Duplex ultrasound as a reliable alternative to CT angiography for treatment planning of peripheral artery disease

An ultrasound-based femoral artery calcification score

“…One imaging method commonly used to assess the extent of occlusive disease in patients with peripheral arterial disease (PAD) is arterial duplex ultrasound (US). 8 The findings from the assessment of arteries using duplex US correlate highly with those from other imaging methods, including CT and digital subtraction angiography. 8 , 9 Duplex US provides both anatomic detail and hemodynamic information that can guide procedures without the use of radiation or iodinated contrast agents.…”

“… 8 The findings from the assessment of arteries using duplex US correlate highly with those from other imaging methods, including CT and digital subtraction angiography. 8 , 9 Duplex US provides both anatomic detail and hemodynamic information that can guide procedures without the use of radiation or iodinated contrast agents. Although evidence of calcification is commonly noted on routine US evaluations of lower extremity arteries, the development of robust methods for assessing its extent has been limited, and efforts to link US-based calcification scores with outcomes have not been undertaken.…”

“…Although evidence of calcification is commonly noted on routine US evaluations of lower extremity arteries, the development of robust methods for assessing its extent has been limited, and efforts to link US-based calcification scores with outcomes have not been undertaken. 8 , 10 , 11 We, thus, sought to develop a standardized method of quantifying calcification on routine US images of the femoropopliteal artery, assess its correlation with CT-based methods, and determine whether elevated US-based calcium scores correlate with poor limb outcomes similar to the correlation with CT-based calcium scoring methods.…”

Early identification and treatment for peripheral arterial disease in patients with ischemic cerebrovascular disease

“…DUS has been increasingly used in the diagnosis of PAD recently because of its noninvasive, high detection rate, and repeatability. When compared with ABI, DUS can further determine vascular anatomy, hemodynamics, lesion morphology, and the severity of stenosis [ 31 ], and the results in diagnosing PAD are not easily affected by blood pressure (BP) fluctuation, body position, or latent small vessel disease [ 26 ]. Retrospective studies compared the efficacy of ABI and DUS in the diagnosis of PAD and found that in patients with lower-extremity artery stenosis > 50% on DUS examination, about 40% had normal/inconclusive resting ABI [ 32 , 33 ], which means that ABI has limited sensitivity for the detection of PAD compared with DUS.…”

“…Tương tự với nghiên cứu của Trương Quốc Vũ với tỷ lệ hẹp ≥ 50% là 51,2%, hẹp độ II chiếm nhiều hơn đáng kể so với độ III và độ IV [8]. Khác biệt với một số nghiên cứu như của Nông Thùy Linh (hẹp vừa là 15,9%, hẹp nặng là 43,9% và tắc là 40,9%) và Ombretta Martinelli trong 42/94 bệnh nhân hẹp có 7 bệnh nhân tắt động mạch [9,11]. Trong 13 bệnh nhân hẹp từ mức độ II, có 11 bệnh nhân hẹp từ 2 động mạch hẹp trở lên, vị trí hẹp nhiều nhất là ở vùng cẳng chân (63,16%), kế đến là đùi (15,78%) (Biểu đồ 3).…”
