Pdf Summary
The first study titled "Brachiocephalic and Right Subclavian Artery Disease: Patterns of Flow Abnormalities" examines the patterns of flow abnormalities in patients with brachiocephalic artery (BCA) and right subclavian artery (SCA) disease. The study found that BCA and SCA involvement with abnormal flows were most common, and abnormalities in the vertebral artery and upper extremity arteries were also common. The study concluded that technologists should be familiar with the recognizable waveform patterns associated with BCA and right SCA disease.<br /><br />The second study titled "Impact of Use of IAC vs SRU Carotid Interpretation Criteria on Patient Management" investigates the impact of using modified velocity criteria for carotid duplex interpretation introduced by the Intersocietal Accreditation Commission (IAC). The study found that redefining the carotid stenosis ranges using the new IAC criteria resulted in patients being reassigned to lower stenosis categories. The study emphasized the need for careful consideration of the impact of these changes on patient care and facility logistics.<br /><br />The third study titled "Reclassification of Ankle-Brachial Indices of 'Calcified' Arteries Based on Plantar Thermometry" explores the use of plantar temperature as a complementary variable to recalculate ankle-brachial indices (ABI) for patients suspected of having falsely elevated ABIs due to arterial "calcification." The study found that recalculation using the equation ABI = 0.3034 × plantar temperature - 9.0261 allowed for the reclassification of ABIs and provided additional information about arterial occlusive diseases.<br /><br />The fourth study titled "A New Transcranial Doppler Outcome Measure for Transcarotid Artery Revascularization Success" investigates whether flow improvement in the middle cerebral artery (MCA) can be used as a new outcome measure for carotid interventions such as transcarotid artery revascularization (TCAR). The study found that after successful TCAR, there was a significant increase in peak systolic acceleration (PSA) in the MCA, indicating improved blood flow to the brain. The researchers suggest that PSA can be used to determine improved flow of blood to the brain after carotid revascularization.<br /><br />The fifth study titled "Predicting Transcatheter Aortic Valve Replacement Success With a New Outcome Measure" examines the use of peak systolic acceleration (PSA) in the middle cerebral artery (MCA) waveform as a new tanscranial Doppler (TCD) parameter for transcatheter aortic valve replacement (TAVR) interventions. The study found that after successful TAVR, there was a significant increase in PSA, indicating improved blood flow to the brain. The researchers suggest that PSA can be used as a measure of improvement of blood flow to the brain after TAVR.<br /><br />The sixth study titled "Jugular Venous Reflux - A Pitfall of TCD Bubble Study" identifies internal jugular venous reflux (JVR) as a potential pitfall in transcranial Doppler bubble tests (TCD-BT) used to diagnose patent foramen ovale (PFO). The study found that internal JVR can cause misleading interpretations of TCD-BT, leading to false-positive results for PFO. The researchers emphasize the need for careful evaluation and interpretation of TCD-BT results.<br /><br />The seventh study titled "Transverse Visualization of the Vertebral Artery Can Significantly Improve Detection of Lesions In the Vertebral Artery (VA)" explores the use of transverse visualization of the vertebral artery (VA) in ultrasound examinations. The study found that transverse visualization allowed for more precise measurements of VA lesions, particularly in cases of VA dissection.<br /><br />The last study titled "Critical Limb Ischemia: The Impact of Frailty and Post-Intervention Perfusion on Outcomes" evaluates the impact of frailty and postprocedural success on outcomes in patients undergoing interventions for limb ischemia. The study found that post-procedure perfusion, as measured by pedal acceleration time (PAT), and severity of wound at presentation had an impact on 1-year amputation-free survival (AFS-1). Frailty, as measured by the modified Frailty Index (mFI), was found to be associated with a higher incidence of complications.<br /><br />Overall, these studies provide important insights into various aspects of vascular ultrasound and their implications for patient care and outcomes.
