1 Marsha M. Neumyer, BS, RVT, FSVU, FSDMS, FAIUM International Director Vascular Diagnostic Educational Services Vascular Resource Associates Harrisburg, PA Disclosure Statement: CME Calendar QR Code Marsha Neumyer, BS, RVT, FSVU, FSDMS, FAIUM has identified the following potential conflicts of interest: Speaker for Unetixs Vascular, Inc. and Gulfcoast Ultrasound, Inc. Independent Consultant for Pegasus Lectures All other persons involved in this CME Activity do not have any financial relationships with any commercial interest related to the content of this activity. This activity has not received any commercial support. Carotid Artery Duplex Scanning Recognized as the most accurate, noninvasive, costeffective method for diagnosis of extracranial cerebrovascular disease It is also recognized that optimal technique and quality instrumentation are of paramount importance in performing high quality examinations 1
2 Carotid Artery Duplex Scanning The vessels are superficial Every conceivable flow pattern Common vascular disorders observed Carotid Artery Duplex Scanning Anterior and posterior cerebral hemispheres are connected side-toside via the circle of Willis Evaluate vertebral and carotid arteries Obtain brachial systolic blood pressures Carotid Artery Duplex Scanning Two important technical components: B-Mode imaging May be complemented with color flow imaging Doppler velocity spectral analysis 2
3 B-Mode Imaging Intimal thickening Presence of plaque Plaque morphology Surface characteristics Abnormal anatomy B-Mode Imaging Normal Intimal Thickening Plaque Characterization 3
4 Plaque Characterization Acoustic characteristics Surface properties Multiple planes of view Plaque Characterization Acoustic pattern Homogeneous Heterogeneous Complex calcified Surface Characteristics Smooth Irregular Ulcerated (if crater more than 2 x 2 mm) Plaque Characterization Plaque Mobility Acoustically Homogeneous Plaque Acoustically Heterogeneous Plaque 4
5 Plaque Characterization Common Carotid Artery Acute Thrombus Plaque Characterization Occlusion??? Intraplaque Hemorrhage??? Complicated Lesions Plaque Characterization Hemorrhage into the plaque Subintimal necrosis Loss of intimal continuity Ulcer formation Calcification 5
6 Planes of View Normal Blood Flow Patterns 6
7 Normal Blood Flow Patterns Normal Blood Flow Patterns ICA ECA Normal Blood Flow Patterns Vertebral Artery Resembles ICA Rapid systolic upstroke Forward diastolic flow 7
8 Blood Flow Patterns Laminar Flow Minimal Flow Disturbance Blood Flow Patterns > 60% Stenosis 8
9 Post-stenotic Turbulence Found immediately distal to flow-limiting stenosis (> 60%) Decrease in peak systolic velocity compared to stenotic segment Disturbed outer frequency envelope Blood Flow Patterns Blood Flow Patterns Occluded Internal Carotid Artery Associated Common Carotid Spectral Waveform 9
10 Blood Flow Patterns Occluded Common Carotid Blood Flow Patterns CCA-distal obstruction Normal ICA ICA distal obstruction Blood Flow Patterns Cardiac arrhythmia 10
11 Spectral Doppler Analysis The Basis For Diagnosis Peak systolic velocity (PSV) End diastolic velocity (EDV) ICA / CCA peak systolic velocity ratio Post-stenotic turbulence B-Mode Image Measure the highest velocity where the intensity of the signal is maximal Measure EDV just before the next systolic upstroke PSV and EDV 11
12 ICA / CCA Velocity Ratio Measure the CCA velocity in the distal segment, 2-4 cm before the bulb Measure the highest PSV in the stenotic segment of the ICA Ratio is invalid if the CCA is abnormal Watch the Angle!!!!! The angle of insonation must be 60 degrees or less Doppler cursor parallel to the vessel wall Velocity estimation is inaccurate when angle of insonation is greater than 60 degrees 12

Presented at ACC Q9: In your opinion, if IAC Vascular Testing (ICAVL) developed one set of standardized diagnostic criteria that were researched and validated should laboratories be required to incorporate their use for accreditation? 31.6% No N=722 Responses for one set and required use of criteria highly correlated R=0.756, P<0.001 Yes 68.4% Gornik H, Needleman L, et al. Presented at ACC
18 How Do We Know What Criteria To Use?. The IAC Vascular Testing Board has recommended use of the SRU Criteria Laboratories may continue to use their own criteria as long as rigorous internal validation of those criteria can be confirmed. Future actions: The IAC plans to internally validate and make recommendations for specific ICA diagnostic criteria to be used by all facilities applying for accreditation. The future recommended diagnostic criteria may or not be identical to the SRU consensus criteria. A multi-disciplinary Carotid Diagnostic Criteria Committee has been formed by IAC Vascular Testing and will convene regularly to move this effort forward. Periodic status updates regarding the progress of this important initiative will be provided to IAC accredited vascular testing facilities. With this action, the IAC Vascular Testing BOD hopes that the documented variances in carotid stenosis interpretation can begin to be resolved 18
19 Although the technical protocols for carotid duplex evaluations have remained essentially unchanged for the past four decades, other factors influence current practice Addition of color and power Doppler imaging Refined definitions for plaque morphology and surface characteristics Changes in classifications of disease severity A call for standardization of ICA diagnostic criteria Recommendations from the ICAVL on adoption of new diagnostic criteria 19
