The Role of Duplex Scanning in the Selection of Patients with Critical Lower-Limb Ischemia for Infrainguinal Percutaneous Transluminal Angioplasty

Abstract

Duplex scanning can safely be used for the selection of patients for infrainguinal PTA. The sensitivity of duplex scanning in the selection of lesions for PTA was less satisfactory in the popliteal and crural arteries compared with the femoropopliteal arteries.

The Role of Color Doppler Ultrasound Arterial Mapping for Decision Making in the Treatment of Patients with Lower Extremity Peripheral Arterial Disease

“…In recent years, the role of duplex scanning as a prepro- cedural diagnostic imaging for detecting and grading occlusive disease of the lower limbs has been under dis-cussion comparing with angiography as a "gold standard" [13,14,16,17]. The ultimate purpose of the diagnostic tools is not only limited to draw an accurate anatomic arterial mapping but also to establish an appropriate therapeutic strategy, either surgical or endovascular [16].…”

In these literatures, there is increasing evidence to indicate the possibility that Duplex scanning should replace angiography in many patients for the therapeutic planning [13,14,16,17] especially in high risk patients with diabetes, renal failure or contrast agent allergy [18,19].…”

“…Las secuencias dinámicas en tiempos T1 3D con contraste, en conjunto con el movimiento rápido de la camilla en el momento de la adquisición de las imágenes, permiten obtener imágenes de todo el árbol arterial. La evaluación de la enfermedad arterial periférica con Angio-RNM permite realizar imágenes de las tres regiones de ambos MMII: aorto-ilíaca, femoropoplítea e infrapatelar 26 . La Angio-RNM identifi ca correctamente la enfermedad signifi cativa de la arteria poplítea con sensibilidad del 94% y especifi cidad del 92% y de las arterias tibiales con sensibilidad del 100% y especifi cidad de 84%, demostran-do mejor certeza diagnóstica en los segmentos infrapatelares en relación con la Angio-TC 27 .…”

“…18-7). [34][35][36][37] Duplex ultrasonography is also used in the postoperative surveillance of arterial bypass grafts. 32 In another meta-analysis of 14 studies, the sensitivity and specificity of duplex ultrasound with and without color-guided Doppler analysis to detect 50% or greater stenosis or occlusion was 93% and 95%, respectively.…”
