Various Therapies for Lymphedema and Chronic Venous Insufficiency, Including a Multimodal At-Home Nonpneumatic Compression Treatment.

ABSTRACT: Lymphedema and chronic venous insufficiency (CVI) affect millions of people and require lifelong management. Many compression options exist for the long-term management of these conditions; however, limitations in patient mobility and adherence are common. Current options for care often present challenges with adherence because they are time-intensive and cumbersome. Innovation is needed to improve compression options for patients with chronic edematous conditions, particularly because lymphedema and CVI benefit from combination interventions. In this narrative review, the authors focus on long-term management strategies for lymphedema and CVI and highlight a nonpneumatic compression device designed for ease of use in the management of lymphedema and CVI. Using a nonpneumatic compression device that combines multiple treatment modalities demonstrates improved efficacy, quality of life, and patient adherence.

Using noninvasive imaging to assess manual lymphatic drainage on lymphatic/venous responses in a spaceflight analog.

This retrospective case series (clinicaltrials.gov NCT06405282) used noninvasive imaging devices (NIID) to assess the effect of manual lymphatic drainage (MLD) on dermal/venous fluid distribution, perfusion, and temperature alterations of the head, neck, upper torso, and legs while in the 6-degree head-down tilt validated spaceflight analog. A lymphatic fluid scanner measured tissue dielectric constant levels. Near-infrared spectroscopy assessed perfusion, by measuring tissue oxygenation saturation. Long-wave infrared thermography measured tissue temperature gradients. Fifteen healthy, university students participated. NIID assessments were taken 1 minute after assuming the HDT position and then every 30 minutes, with MLD administered from 180 to 195 minutes. Subjects returned to the sitting position and were assessed at post-225 min NIID demonstrated significant changes from baseline (p < 0.01), although these changes at areas of interest varied. MLD had a reverse effect on all variables. NIID assessment supported the potential use of MLD to mitigate fluid shifts during a spaceflight analog.
