Addition of Intermittent Pneumatic Compression to Conventional Treatment Improves Volume Reduction Before Lymphatic Surgery for Lower Limb Lymphedema: A Pilot Study.

This study assesses the impact of an advanced intermittent pneumatic compression device (IPC - Lympha Press® Optimal Plus) when added to Complete Decongestive Therapy (CDT) compared to CDT alone on volume reduction of limbs with lymphedema. The goal is to maximally reduce edema in preparation for microsurgery. Fifty subjects scheduled for Multiple Lymphatic-Venous Anastomosis (MLVA) were randomly (sequentially) assigned to experimental or control group: 25 (21 females and 4 males) in the experimental IPC group and 25 (20 females and 5 males) in the control group. The two groups were similar in age, sex distribution, and type of lymphedema. Results indicate the IPC group reported greater volume loss than the control group (p= 0.00137) comparing final vs. initial limb volume. The average percentage edema volume loss achieved with added IPC was two times greater (11.7%) than in the control group (5.0%). When differences in treatment duration were accounted for, the IPC group achieved consistently greater proportional volume loss (12.83% vs 6.30%) than conservative therapy alone. In our pilot study, IPC added to CDT resulted in greater proportional volume loss and provides better preparation for MLVA surgery.
