Abstract

Background: Peripheral Arterial Disease Is a Major Problem Among the Population of Those 55 Years and Older. MDCT is a Non-Invasive Method of Visualization of Vascular System. It Affords More Widespread Vascular Screening, Allowing Diagnosis to be Made at an Early Stage. The objective is to Assess the Role of Multidetector Computed Tomography Angiography in Peripheral Arterial Disease of Lower Extremities. Subjects & Methods: A Prospective Study of 35 Patients with Signs and Symptoms of PVD, Were Subjected to Colour Doppler Ultrasonography and MDCT Examination Between a Period of 1st August 2018 to 31st May 2019. Results: Our Study Shows a Very Good Sensitivity, Specificity, PPV, NPV and Accuracy of Doppler in Assessing the Soft Plaque (82%, 100%, 100%, 97%, 97% Respectively) & in Evaluation of Stenosis Like <50% Stenosis (100%, 99%, 85%, 100% & 99% Respectively), 50-99% Stenosis (100%, 99%, 96%. 100% & 99.8% Respectively), & Occlusion (84%, 100%. 100%, 98% & 98% Respectively). The Only Parameter Which Showed Poor Result Was in Evaluation of Calcified Plaque. Conclusion: Our Study Shows that Both Colour Doppler & MDCT Can Be Complimentary in Lower Limb Arterial Disease Evaluation.

Highlights

Peripheral arterial disease (PAD) refers to atherosclerotic disease leads to development of plaques in the distal arteries, causing stenosis with compromised blood flow
The aim of our study is to evaluate lower limb arterial disease with new imaging modality such as multi-detector computed tomography (MDCT) and correlating the findings with that of colour doppler
MDCT has shown that it is accurate in identifying the degree, severity and level of peripheral vascular disease

Summary

Introduction

Peripheral arterial disease (PAD) refers to atherosclerotic disease leads to development of plaques in the distal arteries, causing stenosis with compromised blood flow It is more common in lower limbs than upper limbs.[1] Atherosclerosis of arteries distal to the aortic bifurcation called lowerextremity PAD. Recent advances in color Doppler, multi-detector computed tomography (MDCT) and contrast-enhanced magnetic resonance angiography (MRA) challenges the role of DSA.[4] Colour Doppler ultrasonography is a non-invasive method with good specificity and sensitivity. Doppler provides both anatomical and functional information, but it is not ideal for planning treatment. Conclusion: Our Study Shows that Both Colour Doppler & MDCT Can Be Complimentary in Lower Limb Arterial Disease Evaluation
