Wound Necrosis in Lower Extremity Surgery

Completed
Conditions
Extremity Lower Wounds
Interventions
Combination Product: SPY Intra-operative Angiography
Registration Number
NCT03351387
Lead Sponsor
Mayo Clinic
Brief Summary

Researchers are performing this study to evaluate if intraoperative angiography can be shown numerically to determine which wounds are at high risk of wound necrosis/breakdown.

Detailed Description

At the beginning of the Participants surgical procedure, a picture will be obtained using intraoperative angiography using ICG dye which the camera can detect. This dye will be provided through intravenous access. The picture will be taken of the wound to determine preoperative blood flow to the area where the incision is planned. After the wound has been closed postoperatively, a final picture, using the procedure described above, will be taken to determine blood flow after closure of the wound. These images will be obtained using intraoperative angiography. The Participant will be followed after the surgical procedure at standard intervals as determined by the surgeon until the wound heals or requires further intervention.
