Many are the reasons for patients to be sent to daily practice for an ultrasonographic assessment, especially when signs and symptoms, whether single or concomitant, are expressed as peri-malleolar edema or whole limb edema. Our experience with patients who have venolymphatic insufficiency, neoplastic diseases, surgery (whether for trauma, abdominal, orthopedic or gynecological reasons), tropical strip parasitic diseases, radiotherapy and chemotherapy, has given ultrasound the opportunity to delve in diverse conceptions of the types and extension of edemas, thus providing us with a first-line clinical diagnostic method, together with ineffable clinical assessment, for the recognition and differential diagnosis of the variety of lymphostasis that may affect the lower extremities. One of the most important aspects is the differentiation of venous occlusive vascular involvement from other clinical conditions that may produce significant lymphatic sequestration due to an overload of venous return in the cases of venous occlusion or subocclusions in lower limb thromboembolism. With regards to this diagnostic aid, we have carried out a review and have briefly characterized the types of edema that we see, as well as the manner to recognize them in order to contribute with a major diagnostic and prognostic element for the assessment of patients’ clinical and therapeutic evolution. In fact, the first assessment of the lower extremity, which allows to integrally identify soft tissue lesions, any type of vascular involvement, the presence of foreign bodies, perfusion or obstruction levels and, thus, the presence, extension, level and general status of lymphostatic involvement, is currently one of the most frequent reasons for patients reference to diagnostic laboratories. This encourages us to always present better aspects of this method and of its capabilities.
