Arterial Inflow and Muscle Ischemia During Calf Stimulation With the Veinoplus Device

Summary

Stimulation of arterial inflow to the lower limb is important to obtain functional improvement in peripheral artery diseased (PAD) patients with claudication. The clinical effect of muscle stimulation to increase arterial inflow and the direct evaluation of the regional blood flow impairment (RBFI) in the area of stimulation, have not been evaluated in PAD patients.

Fifteen adult patients with stable arterial claudication will participate. Recruitment will be performed among patients referred for exercise oxymetry (treadmill: 3.2km.h-1, 10% slope) After two minutes of rest, the gastrocnemius will be stimulated for 20 minutes at an increasing frequency rate with 5 min steps (1 Hz, 1.25 Hz, 1.5 Hz and 1.75 Hz) on the most symptomatic side.

The investigators record the tcpo2 value, arterial blood inflow with ultrasound of the femoral artery, and near infra-red spectrometry (NIRS) on both sides.

Patients will be instructed to report eventual contraction-induced pain in the stimulated calf.
