Edema caused by concurrent venous and lymphatic circulation insufficiency. Many, especially secondary, lymphedemas are due to concurrent venous circulation dysfunctions, therefore they are divided into three groups, depending on their respective clinical manifestations and timeframe:

• venous disorder with lymphatic involvement (lymphophlebedema);
• lymphatic disorder with venous involvement (phlebolymphedema proper);
• phlebolymphedema ab initio.
