the brachial artery, in the arm, 0.85, greater, veins, venous occlusion, closing of vein, blood clots, arteries, arterial occlusive disease, spastic arterial disease, arterial contractions brought on by cold, emotion, embolic arterial occlusion, obstruction, in the artery by a blood clot, a fat globule, an air bubble, additional conditions under which doppler ultrasound performed, aortic dissection, arteriosclerosis, the extremities, coarctation, the aorta, deep venous thrombosis, stroke secondary to carotid stenosis, superficial thrombophlebitis, svc obstruction, thromboangiitis obliterans, vascular tumors, the extremities, no risks specifically associated, cigarette smoking, the results of this test, nicotine, cause the arteries, in the extremities to constrict, quitting smoking significantly lowers the risk of problems, the heart, circulatory system, most smoking-related deaths, cardiovascular problems, not lung cancer.
