Application | Points of use for ICG intraoperative laser angiography |
---|---|
Free flaps | 1. Identify perforator perfusion zone in donor site prior to incision; select optimal perforator and design flap |
2. Confirm flap perfusion during dissection, testing and comparing different perforators | |
3. Confirm flap perfusion after transfer | |
4. Confirm patency of arterial and venous anastomoses | |
5. Detect areas of venous congestion by re-imaging 5–20 min after administration of ICG; can be performed following flap dissection, transfer, and/or inset | |
Pedicle flap | 1. Identify perforator perfusion zone in donor site prior to incision; design flap |
2. Evaluate arterial and venous perfusion after elevation of flap and prior to transfer | |
3. After transfer and after inset, confirm arterial inflow and venous return | |
Skin flap | 1. Evaluate perfusion prior to incision; design flap |
2. After dissection, confirm flap perfusion | |
3. After transfer and inset, confirm perfusion of flap | |
Mastectomy flap | 1. Following mastectomy, confirm integrity of vascular perfusion in mastectomy flaps; select delayed vs. immediate reconstruction; select implant vs. expander reconstruction |
 | 2. Confirm perfusion after insertion of reconstructive modality; determine expander volume or implant size; determine skin paddle size |
 | 3. If revisions made, confirm perfusion in flaps |
