Bioimpedance Variation of Free Flap for After Clamping

Not Applicable

Completed

• Conditions: Thrombosis

• Registration Number: NCT03118115
• Lead Sponsor: Centre Hospitalier Universitaire, Amiens

Brief Summary

MONITRANS project consist of developing a monitoring technology of post-operative breast reconstruction by detecting thrombosis. Its aim is to reducing time spent in hospital by monitoring patients at home.

Thrombosis following to abdominal free flap harvesting for breast reconstruction is a rare phenomenon (with a 2 until 15 % frequency). Moreover, it leads to ischemia by limiting water intake in the plasma compartments. The investigator would like to prove, by this research project, that they are able to detect ischemia via bioimpedance technology.

During abdominal free flap harvesting for breast reconstruction, there are few minutes where the flap is clamped because of anastomosis on the recipient vessels. The investigators would seize the opportunity of this step, which is similar to vascular thrombosis, to measure bioimpedance variations.

Therefore they would like to measure variations of the flap bioimpedance before and after vascular section. Another purpose consists of developing an algorithm which will detect postoperative thrombosis.
