The anterolateral thigh flap is a versatile and dependable perforator flap and is a popular choice in the reconstruction of various body sites. The variable perforator anatomy suggests preoperative perforator imaging to improve safety and speed of dissection. An innovative perforator imaging technique is thermography, which lately gained attention in plastic surgery.
Thirty-two healthy participants were included in this randomized study. One thigh was examined with dynamic infrared thermography and consecutively with ultrasound, while the contralateral thigh was examined with ultrasound as standalone technology.
The application of dynamic infrared thermography prior to ultrasound perforator identification significantly accelerated the ultrasound examination duration by 90 to 130 seconds. The mean duplex ultrasound examination duration correlated positively with the hotspot and perforator quantity per thigh.
The addition of thermographic perforator mapping can accelerate color duplex ultrasound anterolateral thigh perforator imaging. Furthermore, thermography supplements color duplex ultrasound with crucial information on angiosome location.
股前外侧皮瓣是一种多功能且可靠的穿支皮瓣，是重建各种身体部位的常用选择。可变的穿支解剖结构表明术前穿支成像可以提高安全性和解剖速度。一种创新的穿支成像技术是热成像，它最近在整形外科学中受到关注。
本研究纳入 32 名健康参与者。一条大腿接受动态红外热成像检查，然后连续接受超声检查，而对侧大腿仅接受超声检查作为独立技术。
在超声穿支识别之前应用动态红外热成像可使超声检查时间平均缩短 90 至 130 秒。双功能超声检查的平均时间与热点和每条大腿的穿支数量呈正相关。
添加热成像穿支定位可以加速彩色双功能超声股前外侧穿支成像。此外，热成像用血管分布区的关键信息补充了彩色双功能超声。
