![]() ![]() Separate protocols for routine “limited” examinations may also be written. The documentation should match the written protocols in the laboratory. ![]() These represent the suggested minimum documentation requirements proper documentation often requires images in addition to those listed for completeness. Table 1 and Table 2 summarize the venous standards document of the IAC. The diagnostic techniques that identify venous obstruction are different from those required to identify valvular incompetence. Valvular reflux and obstruction (usually secondary to thrombosis) are the two key elements of examination during the lower extremity venous duplex ultrasound. Additionally, the technical aspects of the exam, anatomic variations, and hemodynamics are discussed with disease state considerations, all of which can have a profound effect on outcomes. This article presents the proper documentation requirements and a practical protocol for venous duplex ultrasound testing for vascular technologists and interpreting physicians. The Intersocietal Accreditation Commission (IAC) has revised reflux study recommendations, most recently in 2019, 1 and these are enforced in the accreditation process for vein centers. However, there is an educational gap to properly performing reflux studies. With the growth of interventional procedures for venous disease, duplex ultrasound has become the cornerstone for diagnosis and treatment. Over the past 2 decades, duplex ultrasound has impacted venous anatomic nomenclature, diagnosis, and treatment. ![]()
