Renal artery duplex ultrasound has been very successful in assessing renovascular hypertension. When renal artery velocities are within normal limits, but the Doppler spectral waveform is of small amplitude with a prolonged systolic rise, a more proximal arterial stenosis is suspected. We describe 2 cases of coarctation of the aorta in adults that were diagnosed with the assistance of aortic and renal artery duplex ultrasound.

Introduction: The aim of this study is to determine the degree of aging-related decrease in endothelial capacity for endothelium-dependent vasodilatation and its mutual inter-relation with increase in the stiffness of peripheral arteries. Methods: The reactive hyperemia test is useful for noninvasively evaluating the degree of endothelium-dependent vasodilatation. Stiffness index is a parameter used to evaluate vascular tonus and structural changes in the peripheral vasculature. The examination was done on 30 healthy respondents of both sexes and different ages, with no manifested risk factors and/or symptoms of cardiovascular diseases, to evaluate the influence of endothelium-dependent vasodilatation on the brachial artery and the influence of stiffness index on the common carotid artery. Results: With aging, the functional capacity of the endothelium for endothelium-dependent vasodilatation declines, in men as early as in their 20s, and in women more considerably after the age of 50 years. Over the course of aging, a significant stiffness increase was recorded in respondents of both sexes, the correlations being summarized in the following formulas: stiffness index = 0.028 × years of age + 5.0992 in male respondents, and stiffness index = 0.028 × years of age + 5.1991 in female respondents. Conclusion: Decrease in the capacity of peripheral arteries for endothelium-dependent vasodilatation correlates with increase in the stiffness of peripheral arteries.

The most common malposition seen during subclavian vein cannulation is to the ipsilateral internal jugular vein. We report a case of unusual malposition of a subclavian central venous catheter, where it was found to be forming a “figure of U” in the ipsilateral subclavian vein. Although the catheterization was done under ultrasound guidance, we could not visualize the course of the guidewire due to a poor ultrasound window. This report highlights the fact that although ultrasound can facilitate identification of the vessels and prevent inadvertent arterial puncture, it seldom helps in the positioning of the guidewire tip and prevention of catheter malposition.

Background: A Doppler peak systolic velocity (PSV) of 125 cm/s has been used to indicate an internal carotid artery 50% stenosis, a marker of large artery atherosclerosis (LAA) when classifying ischemic stroke according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST). Shifting this cut point to 180 cm/s might affect the classification of ischemic stroke. Methods: Color Doppler–assisted measurements of PSV were performed at the baseline visit of a large longitudinal cohort study in the United States: the Cardiovascular Health Study (CHS). Incident ischemic stroke within the following 6 years was ascertained by adjudicated review of medical records. The side of ischemic stroke was recorded. Incidence rates and odds ratios (logistic regression models) were estimated at the respective 125 cm/s and 180 cm/s cut points. Results: Mean age was 72.8 years with 57.6% women. A total of 11 425 bifurcations had PSV measurements. Of the 514 carotid bifurcations with PSV above 125 cm/s, 20 ipsilateral incident strokes were seen, whereas 6 strokes occurred among the 126 bifurcations with PSV above 180 cm/s. Shifting the cut point decreased categorizing ischemic stroke as due to LAA by 70% (14/20). The odds ratio (1.75; 95% confidence interval, 1.01-3.02) of incident stroke for a PSV between 125 cm/s and 180 cm/s was significant (P < .05) when compared with a PSV <125 cm/s. Conclusion: Shifting the PSV cut point for a 50% carotid stenosis from 125 cm/s to 180 cm/s would have significant implications when categorizing ischemic stroke as being associated with LAA.

Seattle University’s Bachelor of Science in Diagnostic Ultrasound Program was founded in 1978 and is accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) upon the recommendation of the Joint Review Committee on Education in Diagnostic Medical Sonography (JRC-DMS). The program has since evolved to offer post-baccalaureate degree and post-baccalaureate certificate pathways to students who already hold an undergraduate degree. The program now offers 3 distinctive specialty ultrasound tracks: cardiac, general, and vascular. While learning to perform quality ultrasound examinations at their assigned clinical site under the supervision of a clinical instructor, our students embark on an enriching journey toward their Senior Capstone project, where they delve into the realm of ultrasound technology, exploring its diverse applications that offer patients the best in quality of care. They empower their professional practice by integrating components of research design and reflecting upon their practical ultrasound clinical experience. Through rigorous research and critical analysis, they contribute valuable insights and advancements to the field, consisting of a literature review or an original research paper, along with engaging formal case presentations or a proposal at a sonography conference within their designated clinical specialty. Join us as we delve into the impressive work of 2 of our vascular track senior students, examining their captivating literature reviews that exemplify their dedication to excellence in ultrasound diagnostics.
