12/11/2023 0 Comments Lower extremity doppler![]() ![]() Upper extremity PVD most often affects patients with previous upper extremity vein thrombosis or trauma, recent or past surgery on the affected extremity (recent or prior dialysis access graft surgery, dialysis catheter, central venous line or chemotherapy access port insertions), and history of cancer. ![]() An arterial duplex ultrasound uses sound waves to create a color map of the arteries in your legs to identify: Narrowing of your vessels that may be causing leg pain when walking. Patients at an increased risk for lower extremity peripheral venous disease may include those with previous deep vein and/or superficial vein thrombosis (DVT/SVT), lower extremity trauma, immobilization of extremity, recent major surgery, prolonged bed rest, history of cancer, family history of DVT, pregnancy, congestive heart failure (CHF) or other similar cardiac problems. Ultrasound is a procedure that uses sound waves to 'see' inside your body. Predisposing factors for venous thromboembolism include cancer, previous DVT, inherited hypercoagulable conditions, and inflammatory diseases 1,2,3. In addition, this procedure may be used to detect superficial phlebitis and obstruction. Acute pulmonary embolism (PE) is thought to originate from lower extremity deep venous thrombosis (DVT) in most cases. ![]() Acute and chronic thrombosis can be differentiated. Venous duplex imaging is used to evaluate blood clots, venous insufficiency, incompetence or tumor/masses obstructed veins. Venous Duplex – Upper and Lower Extremities lower extremities by means of Doppler technique to establish a quantitative relationship be - tween volume flow and pulsatility index (PI) in both healthy subjects and patients with pe-ripheral artery disease (PAD) and to derive arterial blood flow equations in the lower extrem-ities for more accurate volume flow estimations. ![]()
