Anterolateral Tigh (ALT) Flaps Oxygenation Monitoring by NIRS
Tissue Oxygenation Monitoring of Anterolateral Thigh (ALT) Flaps, Using FORE-SIGHT ELITE Near InfraRed Spectroscopy (NIRS) - A Pilot Study
University Hospital, Antwerp
20 participants
Mar 3, 2025
OBSERVATIONAL
Conditions
Summary
The goal of this observational study is to conduct postoperative monitoring in patients who have undergone upper or lower limb reconstructive surgery with an anterolateral thigh flap, by employing the gold standard approach: intermittent assessment of clinical parameters (flap's color, temperature, skin turgor and capillary refill time) combined with Doppler techniques, alongside continuous tissue oxygenation measurements obtained using the CASMED FORE-SIGHT ELITE monitor.The main objective of the study is to provide preliminary data on potential cut-off values indicative of flap failure.
Eligibility
Inclusion Criteria1
- scheduled for reconstructive flap surgery on either upper or lower limb using a fasciocutaneous anterolateral thigh flap
Exclusion Criteria1
- refusal to provide written informed consent.

Interventions
Flap failure will be identified, based upon gold standard monitoring (flaps skin color, temperature, tissue turgor and capillary refill time) along with Doppler technique during a postoperative period of five days. In all patients Near Infrared Spectroscopy (NIRS) by FORE-SIGHT ELITE will be applied to obtain continuous tissue oxygenation measurements. NIRS values and trends from patients with flap failure (case group) will be compared to NIRS values and trends from patients with no flap failure(control group).
