Advancing Tissue Assessment

Plastic Surgery

Rapid identification of healthy and at risk tissue which aids and supports surgical decisions. Begin assessing immediately. No waiting for injected dyes, set-up, or additional personnel. Simply and quickly image patients and repeat as desired. Customize your surgical procedure to your patient and  assess tissue viability in all care settings.

SnapshotNIR, provides images of deoxygenated hemoglobin, oxygenated hemoglobin, and total hemoglobin in addition to the resultant StO2 images. These tools combined can help distinguish between arterial or venous insufficiency and guide the surgeon to corrective measures preoperativly, intraoperativly, postoperativy, and in the clinic. Ultimately, determining a skin flap has limited blood supply earlier may lead to less patient suffering and reduced healthcare costs.

Breast Reconstruction Case Reports

Case 1: Prepectoral Reconstruction -Precise visualization of tissue oxygenation compliments surgical judgement.

Patient presented positive for left sided breast cancer. Direct to implant prepectoral reconstruction was successfully completed. Surgeon was confident in reconstruction after observing well oxygenated flap with final implant in place.

Case 3: Lumpectomy with Breast Reduction -Mitigate risks early and identify healthy, damaged, and necrotic tissue.

Patient presented with breast cancer. Underwent tumor removal and breast reduction. Lower medial pole showed decreased oxygenation however went on to heal well. Surgeon was able to monitor in post operative oxygenation assessment and confirm confidence in flap viability.

Case 2: Tissue Expander Reconstruction - Assess appropriate expansion with unlimited and repeatable imaging

Patient presented positive for right sided breast cancer. Skin sparing mastectomy was performed and underwent expander based reconstruction. Flap oxygenation was excellent after expansion

Case 4: Tram Flap Reconstruction -Rapid identification of healthy and at risk tissue supports surgical decision making.

Patient presented positive for left sided breast cancer. Elected a Transverse Rectus Myocutaneous (TRAM) Flap reconstruction. Flap edges are observed to have decreased oxygenation providing the surgeon well demarcated edges selecting the best tissue for breast creation.

Portable For All Points of Care

Pre-operative Planning: Establish baseline oxygenation to help plan and identify at risk tissue before the procedure begins.
Intra-operative Flap Assessment: Assess surgically manipulated or altered tissue to determine flap viability.
Post-operative Surveillance: Continued surveillance in recovery ensures tissue survival and identification of congested flaps prior to discharge.
Follow-up Visit Tracking: Evaluate areas of concern to ensure continued positive flap health. The ability to optimize expansion  by maximally filling while ensuring tissue viability throughout each visit.
In Clinic Monitoring: Ability to assess dehisced or slow healing wounds without the need for injections or contrast.
