In patients with critical limb ischemia (CLI) and foot ulcers wound healing is an important goal which can normally only be achieved after sufficient treatment of the underlying ischemia (revascularization either by an operation, e. g. bypass, or a catheter intervention). After successful revascularization everything should be done to improve wound healing because this regularly takes weeks up to several months. One possibility to speed up healing could be treatment with the VADOplex device which delivers an automatic intermittent painless compression of the sole of the foot thereby increasing perfusion of the leg. This system can be easily operated by patients themselves and at home.
Our goal is to prove that the VADOPlex system accelerates healing up and improves quality of life.

- wound healing [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]complete healing of the target lesion
- change of quality of life [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]change of quality of life compared to baseline. Quality of life measured with the EQ-5D tool (European quality of life in 5 dimensions)
- time to complete wound healing [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]time until complete wound healing of the target lesion is achieved
- Wound size [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]overall reduction of the size of the target lesion in patients with incomplete wound healing compared to baseline
- change of pain intensity [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]change of pain intensity compared to baseline. Pain intensity measured with a numeric rating scale (0 - 10) or if not applicable with a visual analogue scale
- change of ankle-brachial index [ Time Frame: at discharge, 2 weeks, 4 weeks, 8 weeks, 12 weeks and 24 weeks after discharge ]change of ankle-brachial index compared to basleline
- incidence of deep vein thrombosis [ Time Frame: 24 weeks after discharge or whenever a thrombosis is suspected ]
