2 Learning objectives To review the morphologic and hemodynamical changes in Chronic Venous Insufficiency in the lower limbs. To review the clinical manifestations and the most common patterns of Chronic Venous Insufficiency seen on Doppler Ultrasound and their therapeutic impact. To present a systematized Doppler Ultrasound protocol for thorough evaluation of the venous system in the lower limbs. Page 2 of 47

3 Background Chronic venous insufficiency is a major world-wide health problem. Doppler Ultrasound is an available, cheap, innocuous examination, which is nowadays widely implemented as the method of choice for assessment of the morphologic and hemodynamic changes of the venous system in the lower limbs.

4 Imaging findings OR Procedure details Chronic venous disorders depend on multifactorial risk factors and have a signifficant repercussion on the patient's lives and their families and represent ultimately a major economic impact in the community.

7 Fig.: Objectives of the Doppler-US examination. Awareness of the therapeutical impact of different clinical pictures is fundamental for enhanced diagnostic performance and management of chronic venous disorders. In our Department we perform Doppler-US in a methodic way, always bearing in mind the objectives of the examination and the available therapeutic options. Page 7 of 47

11 Fig.: Doppler-US examination. Consensual nomenclature is fundamental for proper multidisciplinary communication. The radiologist and the surgeon must have a clear mutual understanding of the venous disorders lexicon. A consensus meeting has recently published the most important physiologic terms on chronic venous disorders, which are presented below (in Updated terminology of chronic venous disorders, Journal of vascular Surgery, 2009).

15 Fig.: Physiological Venous Terms There are different methods for elliciting venous reflux; in our institution we use mostly distal manual compression and discompression. Page 15 of 47

16 Fig.: Assessment of venous reflux. One should be aware of the most common causes of false positives and false negatives, which preclude proper management of venous disease. Page 16 of 47

17 Fig.: Diagnostic Pitfalls The examination should be methodic and patient-tailored, always bearing in mind the specific information the surgeon needs in order to offer the patient the best therapeutics.

32 Fig.: The saphenopopliteal junction In the presence of saphenous vein reflux, it is important to provide detailed anatomical information on the location of the SPJ, since it will only be accessible through a popliteal crease incision if it is in the range of 5 cm. Otherwise, an incision in a different topography will be required. Page 32 of 47
