The lower extremity venous system includes the superficial, deep, and perforating veins. The main pathologies that affect the venous system of the lower extremities can be due to the development of thrombosis within the veins or abnormalities in venous valve function.
Deep vein thrombosis (DVT) is a condition in which a blood clot (“thrombus”) forms most often in the deep veins of the legs, groin or arm thus causing partial or complete obstruction of the venous flow.
Although DVT is rarely life-threatening on its own, it has the potential to cause pulmonary embolism (PE), which can be fatal.
The diagnostic approach to suspected symptomatic deep vein thrombosis of the lower extremities is usually based on physical examination and non-invasive methods, including the pretest clinical probability (using the validated Wells score), the measurement of D-dimer levels, and ultrasonography. Venous Ultrasound of the lower limb veins is the first line imaging to detect the presence of a DVT as well as in describing which veins of the legs are involved.
When a thrombus is found within a superficial vein, thi is defined as superficial vein thrombosis (SVT). SVT is most often a complication of varicose veins and, although is not clinically dangerous, a duplex assessment is advised to exclude the presence of a concomitant DVT.
Chronic venous disease, defined as “(any) morphological and functional abnormalities of the venous system of long duration manifest either by symptoms and/or signs indicating the need for investigation and/or care” is a very common and often underdiagnosed disease of the lower limb veins that can impair quality of life.
It can present with different manifestations, ranging from telangiectasias, reticular veins, varicose veins, oedema to skin disorders and venous ulcers.
The exact pathophysiology is debated, but it involves a genetic predisposition, incompetent valves, weakened vascular walls, and increased intravenous pressure. Potential complications include infection, leg ulcers, stasis changes, and SVT.
Duplex ultrasound (DUS) is the first line diagnostic tool used to assess the anatomy and function of the vascular system. In patients with CVD, it allows to assess the venous system anatomy, evaluate patency and continence of the superficial and deep veins as well as to describe venous incompetence pattern. This information is of paramount importance to define the best treatment plan for individual patients.
This online accredited course is designed to provide ultrasound practitioners with the fundamentals to perform a lower limb venous assessment for deep vein thrombosis and venous insufficiency.
The course is made of e-booklets supported by hands-on commented video lectures and covers all the main topics of carotid and vertebral ultrasound imaging, such as:
Furthermore, the course illustrates the different ultrasound diagnostic criteria and scanning protocols used for:
The content of the course is continuously implemented and updated.
At the end of this course, the ultrasound practitioners will have acquired enough knowledge on how to detect a deep and superficial veins thrombosis of the lower limbs as well as how to assess lower limbs for the presence of superficial and deep venous incompetence/reflux.
Learn lower limb venous ultrasound with ABC online courses. At the end of the course an European certificate of accreditation and 12 CME AMA PRA credits will be released to the learner after successfully passing multiple choice quizzes.
