Aims and objectives: Background Lymphedema is a progressive pathologic condition in which protein-rich fluid accumulates in cutaneous and subcutaneous tissue due to disruption of lymphatic drainage function [1]. Over time, chronic lymphedema leads to inflammation, hypertrophy of adipose tissue and eventually tissue fibr[...]

Methods and materials: Patients Between July 2015 and November 2016, 58 consecutive patients with clinically proved limb lymphedema referred from the Department of Plastic and Reconstructive Surgery, Chang Gung Memorial Hospital, Linkou, Taiwan, were recruited for clinical evaluation, ARFI ultrasound elastography and lymp[...]

Results: One hundred and six limbs in 53 patients with lymphedema were evaluated with conventional B-mode ultrasounography and ARFI elastography. The characteristics of the patients were shown in table 1. Mean BMI of the patients was 25.1 (range, 18 – 34). Eighteen patients were in grade I lymphedema, 19 pat[...]

Conclusion: Using ARFI, we found that skin and subcutaneous tissue are stiffer in symptomatic limbs than in unaffected limbs in patients with limb lymphedema. Higher tissue stiffness was found in limbs with lymphatic drainage obstruction shown on lymphoscintigraphy. Skin and subcutaneous tissue shear wave veloc[...]
