Summary
High-frequency ultrasound (HFUS) improves perforator mapping for anterolateral thigh (ALT) and superficial circumflex iliac artery perforator (SCIP) flaps. This technique reduces flap elevation time and perfusion-related complications, especially for thin flaps.
Area of Science:
- Microsurgery and reconstructive surgery.
- Medical imaging and diagnostic techniques.
Background:
- Accurate perforator mapping is crucial for successful thin perforator flap elevation in reconstructive surgery.
- Conventional methods like handheld Doppler have limitations in visualizing superficial perforator anatomy.
- High-frequency ultrasound (HFUS) offers potential for detailed visualization of superficial structures.
Observation:
- A retrospective review compared handheld Doppler with HFUS for anterolateral thigh (ALT) and superficial circumflex iliac artery perforator (SCIP) flap reconstructions.
- Flap elevation time showed a trend toward reduction with HFUS, particularly for super-thin ALT and pure-skin-perforator SCIP flaps.
- Perfusion-related complication (PRC) rates, including partial flap necrosis, were significantly lower in the HFUS group.
Findings:
- HFUS mapping was associated with decreased flap harvesting time compared to handheld Doppler.
- The HFUS group demonstrated significantly lower rates of perfusion-related complications, notably partial flap necrosis.
- Multivariable analyses confirmed the significant benefit of HFUS in reducing complications.
Implications:
- HFUS is a promising tool for perforator mapping in reconstructive surgery, enhancing outcomes for thin ALT and SCIP flaps.
- Adoption of HFUS may lead to improved surgical efficiency and reduced complication rates in perforator flap procedures.
- This modality can potentially improve the reliability and safety of complex reconstructive surgeries utilizing perforator flaps.
