As the occurrence of thrombosis in post surgery is rare, it seemed difficult to study only this one. This is why we decided to test the bioimpedance, temperature and green, red and infrared light absorption measurements of the prototype during the weaning of the flap during surgery. Indeed, during weaning the investigators voluntarily interrupt the arterial and venous flow to transfer the flap to the breast. This weaning corresponds to a thrombosis model.
The patients will benefit from an "improved" postoperative monitoring. Indeed, in addition to the classical clinical monitoring, they will benefit from an additional monitoring during 5 days thanks to the realization of an ultrasound of the flap which will be carried out every 6 hours the first 24 hours then every 12 hours.
This protocol is therefore a feasibility study for the collection of data of interest.
