In the past years the anterolateral thigh flap has become a workhorse flap in the reconstruction of the head and neck region and the extremities. Due to its variable vascular anatomy the preoperative assessment of perforators has been performed using several devices.
In our study we investigated the reliability of Doppler sonography and colour Doppler sonography for this purpose in 14 patients undergoing reconstruction with anterolateral thigh flaps. Colour Doppler sonography identified 31 perforators preoperatively, which were all identified during flap harvest. Doppler sonography found 25 true positive signals, 11 false positive signals and 6 false negative signals.
Both procedures provide a simple and rapid method for the localisation of ALT perforators. However, colour Doppler sonography showed a significantly higher reliability in identifying perforators of anterolateral thigh flaps, thus enabling flap design around preoperatively confirmed perforators.
在过去几年中,股前外侧皮瓣已成为头颈部和四肢重建中的常用皮瓣。由于其血管解剖结构多变,术前已使用多种设备对穿支进行评估。
在我们的研究中,我们对14例行股前外侧皮瓣重建术的患者,为此目的研究了多普勒超声和彩色多普勒超声的可靠性。彩色多普勒超声术前识别出31个穿支,在皮瓣切取时均得以确认。多普勒超声发现25个真阳性信号、11个假阳性信号和6个假阴性信号。
两种方法都为股前外侧皮瓣穿支的定位提供了一种简单快速的方法。然而,彩色多普勒超声在识别股前外侧皮瓣穿支方面显示出显著更高的可靠性,从而能够围绕术前确认的穿支进行皮瓣设计。
