Tissue Oxygenation Measurements With Modulated Light (S-FLARE)

Phase 1
Completed
Conditions
Breast Cancer
Interventions
Device: Imaging with S-FLARE imaging system
Registration Number
NCT01116297
Lead Sponsor
Beth Israel Deaconess Medical Center
Brief Summary

To perform a pilot study of the S-FLARE imaging system, which uses low levels of safe, invisible, near-infrared light to measure tissue oxygenation during breast reconstructive surgery and to compare S-FLARE measurements to the gold standard, FDA-approved, the ViOptix optical probe.

Detailed Description

This pilot study will enroll three patients who have chosen to proceed with deep inferior epigastric perforator (DIEP) flap breast reconstruction. This type of reconstruction uses skin and fat from the abdomen to reconstruct a new breast shape. The construct is vascularized through perforating arteries and veins that provide a blood supply to this tissue.

Current techniques to evaluate vessel selection rely on a handheld Doppler used for confirmation of blood flow and perfusion; however, this modality is limited as it only assesses a specific point within the flap.

The S-FLARE imaging system will be used to visualize vascularization in the DIEP flaps, and this study will compare measurements by the S-FLARE imaging system and the standard-of-care ViOptix point probe.

Due to patient-to-patient anatomic variation, the vascular perfusion to the skin in DIEP flaps is unpredictable and of great concern to the surgeon planning the flap design. We propose a method of imaging tissue oxygenation within a DIEP flap base on the use of invisible near-infrared light.

This pilot study is a comparison study of oxygenation measurements taken by the ViOptix optical probe as the standard of care and the S-FLARE imaging system, with the intention of optimizing the ergonomics and functionality of the S-FLARE imaging system for use during breast reconstructive surgery.
