A Prospective Feasibility Study of Duplex Ultrasound Arterial Mapping, Digital-Subtraction Angiography, and Magnetic Resonance Angiography in Management of Critical Lower Limb Ischemia by Endovascular Revascularization

Utility of duplex ultrasound in detecting and grading de novo femoropopliteal lesions

“…Replacing DSA with a noninvasive diagnostic technique will reduce contrast-related complications, patient discomfort, and may also save costs. [3][4][5] Duplex ultrasound (DUS) is a noninvasive technique for evaluation of peripheral vascular disease and previous studies have shown good agreement between DUS and DSA. [6][7][8][9][10][11][12][13] It is easy to perform, has no side effects, and is relatively inexpensive.…”

Sequential compression biomechanical device in patients with critical limb ischemia and nonreconstructible peripheral vascular disease

“…If DUAM failed to show any outflow vessels, yet the patient was deemed fit to withstand a revascularization procedure, then further imaging was done with computed tomographic angiography (CTA) or magnetic resonance angiography (MRA), or both. 18 If neither modalities showed any reconstructible outflow, and the patient had tissue loss and was fit for revascularization, then the presence or absence of any options for revascularization was confirmed with on-table digital subtraction angiography (DSA). 18 SCBD protocol.…”

“…18 If neither modalities showed any reconstructible outflow, and the patient had tissue loss and was fit for revascularization, then the presence or absence of any options for revascularization was confirmed with on-table digital subtraction angiography (DSA). 18 SCBD protocol. After obtaining informed consent, patients were commenced on a treatment protocol that lasted 12 weeks 5 or until they required amputation.…”

Characterization of tibial velocities by duplex ultrasound in severe peripheral arterial disease and controls

“…Following the procedure, ABI improvement and patency of reconstruction are similar when DUS or CA is used for preoperative planning. 2,3,[6][7][8][9] These studies have also shown that the accuracy and concordance of DUS with CA are not dependent on PAD severity (claudication vs CLI) or adjacent disease. 10,11 Concordance between DUS and CA is best in the suprageniculate arteries of the lower extremity.…”
