Summary
Transit time flow measurement (TTFM) is effective for assessing microvascular arterial anastomoses in radial forearm flaps, improving surgical outcomes. This method provides objective data and aids in optimizing flap vascularization.
Area of Science:
- Plastic Surgery
- Vascular Surgery
- Surgical Technology
Background:
- Coronary artery bypass graft outcomes have improved with transit time flow measurement (TTFM) in microvascular anastomoses.
- This study investigates TTFM's applicability for evaluating radial forearm flap arterial anastomoses.
Observation:
- A prospective study used ultrasound imaging and TTFM (VeriQ, MediStim) on 15 radial forearm flaps.
- Mean blood flow and pulsatility index (PI) were measured immediately and 15 minutes post-anastomosis.
- Device setup, probe placement, and measurements took approximately 20 minutes, with uncomplicated handling.
Findings:
- No statistically significant differences were observed in mean blood flow (p=0.96) or pulsatility index (p=0.09) between immediate and 15-minute post-anastomosis measurements.
- Atypical pulse curves led to surgical revision in 2 cases, with all flaps showing good vascularization post-operatively.
- TTFM provided objective results and aided in improving anastomotic quality.
Implications:
- Transit time flow measurement enhances the quality and outcomes of radial forearm flaps.
- The technique offers objective data for surgical assessment and documentation in microvascular reconstruction.
- TTFM is a valuable tool for optimizing microvascular arterial anastomoses in reconstructive surgery.
