Abstract
Doppler ultrasound scan is a non-invasive, cheap and convenient tool and it complements angiography, Computed tomography angiography (CTA), magnetic resonance angiography (MRA) and catheter digital subtraction angiography (DSA) in screening, diagnosis, treatment and follow-up of peripheral vascular diseases. Symptoms of peripheral vascular diseases are becoming more common due to rise in incidence of diseases and risk factors (diabetes mellitus, dyslipidemias, smoking, sedentary lifestyle). Due to limited availability of highly specific tools such as CT angiography, magnetic resonance angiography (MRA) and DSA (digital subtraction angiography) in many developing countries, doppler ultrasound is gaining more importance. Early determination of peripheral arterial diseases is beneficial in prevention of complications as severity increases may cause intermittent claudication, pain, tissue loss, including ulceration and gangrene (as the diseases progresses) and early management of arteriosclerosis will be beneficial to prevent these complications.
Highlights
Doppler ultrasound scan is a highly useful non-invasive and reasonable tool for determination of CIMT, peripheral arterial diseases, renal artery stenosis due to atherosclerosis caused by diabetes mellitus, hyperlipidemia and smoking [1] [2] [3] [4]
Color Doppler arterial mapping is sufficient for decision making in the treatment these patients and can reduce rate and risks involved in performing of diagnostic angiography, CT angiography, magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) in many developing countries
Our study has demonstrated that DUS is accurate in determining the degree of stenosis present in lower extremity (PVD) peripheral vascular diseases
Summary
Doppler ultrasound scan is a highly useful non-invasive and reasonable tool for determination of CIMT, peripheral arterial diseases, renal artery stenosis due to atherosclerosis caused by diabetes mellitus, hyperlipidemia and smoking [1] [2] [3] [4]. Intra-arterial digital subtraction angiography (DSA), contrast enhanced magnetic resonance angiography (MRA) and computerized tomographic angiography (CTA) have been as imaging modalities in lower extremity ischemia. DSA gives the highest degree of spatial resolution and image quality It is the only modality where diagnosis and treatment of arterial diseases can be performed together. CTA is the technique of choice when evaluating patients with suspected mesenteric ischemia; it permits to differentiate between occlusive and non-occlusive etiologies [5] [6] Advances in both CTA (computed tomography angiography) and MRA (magnetic resonance angiography) provide clinicians the high resolution, 3-dimensional (3-D) road map of the peripheral arterial tree in patients when planning revascularization strategies. Grade III, 50% to 99% stenosis: monophasic waveform with an increase in peak systolic velocity ≥ 100% and marked spectral broadening. The aim/Objective of this study was to find the accuracy and compatibility of ultrasonography in diagnosis of lower extremity arterial diseases
