The Intermittent Pneumatic Compression Influences Edema Fluid Movement and Promotes the Compensatory Drainage...

Introduction: Upper limb lymphedema is the most common complication after breast cancer therapy. Suddenly disturbed lymphatic transport in the affected arm causes tissue fluid accumulation in tissue spaces, limb enlargement, and secondary changes in tissue. Early compression therapy is necessary. We aim to evaluate the effectiveness of intermittent pneumatic compression (IPC) in fluid movement along the limb and the possibility of creating compensatory drainage pathways. Methods and Results: We investigated 25 patients with Breast Cancer Related Lymphedema (BCRL) stages II and III. Indocyanine green observation and measurement of skin water concentration and skin and subcutaneous tissue stiffness were done before and after a single 45-minute session of IPC. After IPC, we observed the movement of edema fluid upper in the arm (92%) and in three main directions not seen before IPC: to the ipsilateral supraclavicular lymph node (30%), to the ipsilateral axilla (22%), and to the axilla, chest, and scapula (26%). We noticed two changes in fluorescent intensity along the entire limb: a decrease in the hand and forearm, an increase in the arm (64%), and a decrease along some parts or the entire limb (36%). Skin and subcutaneous tissue stiffness decreased at all limb levels. The highest, statistically significant reduction of subcutaneous tissue stiffness was noticed in the middle forearm and elbow (36.4% and 33.4%, respectively). Conclusions: IPC can effectively move edema fluid from the distal to the proximal part of the limb, promote compensatory drainage pathways, and decrease tissue stiffness. This compression type should be applied even in the early stages to prevent limb enlargement and secondary tissue changes.
